     1. Field 
     The disclosure relates to a battery and an electronic device including the same. 
     2. Description of Related Art 
     Recently, the demand for batteries is increasing due to an increase in the demand for portable electronic devices.

     One research subject in the field of batteries is improvement of safety. Lithium-ion batteries, which are commonly used in portable electronic devices, may cause accidents such as fire and explosion due to various factors such as an internal short, exceeding the allowed current (or voltage) during charging, temperature rise, and external shock. 
     In the related art, in order to prevent the above-mentioned accidents, in the active material (a positive active material or a negative active material) applied to an electrode plate (a positive electrode substrate or a negative electrode substrate), the active material in facing region (hereinafter, a “facing region”) facing a tab (a positive electrode tab or a negative electrode tab) is removed.

       FIG.  2    is a plan view illustrating one surface of a positive electrode substrate or a negative electrode substrate according to an embodiment in an unwound state. 
     Referring to  FIG.  2   , each of the positive electrode substrate  112  and the negative electrode substrate  114  according to an embodiment may be of a normal type in which an active material  220  (e.g., a positive active material or a negative active material) is not applied to an end of the substrate  210  (e.g., the positive electrode substrate  112  or the negative electrode substrate  114 ) provided with an electrode tab  230  (e.g., the positive electrode tab  121  or the negative electrode tab  123 ). 
     For example,  FIG.  2    may be a plan view illustrating one surface of the positive electrode substrate  112 . 
     According to an embodiment, the positive electrode tab  230  may be attached to one end of the positive electrode substrate  210 , and the positive active material  220  may not be applied around the region to which the positive electrode tab  230  is attached. For example, a positive uncoated region to which the positive active material  220  is not applied may be provided at each end of the positive electrode substrate  210 . Accordingly, the positive active material  220  may not be applied to one end of the positive electrode substrate  210  to which the positive electrode tab  230  is attached. 
     According to an embodiment, the electrode assembly  110  in which the positive electrode substrate  210 , the separator, and the negative electrode substrate  114  are stacked may be wound k times (k is an integer) from the central region  101  of the battery  100 , and may include first to k th  turn regions T 1  to Tk depending on the number of windings. For example, the first turn region T 1  may be a region in which the electrode assembly  110  is first wound to form a first turn, the second turn region T 2  may be a region in which the electrode assembly  110  forms the second turn while enclosing the periphery of the first turn region T 2 , and the k th  region Tk may be a region in which the electrode assembly  110  forms the k th  turn while being wound last. In  FIG.  2   , the dotted lines indicated in the vertical direction may indicate regions where the electrode assembly  110  is bent while being wound. 
     Referring to  FIG.  2   , the positive electrode substrate  210  according to an embodiment may be provided with a positive uncoated region to correspond to the first turn region of the electrode assembly  110 , and a positive uncoated region may be provided to correspond to at least a portion of the k th  turn region of the electrode assembly  110 . 
       FIG.  2    may be a plan view illustrating one surface of the negative electrode substrate  114 . 
     According to an embodiment, the negative electrode tab  230  may be attached to one end of the negative electrode substrate  210 , and the negative active material  220  may not be applied around the region to which the negative electrode tab  230  is attached. For example, a negative uncoated region to which the negative active material  220  is not applied may be provided at each end of the negative electrode substrate  210 . Accordingly, the negative active material  220  may not be applied to one end of the negative electrode substrate  210  to which the negative electrode tab  230  is attached. 
     According to an embodiment, like the positive electrode substrate  112 , the negative electrode substrate  210  may be provided with a negative uncoated region to correspond to the first turn region of the electrode assembly  110 , and a negative uncoated region may be provided to correspond to at least a portion of the k th  turn region of the electrode assembly  110 . 
     In general, when the battery  100  receives an external shock or is charged abnormally, a short circuit phenomenon may occur in at least some regions, and when a short circuit occurs, large current unintended during design may flow. When large current flows through the positive electrode tab  121 , the temperature of the positive electrode tab  121  may increase, and the separator  116  around the positive electrode tab  121  may be contracted or deformed by the heat of the positive electrode tab  121 . In addition, since the positive electrode tab  121  or the negative electrode tab  123  forms a step in the substrate, when an external shock or external pressure is applied, deformation such as tearing of the separator  116  may occur. When the separator  116  is contracted or deformed, at least a portion of the positive electrode substrate  112  and at least a portion of the negative electrode substrate  114  may be short-circuited. When the positive electrode tab  121  and the negative active material are in contact with each other, a safety accident in which the battery  100  ignites or explodes due to a rapid increase in current may occur. According to various embodiments of the disclosure, in order to prevent ignition or explosion of the battery  100  due to the above problem, in the state in which the electrode assembly  110  is wound, the negative uncoated region and the positive electrode tab  121  may be disposed to overlap each other, and the positive uncoated region and the negative electrode tab  123  may be disposed to overlap each other. 
     According to various embodiments of the disclosure, since the negative uncoated region and the positive electrode tab  121  are disposed to overlap each other, even if the peripheral separator is deformed due to heat generated from the positive electrode tab  121  or the step occurring due to the positive electrode tab  121 , the positive electrode tab  121  is brought into contact with the negative uncoated region rather than the negative active material, which may make it possible to prevent ignition or explosion of the battery  100 . According to various embodiments of the disclosure, since the positive uncoated region overlaps the negative electrode tab, even if deformation such as tearing of the separator due to the step occurring due to the negative electrode tab, the negative electrode tab is brought into contact with the positive uncoated region rather than the positive active material, which may make it possible to prevent ignition or explosion of the battery  100 . 
       FIG.  3    is a plan view of a positive electrode substrate or a negative electrode substrate according to another embodiment. 
     Referring to  FIG.  3   , each of the positive electrode substrate  112  and the negative electrode substrate  114  according to another embodiment may be of an expanded type in which an active material  320  (a positive active material or a negative active material) is applied up to an end of the substrate  310  (the positive electrode substrate  112  or the negative electrode substrate  114 ) provided with an electrode tab  330  (the positive electrode tab  121  or the negative electrode tab  123 ). In the battery  100  in which the positive electrode substrate  112  or the negative electrode substrate  114  is configured in an expanded type, the active material application area increases, and thus, the charging capacity may increase compared to the normal type illustrated in  FIG.  2   . 
     For example,  FIG.  3    may be a plan view illustrating one surface of the positive electrode substrate  112  or the negative electrode substrate  114 . 
     According to various embodiments, the positive active material  320  is applied to one end of the positive electrode substrate  310  to which the positive electrode tab  330  is attached, wherein an attachment region to which the positive electrode tab  330  is attached, the region  311  surrounding the attachment region, and a region  312   a  overlapping or facing the negative electrode tab may be a positive uncoated region on which the positive active material  320  is not applied. For example, the first turn region T 1  to which the positive electrode tab  330  is attached may be divided into a positive uncoated region to which the positive electrode tab  330  is attached and the positive active material  320  is not applied, and a positive active material region to which the positive active material  320  is applied. 
     According to various embodiments, the positive uncoated regions  311  and  312   a  in the first turn region T 1  may include a tab-peripheral region  311  disposed to surround the region to which the positive electrode tab  330  is attached, and a first region  312   a  disposed to overlap or face the negative electrode tab when the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) is wound. According to an embodiment, the width W 2  of each of the tab-peripheral region  311  and the first region  312   a  in the longitudinal direction (the X direction in the drawing) of the positive electrode substrate  112  may be greater than the width W 1  of the positive electrode tab  330  or the negative electrode tab. Alternatively, the height H 1  of each of the tab-peripheral region  311  and the first region  312   a  in the width direction (the Y direction in the drawing) of the positive electrode substrate  112  may be smaller than the height H 2  of the second region  312   b  which is adjacent to the first region  312   a  in the width direction and to which the positive active material is applied. For example, the first region  312   a  is a positive uncoated region that overlaps or faces the negative electrode tab when the electrode assembly  110  is wound, wherein the first region  312   a  may have a second width W 2  greater than the first width W 1  of the negative electrode tab and a first height H 1  in the width direction of the positive electrode substrate  112 . The tab-peripheral region  311  is a positive uncoated region, which is located in a region to which the positive electrode tab  330  is attached, and may have a width W 2  and height H 1  which are equal or similar to those of the first region  312   a.  The second region  312   b  is a positive active material region to which a positive active material is applied, wherein the second region  312   b  may be located adjacent to the first region  312   a  in the width direction of the positive electrode substrate  112  and may have a second width W 2  equal to that of the first region  312   a  and a second height H 2  greater than the first height H 1  of the first region  312   a.  Alternatively, the first height H 1  may be greater than the second height H 2 . 
     According to an embodiment, the combined area of all the positive active material regions in the first turn region T 1  may be greater than the combined area of all the positive uncoated regions  311  and  312   a.  Therefore, this embodiment of the disclosure may increase the charging capacity of the battery. 
       FIG.  3    may also be a plan view illustrating one surface of the negative electrode substrate  114 . 
     Like the positive active material, the negative active material  320  according to various embodiments may be applied up to one end of the negative electrode substrate  310  to which the negative electrode tab  330  is attached. However, the attachment region to which the negative electrode tab  330  is attached and the region  311  surrounding the attachment region may be negative uncoated regions to which the negative active material  320  is not applied. For example, the first turn region T 1  to which the negative electrode tab  330  is attached may be divided into a negative uncoated region  311  to which the negative electrode tab  330  is attached and the negative active material  320  is not applied, and a negative active material region to which the negative active material  320  is applied. 
     According to various embodiments, the negative uncoated regions  311  and  312   a  in the first turn region T 1  may include a tab-peripheral region  311  disposed to surround the region to which the negative electrode tab  330  is attached, and a first region  312   a  disposed to overlap or face the positive electrode tab when the electrode assembly  110  is wound. According to an embodiment, the width W 2  of each of the tab-peripheral region  311  and the first region  312   a  in the longitudinal direction (the X direction in the drawing) of the negative electrode substrate  112  may be greater than the width W 1  of the positive electrode tab  330  or the positive electrode tab. Alternatively, the height H 1  of each of the tab-peripheral region  311  and the first region  312   a  in the width direction (the Y direction in the drawing) of the negative electrode substrate  112  may be smaller than the height H 2  of the second region  312   b  which is adjacent to the first region  312   a  in the width direction and to which the negative active material is applied. For example, the first region  312   a  is a negative uncoated region that overlaps or faces the positive electrode tab when the electrode assembly  110  is wound, wherein the first region  312   a  may have a second width W 2  greater than the first width W 1  of the positive electrode tab and a first height H 1  in the width direction of the negative electrode substrate  112 . The tab-peripheral region  311  is a negative uncoated region, which is located in a region to which the negative electrode tab  330  is attached, and may have a width W 2  and height H 1  which are equal or similar to those of the first region  312   a.  The second region  312   b  is a negative active material region to which a negative active material is applied, wherein the second region  312   b  may be located adjacent to the first region  312   a  in the width direction of the negative electrode substrate  112  and may have a second width W 2  equal to that of the first region  312   a  and a second height H 2  greater than the first height H 1  of the first region  312   a.  Alternatively, the first height H 1  may be greater than the second height H 2 . 
     According to an embodiment, the combined area of all the negative active material regions in the first turn region T 1  may be greater than the combined area of all the negative uncoated regions  311  and  312   a.  Therefore, this embodiment of the disclosure may increase the charging capacity of the battery. 
       FIG.  4 A  is a cross-sectional view of a battery in a region to which a positive electrode tab and a negative electrode tab according to an embodiment are attached. For example,  FIG.  4 A  may be a cross-sectional view of the battery  100  taken along line A-A′ in  FIG.  1 A . 
     Referring to  FIG.  4 A , the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) may take a form in which a positive electrode substrate  410 , a separator  430 , and a negative electrode substrate  420  are sequentially wound from the central region  101  of the battery  100 . In the positive electrode substrate  410 , positive active materials  411  and  413  may include a first positive active material  411  applied to the inner peripheral surface of the positive electrode substrate  410  and a second positive active material  413  applied to the outer peripheral surface of the positive electrode substrate  410 . In the negative electrode substrate  420 , negative active materials  421  and  423  may include a first negative active material  421  applied to the inner peripheral surface of the negative electrode substrate  420  and a second negative active material  423  applied to the outer peripheral surface of the negative electrode substrate  420 . 
     According to an embodiment, when wound, the electrode assembly  110  may be divided into a first turn region T 1  forming a first turn, a second turn region T 2  forming a second turn, and a third turn forming third turn region T 3 , . . . , a k th  turn region Tk forming a k th  turn. When viewed in a cross-section in a state in which the electrode assembly  110  is wound, each of the turn regions T 1  to Tk may be divided into an upper region and a lower region. For example, when viewed in the cross-section, the first turn region T 1  may be divided into a first turn upper region T 1 _U disposed at a relatively upper side and a first turn lower region T 1 _L disposed at a relatively lower side. When viewed in the cross-section, the second turn region T 2  may be divided into a second turn upper region T 2 _U disposed at a relatively upper side and a second turn lower region T 2 _L disposed at a relatively lower side. When viewed in the cross-section, the third turn region T 3  may be divided into a third turn upper region T 3 _U disposed at a relatively upper side and a third turn lower region T 3 _L disposed at a relatively lower side, and the regions subsequent to the third turn region T 3  may also be similar to the above-described example. 
     According to an embodiment, when the winding of the electrode assembly  110  starts from the first turn lower region T 1 _L, the first turn upper region T 1 _U may be bent from one side to be connected to the second turn lower region T 2 _L, the second turn upper region T 2 _U may also be bent at the one side to be connected to the third turn lower region T 3 _L, and the fourth turn upper region T 4 _U and the subsequent turn upper regions may also be similar to the above-described example. Alternatively, when the winding of the electrode assembly  110  starts from the first turn upper region T 1 _U, the first turn lower region T 1 _L may be bent from one side to be connected to the second turn upper region T 2 _U, the second turn lower region T 2 _L may also be bent at the one side to be connected to the third turn upper region T 3 _U, and the fourth turn lower region T 4 _L and the subsequent turn lower regions may also be similar to the above-described example. In the illustrated example, the winding of the electrode assembly  110  starts from the first turn lower region T 1 _L, but may not be limited thereto. 
     According to an embodiment, a positive electrode tab  415  may be attached to the positive electrode substrate  410 , and an insulating tape  417  may be attached on the positive electrode tab  415 . The insulating tape  417  may insulate the positive electrode tab  415 , and may prevent the positive electrode tab  415  from coming into direct contact with the separator  430  which might deform or damage the separator  430 . 
     According to an embodiment, a negative electrode tab  425  may be attached to the negative electrode substrate  420 , and an insulating tape  427  may be attached on the negative electrode tab  425 . The insulating tape  427  may insulate the negative electrode tab  425 , and may prevent the negative electrode tab  425  from coming into direct contact with the separator  430  which might deform or damage the separator  430 . 
     According to an embodiment, the facing portion or overlapping portion of the positive electrode tab  415  or the negative electrode tab  425  when the electrode assembly  110  is wound, the negative uncoated regions  429   a  and  429   b  or the positive uncoated regions  419   a  and  419   b  may be provided. According to an embodiment, an insulating layer  440  may be disposed in at least one of the negative uncoated regions  429   a  and  429   b  and the positive uncoated regions  419   a  and  419   b.    
     According to an embodiment, the positive electrode tab  415  may be disposed on the outer peripheral surface of the positive electrode substrate  410  in the first turn upper region T 1 _U. For example, when the positive electrode tab  415  is disposed on the outer peripheral surface of the positive electrode substrate  410  in the first turn upper region T 1 _U, the positive electrode tab  415  may face the inner peripheral surface of the negative electrode substrate  420  disposed in the second turn upper region T 2 _U. In an embodiment, in the second turn upper region T 2 _U, the inner peripheral surface of the negative electrode substrate  420  may be provided with a negative uncoated region  429   b  to face the positive electrode tab  415 . For example, the negative uncoated region  429   b  provided on the inner peripheral surface of the negative electrode substrate  420  in the second turn upper region T 2 _U may be the first region  312   a  illustrated in  FIG.  3   . Alternatively, in the second turn lower region T 2 _L, the outer peripheral surface of the negative electrode substrate  420  may be provided with a negative uncoated region  429   a  to overlap the negative electrode tab  425 . According to various embodiments, the areas of the negative uncoated regions  429   a  and  429   b  may be equal to the area of the positive electrode tab  415  (or the negative electrode tab  425 ) or greater than the area of the positive electrode tab  415  (or the negative electrode tab  425 ). 
     According to an embodiment, in the second turn lower region T 2 _L, the negative electrode tab  425  may be disposed on the inner peripheral surface of the negative electrode substrate  420 . For example, when the negative electrode tab  425  is disposed on the inner peripheral surface of the negative electrode substrate  420  in the second turn lower region T 2 _L, the negative electrode tab  425  may face the outer peripheral surface of the positive electrode substrate  410  disposed in the first turn lower region T 1 _L and may overlap the inner peripheral surface of the positive electrode substrate  410  disposed in the second turn lower region T 2 _L. According to an embodiment, the outer peripheral surface of the positive electrode substrate  410  disposed in the first turn lower region T 1 _L and the inner peripheral surface of the positive electrode substrate  410  disposed in the second turn lower region T 2 _L may be provided with positive uncoated regions  419   a  and  419   b  to overlap the negative electrode tab  425 . According to various embodiments, the areas of the positive uncoated regions  419   a  and  419   b  may be equal to the area of the negative electrode tab  425  or greater than the area of the negative electrode tab  425 . 
     According to an embodiment, in a first portion  450 , the negative electrode substrate  420 , the first negative active material  421 , the separator  430 , the second positive active material  413 , and the positive electrode substrate  410  may be sequentially stacked. In an embodiment, the negative uncoated region  429   b  (e.g., the first region  312   a  of  FIG.  3   ) to which the first negative active material  421  is not applied may be aligned with the positive electrode tab  415  on the positive electrode substrate  410 . 
     According to an embodiment, in an extension  460 , the negative electrode substrate  420 , the second negative active material  423 , and the first positive active material  411  may extend along the separator  430 , which extends toward the first portion  450 , to overlap the first portion  450 . In an embodiment, when the extension  460  extends along the separator  430 , which extends toward the first portion  450 , a second portion  470  may be disposed to overlap the first portion  450 . In this case, in the first portion  450  and the second portion  470 , the negative electrode substrate  420 , the first negative active material  421 , the separator  430 , the second positive active material  413 , the positive electrode substrate  410 , the first positive active material  411 , the separator  430 , the second negative active material  423 , and the negative electrode substrate  420  may be sequentially stacked. In addition, in the first portion  450  and the second portion  470  disposed to face each other, the negative uncoated region  429   b,  the positive electrode tab  415 , the positive uncoated region  419   b,  and the negative uncoated region  429   a  may be aligned with each other. 
       FIG.  4 B  is an enlarged cross-sectional view of a portion of a region to which a positive electrode tab and a negative electrode tab according to an embodiment are attached in a battery. In an embodiment,  FIG.  4 B  may be an enlarged view of the first portion  450  of  FIG.  4 A . 
     According to an embodiment, the first portion  450  may include at least one of a negative electrode substrate  420 , a first negative active material  421 , a separator  430 , an insulating tape  417 , a second positive active material  413 , and a positive electrode substrate  410 . For example, in the first portion  450 , the negative electrode substrate  420 , the first negative active material  421 , the separator  430 , the second positive active material  413 , and the positive electrode substrate  410  may be stacked in a direction substantially parallel to the x-axis direction. In various embodiments, the insulating tape  417  may be replaced with an insulative material, an insulating member, or the like. 
     According to an embodiment, the negative electrode substrate  420  may be provided with a negative uncoated region  429   b  (the first region) to which the first negative active material  421  is not applied. In an embodiment, in the negative electrode substrate  420 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  may include a first insulating layer  441  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.  In an embodiment, the first insulating layer  441  may be disposed from the negative uncoated region  429   b  up to a peripheral region within a predetermined range from the negative uncoated region  429   b  (e.g., a partial region to which the first negative active material  421  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the negative electrode substrate  420  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the negative uncoated region  429   b  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the negative uncoated region  429   b  between the negative electrode substrate  420  and the peripheral region. In addition, the first insulating layer  441  may have a thickness equal or similar to the thickness of the region other than the peripheral region (e.g., the region to which the negative active material  421  is applied), thereby allowing pressure to be uniformly transferred in the process of manufacturing the battery (e.g., the battery  100  in  FIG.  1 A ), suppressing an increase in local resistance generated in the negative uncoated region  429   b,  and preventing swelling of the battery  100 . 
     According to an embodiment, the positive electrode substrate  410  may include a positive electrode tab  415 . In an embodiment, the positive electrode tab  415  may be aligned with the negative uncoated region  429   b  in the z-axis direction.

     According to an embodiment, the negative uncoated region  429   b  (first region) to which the first negative active material  421  is not applied may be provided on the negative electrode substrate  420  of the first portion  450 . In an embodiment, in the negative electrode substrate  420  of the first portion  450 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  of the first portion  450  may include a first insulating layer  441  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.  In an embodiment, the first insulating layer  441  may be disposed from the negative uncoated region  429   b  up to a peripheral region within a predetermined range from the negative uncoated region  429   b  (e.g., a partial region to which the first negative active material  421  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the negative electrode substrate  420  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the negative uncoated region  429   b  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the negative uncoated region  429   b  between the negative electrode substrate  420  and the peripheral region. 
     According to an embodiment, the negative uncoated region  429   a  (first region) to which the second negative active material  423  is not applied may be provided on the negative electrode substrate  420  of the second portion  470 . In an embodiment, in the negative electrode substrate  420  of the second portion  470 , due to the negative uncoated region  429   a,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the second negative active material  423 ) difference may occur in the z-axis direction between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  and to which the second negative active material  423  is applied. 
     According to an embodiment, the negative electrode substrate  420  of the second portion  470  may include a first insulating layer  441  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   a.  In an embodiment, the first insulating layer  441  may be disposed from the negative uncoated region  429   a  up to a peripheral region within a predetermined range from the negative uncoated region  429   a  (e.g., a partial region to which the second negative active material  423  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the negative electrode substrate  420  in the −z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the −z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the negative uncoated region  429   a  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the negative uncoated region  429   a  between the negative electrode substrate  420  and the peripheral region.

For example, when applied to a battery having a spec-type structure, the overlapping portion  480  of  FIG.  4 C  may be disposed substantially horizontally from one side to the other side of the battery having the spec-type structure, corresponding to the shape of the spec-type structure.

In an embodiment, in the negative electrode substrate  420  of the first portion  450 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  of the first portion  450  may include a second insulating layer  442  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.  In an embodiment, the second insulating layer  442  may be disposed in the negative uncoated region  429   b.  For example, the second insulating layer  442  may be in contact with the negative electrode substrate  420  in the z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the first negative active material  421  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   b.  In addition, the second insulating layer  442  may have a thickness equal or similar to the thickness of the region to which the negative active material  421  is applied, thereby allowing pressure to be uniformly transferred in the process of manufacturing the battery (e.g., the battery  100  in  FIG.  1 A ), suppressing an increase in local resistance generated in the negative uncoated region  429   b,  and preventing swelling of the battery  100 . 
     According to an embodiment, the positive electrode substrate  410  may be provided with a negative uncoated region  419   b  (the third region) to which the first positive active material  411  is not applied. In an embodiment, in the positive electrode substrate  410 , due to the positive uncoated region  419   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first positive active material  411 ) difference may occur in the z-axis direction between the positive uncoated region  419   b  and the region which surrounds the positive uncoated region  419   b  and to which the first positive active material  411  is applied. 
     According to an embodiment, the positive electrode substrate  410  may include a first insulating layer  441  in order to compensate for the thickness difference occurring due to the positive uncoated region  419   b.  In an embodiment, the first insulating layer  441  may be disposed from the positive uncoated region  419   b  up to a peripheral region within a predetermined range from the positive uncoated region  419   b  (e.g., a partial region to which the first positive active material  411  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the positive electrode substrate  410  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the positive uncoated region  419   b  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the positive uncoated region  419   b  between the positive electrode substrate  410  and the peripheral region. In addition, the first insulating layer  441  may have a thickness equal or similar to the thickness of the region other than the peripheral region (e.g., the region to which the negative active material  421  is applied), thereby allowing pressure to be uniformly transferred in the process of manufacturing the battery (e.g., the battery  100  in  FIG.  1 A ), suppressing an increase in local resistance generated in the negative uncoated region  429   b,  and preventing swelling of the battery  100 . 
     According to an embodiment, the negative uncoated region  429   a  (a first region) to which the second negative active material  423  is not applied may be provided on the negative electrode substrate  420  of the second portion  470 . In an embodiment, in the negative electrode substrate  420  of the second portion  470 , due to the negative uncoated region  429   a,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the second negative active material  423 ) difference may occur in the z-axis direction between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  and to which the second negative active material  423  is applied.

For example, the first insulating layer  441  may be in contact with the negative electrode substrate  420  in the z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the second negative active material  423  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   a.  In an embodiment, the second insulating layer  442  disposed on the negative electrode substrate  420  of the second portion  470  may be disposed to be symmetrical with the second insulating layer  442  disposed on the negative electrode substrate  420  of the first portion  450 . 
     According to an embodiment, the positive electrode substrate  410  may include a positive electrode tab  415 .

For example, when applied to a battery having a spec-type structure, the overlapping portion  480  of  FIG.  4 D  may be disposed substantially horizontally from one side to the other side of the battery having the spec-type structure, corresponding to the shape of the spec-type structure. 
       FIG.  4 E  is an enlarged cross-sectional view of a portion of a region to which a positive electrode tab and a negative electrode tab according to an embodiment are attached in a battery. In an embodiment,  FIG.  4 E  may be a view illustrating the overlapping structure of the first portion  450  and the second portion  470  extending toward the first portion  450  in  FIG.  4 A . 
     According to an embodiment, the overlapping portion  480  may include an overlapping structure of the first portion  450  and the second portion  470 .

For example, in the overlapping portion  480 , the negative electrode substrate  420 , the first negative active material  421 , the separator  430 , the insulating tape  417 , the second positive active material  413 , the positive electrode substrate  410 , the first positive active material  411 , the separator  430 , the second negative active material  423 , and the negative electrode substrate  420  may be stacked in a direction substantially parallel to the x-axis direction. 
     According to an embodiment, the negative uncoated region  429   b  (a first region) to which the first negative active material  421  is not applied may be provided on the negative electrode substrate  420  of the first portion  450 . In an embodiment, in the negative electrode substrate  420  of the first portion  450 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  of the first portion  450  may include at least one of a second insulating layer  442  and a third insulating layer  443  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.

For example, the second insulating layer  442  may be in contact with the negative electrode substrate  420  in the z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the first negative active material  421  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   b.  In addition, the second insulating layer  442  may have a thickness equal or similar to the thickness of the region to which the negative active material  421  is applied, thereby allowing pressure to be uniformly transferred in the process of manufacturing the battery (e.g., the battery  100  in  FIG.  1 A ), suppressing an increase in local resistance generated in the negative uncoated region  429   b,  and preventing swelling of the battery  100 . 
     In an embodiment, the third insulating layer  443  may be disposed from the negative uncoated region  429   b  up to a peripheral region within a predetermined range from the negative uncoated region  429   b  (e.g., a partial region to which the first negative active material  421  is applied). For example, a portion (e.g., the central portion) of the third insulating layer  443  may be in contact with the second insulating layer  442  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the third insulating layer  443  may be in contact with the peripheral region in the z-axis direction. In this case, the third insulating layer  443  may fill a gap between the second insulating layer  442  and the peripheral region. In addition, the second insulating layer  443  may have a thickness equal or similar to the thickness of the region other than the peripheral region (e.g., the region to which the negative active material  421  is applied), thereby allowing pressure to be uniformly transferred in the process of manufacturing the battery (e.g., the battery  100  in  FIG.  1 A ), suppressing an increase in local resistance generated in the negative uncoated region  429   b,  and preventing swelling of the battery  100 . 
     According to an embodiment, the positive electrode substrate  410  may be provided with a negative uncoated region  419   b  (the third region) to which the first positive active material  411  is not applied. In an embodiment, in the positive electrode substrate  410 , due to the positive uncoated region  419   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first positive active material  411 ) difference may occur in the z-axis direction between the positive uncoated region  419   b  and the region which surrounds the positive uncoated region  419   b  and to which the first positive active material  411  is applied. 
     According to an embodiment, the positive electrode substrate  410  may include a first insulating layer  441  in order to compensate for the thickness difference occurring due to the positive uncoated region  419   b.  In an embodiment, the first insulating layer  441  may be disposed from the positive uncoated region  419   b  up to a peripheral region within a predetermined range from the positive uncoated region  419   b  (e.g., a partial region to which the first positive active material  411  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the positive electrode substrate  410  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the negative uncoated region  429   b  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the negative uncoated region  429   b  between the negative electrode substrate  420  and the peripheral region. 
     According to an embodiment, the negative uncoated region  429   a  (a first region) to which the second negative active material  423  is not applied may be provided on the negative electrode substrate  420  of the second portion  470 . In an embodiment, in the negative electrode substrate  420  of the second portion  470 , due to the negative uncoated region  429   a,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the second negative active material  423 ) difference may occur in the z-axis direction between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  and to which the second negative active material  423  is applied. 
     According to an embodiment, the negative electrode substrate  420  of the second portion  470  may include at least one of a second insulating layer  442  and a third insulating layer  443  in order to compensate for the thickness difference occurring due to the negative uncoated region  429   a.  In an embodiment, the second insulating layer  442  and the third insulating layer  443  disposed on the negative electrode substrate  420  of the second portion  470  may be disposed to be symmetrical with the second insulating layer  442  and the third insulating layer  443  disposed on the negative electrode substrate  420  of the first portion  450 . 
     In an embodiment, the second insulating layer  442  may be disposed in the negative uncoated region  429   a.  For example, the second insulating layer  442  may be in contact with the negative electrode substrate  420  in the −z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the second negative active material  423  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   a.    
     In an embodiment, the third insulating layer  443  may be disposed from the negative uncoated region  429   a  up to a peripheral region within a predetermined range from the negative uncoated region  429   a  (e.g., a partial region to which the second negative active material  423  is applied). For example, a portion (e.g., the central portion) of the third insulating layer  443  may be in contact with the second insulating layer  442  in the −z-axis direction, and the remaining portion (e.g., the peripheral portion) of the third insulating layer  443  may be in contact with the peripheral region in the −z-axis direction. In this case, the third insulating layer  443  may fill a gap between the second insulating layer  442  and the peripheral region. 
     According to an embodiment, the positive electrode substrate  410  may include a positive electrode tab  415 . In an embodiment, the positive electrode tab  415  may be aligned with the negative uncoated regions  429   a  and  429   b  and the positive uncoated region  419   b  in the z-axis direction. 
     According to various embodiments, the overlapping portion  480  of  FIG.  4 E  may be included not only in a jelly-roll type battery (e.g., the battery  100  of  FIG.  1 A or  1 B ) illustrated in  FIG.  4 A , but also in any type of battery to which the overlapping portion  480  is applicable (e.g., a spec-type structure). For example, when applied to a battery having a spec-type structure, the overlapping portion  480  of  FIG.  4 E  may be disposed substantially horizontally from one side to the other side of the battery having the spec-type structure, corresponding to the shape of the spec-type structure. 
       FIG.  5    is a cross-sectional view of a battery in a region to which a positive electrode tab and a negative electrode tab according to an exemplary embodiment are not attached. For example,  FIG.  5    may be a cross-sectional view of the battery  100  taken along line B-B′ in  FIG.  1 A . 
     Referring to  FIG.  5   , in the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to an embodiment, except for a partial region to which a positive electrode tab  415  and a negative electrode tab  425  are attached, negative active materials  421  and  423  or positive active materials  411  and  413  may be applied, as illustrated in  FIG.  3   . 
     For example, as illustrated in  FIG.  4 A , when the positive electrode tab  415  is disposed on the outer peripheral surface of the positive electrode substrate  410  in the first turn upper region T 1 _U, a negative active material  421  may be applied to the inner peripheral surface of the negative electrode substrate  420  disposed in the second turn upper region T 2 _U and facing the positive electrode tab  415 , except for a partial region overlapping the positive electrode tab  415 . 
     Alternatively, as illustrated in  FIG.  4 A , when the negative electrode tab  425  is disposed on the inner peripheral surface of the negative electrode substrate  420  in the second turn lower region T 2 _L, negative active materials  411  and  413  may be applied to the outer peripheral surface of the positive electrode substrate  410  disposed in the first turn lower region T 1 _L and the inner peripheral surface of the positive electrode substrate  410  disposed in the second turn lower region T 2 _L, except for a partial region facing or overlapping the negative electrode tab  425 . 
     According to various embodiments of the disclosure, while providing positive uncoated regions  419   a  and  419   b  and negative uncoated regions  429   a  and  429   b  to compensate for a step of the positive electrode tab  415  or the negative electrode tab  425 , the positive uncoated regions  419   a  and  419   b  and the negative uncoated regions  429   a  and  429   b  are arranged only in a partial region that faces or overlaps the positive electrode tab  415  or the negative electrode tab  425 , whereby it is possible to increase an active material application area, and thus to increase the capacity of the battery  100 . In various embodiments, in the uncoated region of the positive electrode tab  415  or the negative electrode tab  425  to which an active material (a positive active material or a negative active material) is not applied, an insulating layer having a thickness that is equal or similar to that of the active material (e.g., the insulating layers  441  to  443  shown in  FIGS.  4 B to  4 E ) may be disposed. In this case, the insulating layers  441  to  443  may allow pressure to be uniformly transferred during the manufacturing process of the battery  100 , suppress an increase in local resistance generated in the negative uncoated region  429   b,  and prevent swelling of the battery  100 . 
       FIG.  6 A  is a view illustrating an arrangement structure of an electrode assembly according to an embodiment. 
     For example, the arrangement structure of the electrode assembly illustrated in  FIG.  6 A  (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) may be of an alignment type in which the negative uncoated regions  429   a  and  429   b  or the positive uncoated regions  419   a  and  419   b  are disposed in a facing portion or an overlapping portion of the positive electrode tab  415  or the negative electrode tab  425  when the assembly  110  is wound, as illustrated in  FIG.  4 A . Hereinafter, an arrangement structure and a stacked structure of the electrode assembly  110  will be described with reference to  FIGS.  4 A and  6 A . 
     Referring to  FIGS.  4 A and  6 A , the arrangement structure of the electrode assembly  110  according to an embodiment may be of a type in which the positions of respective ends of the positive electrode substrate  410  and the negative electrode substrate  420  (e.g., an end  601  of the positive electrode substrate and an end  603  of the negative electrode substrate) do not coincide with each other. For example, the electrode assembly  110  may be previously aligned such that the number of turns of the positive electrode substrate  410  is greater than the number of turns of the negative electrode substrate  420  by one time. For example, the positive electrode substrate  410  may be shifted to one side from the negative electrode substrate  420  by a length corresponding to the first turn region T 1 , and the positive electrode tab  415  may be disposed to the outer peripheral surface of the positive electrode substrate  410  to correspond to the first turn upper region T 1 _U. 
     According to an embodiment of the disclosure, when the positive electrode tab is disposed in the n th  turn region, the negative electrode substrate may be provided with a negative uncoated region overlapping the positive electrode tab in a portion of the (n−1) th  turn region and/or the (n+1) th  turn region of the electrode assembly  110 . Alternatively, when the negative electrode tab is disposed in the m th  turn region, the positive electrode substrate may be provided with a positive uncoated region overlapping the negative electrode tab in a portion of the (m−1) th  turn region and/or the (m+1) th  turn region of the electrode assembly  110 . 
     For example, in a region of the first turn upper region T 1 _U to which the positive electrode tab  415  is attached, and a region of the first turn lower region T 1 _L which overlaps the negative electrode tab  425 , the outer peripheral surface of the positive electrode substrate  410  may be provided with a positive uncoated region  419   a,  and the remaining area may be applied with the second positive active material  413 . According to an embodiment, the inner peripheral surface of the positive electrode substrate  410  may be applied with the first positive active material  411  from the second turn region T 2 . Since the inner peripheral surface of the positive electrode substrate  410  overlaps the negative electrode tab  425  in the second turn lower region T 2 _L, the positive uncoated region  419   b  may be provided in a portion of the second turn lower region T 2 _L, and the remaining region may be applied with the first positive active material  411 . 
     For example, the negative electrode substrate  420  may be disposed to be wound from the region corresponding to the second turn region T 2 , and the negative electrode tab  425  may be attached to the inner peripheral surface to correspond to the second turn lower region T 2 _L. For example, in a region of the second turn lower region T 2 _L to which the negative electrode tab  425  is attached, and a region of the second turn upper region T 2 _U which faces the positive electrode tab  415 , the inner peripheral surface of the negative electrode substrate  420  may be provided with a negative uncoated region  429   b,  and the remaining area may be applied with the first negative active material  421 . In the second turn lower region T 2 _L, the outer peripheral surface of the negative electrode substrate  420  may be provided with the negative uncoated region  429   a  in a partial region overlapping the negative electrode tab  425 , and the remaining region may be applied with the second negative active material  423 . 
       FIG.  6 B  is a view illustrating a portion of an arrangement structure of an electrode assembly according to an embodiment. In an embodiment,  FIG.  6 B  may be a view illustrating the inner peripheral surface of the negative electrode and the outer peripheral surface of the positive electrode of  FIG.  6 A . 
     Referring to  FIG.  6 B , a first arrangement structure  610  according to an embodiment may be of an alignment type in which a positive electrode tab  415  is disposed in a negative uncoated region  429   b  (a first region) when the inner peripheral surface of a negative electrode substrate (e.g., the negative electrode substrate  420  in  FIG.  4 A ) and the outer peripheral surface of a positive electrode substrate (e.g., the positive electrode substrate  410  in  FIG.  4 A ) are wound. For example, the inner peripheral surface of the negative electrode substrate  420  and the outer peripheral surface of the positive electrode substrate  410  wound according to the first arrangement structure  610  may correspond to those of the alignment type illustrated in the first portion  450  of  FIG.  4 A .

For example, the negative uncoated region  429   b  may be provided in the second turn upper region T 2 _U. In an embodiment, in the negative electrode substrate  420 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  may include a first insulating layer  441  (e.g., the first insulating layer  441  in  FIG.  4 B ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.  In an embodiment, the first insulating layer  441  may be disposed from the negative uncoated region  429   b  up to a peripheral region within a predetermined range from the negative uncoated region  429   b  (e.g., a partial region to which the first negative active material  421  is applied). For example, a portion (e.g., the central portion) of the first insulating layer  441  may be in contact with the negative electrode substrate  420  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the first insulating layer  441  may be in contact with the peripheral region in the z-axis direction. In an embodiment, the first insulating layer  441  may be continuously disposed from the negative uncoated region  429   b  to the peripheral region. In this case, the first insulating layer  441  may fill a gap generated by the negative uncoated region  429   b  between the negative electrode substrate  420  and the peripheral region. 
     According to various embodiments, the first arrangement structure  610  may have a structure in which the negative electrode substrate  420  and the positive electrode substrate  410  are arranged oppositely. For example, in the first arrangement structure  610 , a negative electrode tab (e.g., the negative electrode tab  425  in  FIG.  6 A ) may be disposed on the negative electrode substrate  420 , and a positive uncoated region (e.g., the positive uncoated region  419   a  in  FIG.  6 A ) may be disposed on the positive electrode substrate  410 . In various embodiments, a first insulating layer  441  may be disposed in the positive uncoated region  419   a.    
       FIG.  6 C  is a view illustrating a portion of an arrangement structure of an electrode assembly according to an embodiment. In an embodiment,  FIG.  6 C  may be a view illustrating the inner peripheral surface of the negative electrode and the outer peripheral surface of the positive electrode of  FIG.  6 A . 
     Referring to  FIG.  6 C , a second arrangement structure  620  according to an embodiment may be of an alignment type in which a positive electrode tab  415  is disposed in a negative uncoated region  429   b  (a first region) when the inner peripheral surface of a negative electrode substrate (e.g., the negative electrode substrate  420  in  FIG.  4 A ) and the outer peripheral surface of a positive electrode substrate (e.g., the positive electrode substrate  410  in  FIG.  4 A ) are wound. For example, the inner peripheral surface of the negative electrode substrate  420  and the outer peripheral surface of the positive electrode substrate  410  wound according to the second arrangement structure  620  may correspond to those of the alignment type illustrated in the first portion  450  of  FIG.  4 A . 
     According to an embodiment, the negative electrode substrate  420  may include a negative uncoated region  429   b  to which the first negative active material (e.g., the negative active material  421  in  FIG.  4 A ) is not applied. For example, the negative uncoated region  429   b  may be provided in the second turn upper region T 2 _U. In an embodiment, in the negative electrode substrate  420 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  may include a second insulating layer  442  (e.g., the second insulating layer  442  in  FIG.  4 D ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.  In an embodiment, the second insulating layer  442  may be disposed in the negative uncoated region  429   b.  For example, the second insulating layer  442  may be in contact with the negative electrode substrate  420  in the z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the first negative active material  421  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   b.

In various embodiments, a second insulating layer  442  may be disposed in the positive uncoated region  419   a.    
       FIG.  6 D  is a view illustrating a portion of an arrangement structure of an electrode assembly according to an embodiment. In an embodiment,  FIG.  6 D  may be a view illustrating the inner peripheral surface of the negative electrode and the outer peripheral surface of the positive electrode of  FIG.  6 A . 
     Referring to  FIG.  6 D , a third arrangement structure  630  according to an embodiment may be of an alignment type in which a positive electrode tab  415  is disposed in a negative uncoated region  429   b  (a first region) when the inner peripheral surface of a negative electrode substrate (e.g., the negative electrode substrate  420  in  FIG.  4 A ) and the outer peripheral surface of a positive electrode substrate (e.g., the positive electrode substrate  410  in  FIG.  4 A ) are wound. For example, the inner peripheral surface of the negative electrode substrate  420  and the outer peripheral surface of the positive electrode substrate  410  wound according to the third arrangement structure  630  may correspond to those of the alignment type illustrated in the first portion  450  of  FIG.  4 A . 
     According to an embodiment, the negative electrode substrate  420  may include a negative uncoated region  429   b  to which the first negative active material (e.g., the negative active material  421  in  FIG.  4 A ) is not applied. For example, the negative uncoated region  429   b  may be provided in the second turn upper region T 2 _U. In an embodiment, in the negative electrode substrate  420 , due to the negative uncoated region  429   b,  a predetermined thickness (e.g., the thickness corresponding to the thickness of the first negative active material  421 ) difference may occur in the z-axis direction between the negative uncoated region  429   b  and the region which surrounds the negative uncoated region  429   b  and to which the first negative active material  421  is applied. 
     According to an embodiment, the negative electrode substrate  420  may include at least one of a second insulating layer  442  (e.g., the second insulating layer  442  in  FIG.  4 E ) and a third insulating layer  443  (e.g., the third insulating layer  443  in  FIG.  4 E ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   b.    
     In an embodiment, the second insulating layer  442  may be disposed in the negative uncoated region  429   b.  For example, the second insulating layer  442  may be in contact with the negative electrode substrate  420  in the z-axis direction. In an embodiment, the second insulating layer  442  may have a thickness equal or similar to that of the first negative active material  421  in order to compensate for the thickness difference generated in the negative electrode substrate  420  due to the negative uncoated region  429   b.    
     In an embodiment, the third insulating layer  443  may be disposed from the negative uncoated region  429   b  up to a peripheral region within a predetermined range from the negative uncoated region  429   b  (e.g., a partial region to which the first negative active material  421  is applied). For example, a portion (e.g., the central portion) of the third insulating layer  443  may be in contact with the second insulating layer  442  in the z-axis direction, and the remaining portion (e.g., the peripheral portion) of the third insulating layer  443  may be in contact with the peripheral region in the z-axis direction. In this case, the third insulating layer  443  may fill a gap between the second insulating layer  442  and the peripheral region. 
     According to various embodiments, the third arrangement structure  630  may have a structure in which the negative electrode substrate  420  and the positive electrode substrate  410  are arranged oppositely. For example, in the third arrangement structure  630 , a negative electrode tab (e.g., the negative electrode tab  425  in  FIG.  6 A ) may be disposed on the negative electrode substrate  420 , and a positive uncoated region (e.g., the positive uncoated region  419   a  in  FIG.  6 A ) may be disposed on the positive electrode substrate  410 . In various embodiments, at least one of a second insulating layer  442  and a third insulating layer  443  may be disposed in the positive uncoated region  419   a.    
       FIG.  7    is a cross-sectional view of a battery in a region to which a positive electrode tab and a negative electrode tab according to another embodiment are attached. For example,  FIG.  7    may be a cross-sectional view of the battery  100  taken along line A-A′ in  FIG.  1 A . 
     Referring to  FIG.  7   , unlike the electrode assembly  110  illustrated in  FIG.  4 A , in an electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to another embodiment, the negative electrode substrate  420  may be provided with negative uncoated regions  701  and  703  on the inner and outer peripheral surfaces facing the positive electrode tab  415 . For example, on the inner peripheral surface of the negative electrode substrate  420 , a negative uncoated region  701  may be provided in a portion of the second turn upper region T 2 _U facing the positive electrode tab  415 . On the outer peripheral surface of the negative electrode substrate  420 , a negative uncoated region  703  may be provided in a portion of the second turn upper region T 2 _U facing the positive electrode tab  415 . 
     In various embodiments, in the negative electrode substrate  420 , due to the negative uncoated regions  701  and  703 , a predetermined thickness (e.g., the thickness corresponding to the thicknesses of the negative active materials  421  and  423 ) difference may occur between the negative uncoated regions  701  and  703  and the regions which surround the negative uncoated regions  701  and  703  and to which the negative active materials  421  and  423  are applied. In various embodiments, the negative electrode substrate  420  may include an insulating layer (e.g., the insulating layers  441  to  443  in  FIGS.  4 B to  4 E ) to compensate for the thickness difference occurring due to the negative uncoated regions  701  and  703 . 
       FIG.  8    is a cross-sectional view illustrating an arrangement structure of an electrode assembly according to an embodiment. 
     For example, the arrangement structure of the electrode assembly illustrated in  FIG.  8    (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) may be of an alignment type in which the negative uncoated regions  701  and  703  or the positive uncoated regions  419   a  and  419   b  are disposed in a facing portion or an overlapping portion of the positive electrode tab  415  or the negative electrode tab  425  when the assembly  110  is wound, as illustrated in  FIG.  7   . 
     Unlike the arrangement structure of the electrode assembly  110  illustrated in  FIG.  6 A , the arrangement structure of the electrode assembly  110  illustrated in  FIG.  8    may be provided with a negative uncoated region  803  on the outer peripheral surface, as well as a negative uncoated region  801  (e.g., the negative uncoated region  429   b  in  FIG.  4 A ) on the inner peripheral surface corresponding to the second turn upper region T 2 _U. 
     In various embodiments, in the negative electrode substrate (e.g., the negative electrode substrate  420  in  FIG.  8   ), due to the negative uncoated regions  801  and  803 , a predetermined thickness (e.g., the thickness corresponding to the thicknesses of the negative active materials  421  and  423 ) difference may occur between the negative uncoated regions  801  and  803  and the regions which surround the negative uncoated regions  801  and  803  and to which the negative active materials (e.g., the negative active materials  421  and  423  in  FIG.  8   ) are applied. In various embodiments, the negative electrode substrate  420  may include an insulating layer (e.g., the insulating layers  441  to  443  in  FIGS.  4 B to  4 E ) to compensate for the thickness difference occurring due to the negative uncoated regions  801  and  803 . 
       FIG.  9    is a cross-sectional view of a battery in a region to which a positive electrode tab and a negative electrode tab according to still another embodiment are attached. 
     For example,  FIG.  9    may be a cross-sectional view of the battery  100  taken along line A-A′ in  FIG.  1 A . 
     Referring to  FIG.  9   , unlike the electrode assembly  110  illustrated in  FIG.  4 A , in an electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to another embodiment, one end of the positive electrode substrate  410  to which a positive active material is applied may extend to a region  901  overlapping the positive electrode tab  415 . For example, when the positive electrode tab  415  is disposed in the upper region T 1 _U of the first turn, the pressure due to the step of the positive electrode tab  415  may damage the separator  430  and bring the positive electrode tab  415  and the negative active material  421  above or below the positive electrode tab  415  into direct contact with each other and thus cause ignition or explosion. In an embodiment of the disclosure, since one end of the positive electrode substrate  410  applied with the positive active material extends to a region overlapping the positive electrode tab  415 , even if the separator  430  is damaged due to the step of the positive electrode tab  415 , it is possible to prevent ignition or explosion since the positive electrode tab  415  comes into contact with the positive electrode substrate  410  which has the same polarity as the positive electrode tab  415  and overlaps the lower portion of the positive electrode tab  415 , rather than a negative electrode substrate  410 . 
     In various embodiments, due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ) in the negative electrode substrate  420  (or the positive electrode substrate  410 ), a predetermined thickness (e.g., the thickness corresponding to the thickness of the active material  423  or  411 ) difference may occur between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  (or the positive uncoated region  419   b ) and to which the second negative active material  423  (or the first positive active material  411 ) is applied. In various embodiments, the negative electrode substrate  420  (or the positive electrode substrate  410 ) may include an insulating layer (e.g., the insulating layer  441  to  443  in  FIGS.  4 B to  4 E ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ). 
       FIG.  10    is a view illustrating a modified example of a battery structure according to another embodiment. For example,  FIG.  10    may be a cross-sectional view of the battery  100  taken along line A-A′ in  FIG.  1 A . 
     Referring to  FIG.  10   , unlike the electrode assembly  110  illustrated in  FIG.  9   , in the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to an embodiment of the disclosure, a positive electrode tab  1020  (e.g., the positive electrode tab  415 ) may be attached to the inner peripheral surface of the positive electrode substrate  410 . When the positive electrode tab  1020  is attached to the inner peripheral surface of the positive electrode substrate  410 , the pressure due to the step of the positive electrode tab  1020  may be reduced from the standpoint of the negative electrode substrate  420  located outside (above) the positive electrode tab  1020 . However, since the positive electrode tab  1020  is attached to the inner peripheral surface, the downward pressure of the positive electrode tab  1020  is increased. Thus, in an embodiment of the disclosure, as indicated by reference numeral  1010 , the positive active material (e.g., positive active material  411  or  413 ) may extend up to a region in which one end of the positive electrode substrate  410  and the positive electrode tab  1020  overlap each other. 
     In various embodiments, due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ) in the negative electrode substrate  420  (or the positive electrode substrate  410 ), a predetermined thickness (e.g., the thickness corresponding to the thickness of the active material  423  or  411 ) difference may occur between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  (or the positive uncoated region  419   b ) and to which the second negative active material  423  (or the first positive active material  411 ) is applied. In various embodiments, the negative electrode substrate  420  (or the positive electrode substrate  410 ) may include an insulating layer (e.g., the insulating layer  441  to  443  in  FIGS.  4 B to  4 E ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ). 
       FIG.  11    is a view illustrating another modified example of a battery structure according to another embodiment. For example,  FIG.  11    may be a cross-sectional view of the battery  100  taken along line A-A′ in  FIG.  1 A . 
     Referring to  FIG.  11   , unlike the electrode assembly  110  illustrated in  FIG.  9   , in the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to an embodiment of the disclosure, a positive electrode tab  1120  (e.g., the positive electrode tab  415 ) may be attached to the inner peripheral surface of the positive electrode substrate  410 . When the positive electrode tab  1120  is attached to the inner peripheral surface of the positive electrode substrate  410 , the pressure due to the step of the positive electrode tab  1120  may be reduced from the standpoint of the negative electrode substrate  420  located outside (above) the positive electrode tab  1120 . However, since the positive electrode tab  1120  is attached to the inner peripheral surface, the downward pressure of the positive electrode tab  1120  is increased. Thus, in an embodiment of the disclosure, as indicated by reference numeral  1110 , the inner peripheral surface overlapping the lower portion of the positive electrode tab  415  at one end of the negative electrode substrate  420  may be provided with a negative uncoated region to which a negative active material is applied. For example, when the positive electrode tab  1120  is attached to the inner peripheral surface of the positive electrode substrate  410  in the first turn upper region T 1 _U, the negative uncoated region  1110  may be provided since the end region of the inner peripheral surface of the negative electrode substrate  420  overlaps the lower portion of the positive electrode tab  415  in the first turn lower region T 1  L. However, in the area overlapping the lower portion of the positive electrode tab  415 , a negative active material  423  may be applied to the outer peripheral surface of the negative electrode tab  420 . 
     In various embodiments, due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ) in the negative electrode substrate  420  (or the positive electrode substrate  410 ), a predetermined thickness (e.g., the thickness corresponding to the thickness of the active material  423  or  411 ) difference may occur between the negative uncoated region  429   a  and the region which surrounds the negative uncoated region  429   a  (or the positive uncoated region  419   b ) and to which the second negative active material  423  (or the first positive active material  411 ) is applied. In various embodiments, the negative electrode substrate  420  (or the positive electrode substrate  410 ) may include an insulating layer (e.g., the insulating layer  441  to  443  in  FIGS.  4 B to  4 E ) in order to compensate for the thickness difference occurring due to the negative uncoated region  429   a  (or the positive uncoated region  419   b ). 
       FIG.  12    is a view illustrating a portion of a cross section of a negative electrode substrate or a positive electrode substrate according to an embodiment. 
     Referring to  FIG.  12   , when the battery  100  according to an embodiment of the disclosure is configured in a normal type to be the same as or similar to the example illustrated in  FIG.  2   , an active material  1230  (e.g., the positive active material  411  or  413  or the negative active material  421  or  423 ) may extend to a region in which a substrate  1220  to which an electrode tab  1210  (e.g., the positive electrode tab  121  or the negative electrode tab  123 ) is attached is bent. When the active material  1230  is also applied to the region in which the substrate  1220  is bent, separation of the active material  1230  may be prevented, and the capacity of the battery  100  may be increased. 
       FIG.  13    is a view illustrating an active material application region of a negative electrode substrate or a positive electrode substrate according to an embodiment. For example,  FIG.  13    may be a plan view illustrating the negative electrode substrate or the positive electrode substrate illustrated in  FIG.  12    in an unwound state. 
     Referring to  FIG.  13   , the battery  100  according to an embodiment of the disclosure may be configured in a normal type to be the same as or similar to the example illustrated in  FIG.  2   . For example, a positive electrode tab  1310  (e.g., the positive electrode tab  415 ) may be attached to one end of the substrate, and the first turn region T 1  around the positive electrode tab  1310  may be provided with a positive uncoated region to which a positive active material  1320  (e.g., the positive active material  411  or  413 ) is not applied. According to an embodiment, a partial region of the positive uncoated region may be an overlapping portion  1330  overlapping a negative electrode tab  133 , and unlike the example illustrated in  FIG.  2   , a positive active material  1320  application region may extend to a boundary point between a bending region BA and the overlapping portion  1330 . According to various embodiments, the overlapping portion  1330  may be a region that faces or overlaps the negative electrode tab (e.g., the negative electrode tab  425 ) in the wound state. 
     According to various embodiments, each of the positive electrode substrate  112  and the negative electrode substrate  114 , and the inner and outer peripheral surfaces of each of the substrates  112  and  114  may have structures to which the normal type illustrated in  FIG.  2    or the expansion type as illustrated in  FIG.  3    is selectively applied. The details will be described below. 
     In various embodiments, due to a positive uncoated region (e.g., the positive uncoated region  419   b  in  FIG.  11   ), in the positive electrode substrate (e.g., the positive electrode substrate  410  in  FIG.  11   ), a predetermined thickness (e.g., the thickness corresponding to the positive active material  1320 ) difference may occur between the positive uncoated region and the area to which the positive active material  1320  is applied. In various embodiments, the positive electrode substrate  410  may include an insulating layer (e.g., the insulating layers  441  to  443  in  FIGS.  4 B to  4 E ) to compensate for the thickness difference occurring due to the negative uncoated region  419   b.    
       FIG.  14    is a view illustrating an arrangement structure of an electrode assembly according to a first embodiment. 
     Referring to  FIG.  14   , in the electrode assembly  110  according to the first embodiment, a positive electrode substrate  1410  may be configured in a normal type, and a negative electrode substrate  1420  may be configured in an expansion type. 
     For example, a first positive active material  1411  may be applied to the outer peripheral surface of the positive electrode substrate  1410 , wherein the first positive active material  1411  may be applied only to a portion before the region to which the positive electrode tab  1415  is attached, so that a positive uncoated region may be provided at the end of the outer peripheral surface adjacent to the positive electrode tab  1415 . According to an embodiment, the first positive active material  1411  application region may extend to the bending region BA adjacent to the positive electrode tab  1415 . 
     Alternatively, a second positive active material  1413  may be applied to the inner peripheral surface of the positive electrode substrate  1410 , wherein the second positive active material  1413  may be applied only to a portion before the region to which the positive electrode tab  1415  is attached, so that a positive uncoated region may be provided at the end of the inner peripheral surface adjacent to the positive electrode tab  1415 . According to an embodiment, as indicated by reference numeral  1417 , the inner peripheral surface of the positive electrode substrate  1410  may be provided, in a region overlapping the negative electrode tab  1425 , with a positive uncoated region to which the second positive active material  1413  is not applied. 
     Additionally, the first negative active material  1421  may be applied to the inner peripheral surface of the negative electrode substrate  1420 , wherein the first negative active material  1421  may be applied up to the end of the inner peripheral surface to which the negative electrode tab  1425  is attached. According to an embodiment, around the region to which the negative electrode tab  1425  is attached and in a first region  1427  which overlaps the positive electrode tab  1415  when the electrode assembly  110  is wound, the inner peripheral surface of the negative electrode substrate  1420  may be provided with a negative uncoated region to which the first negative active material  1421  is not applied. 
     Alternatively, a second negative active material  1423  may be applied to the outer peripheral surface of the negative electrode substrate  1420 , wherein the second negative active material  1423  may be applied up to the end of the outer peripheral surface to which the negative electrode tab  1415  is attached. According to an embodiment, the region  1429  overlapping the negative electrode tab  1425  on the outer peripheral surface of the negative electrode substrate  1420  may be provided with a negative uncoated region to which the second negative active material  1423  is not applied. 
     In various embodiments, in the negative electrode substrate (e.g., the negative electrode substrate  420  in FIG. 11 ), due to the negative uncoated region  1427 , a predetermined thickness (e.g., the thickness corresponding to the thickness of the negative active material  421  or  423 ) difference may occur between the negative uncoated region  1427  and the region which surrounds the negative uncoated region  1427  and to which the negative active material (e.g., the negative active material  421  or  423  in  FIG.  11   ) is applied. In various embodiments, the negative electrode substrate  420  may include an insulating layer (e.g., the insulating layers  441  to  443  in  FIGS.  4 B to  4 E ) to compensate for the thickness difference occurring due to the negative uncoated region  1427 . 
       FIG.  15    is a view illustrating an arrangement structure of an electrode assembly according to a second embodiment. 
     Referring to  FIG.  15   , in the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to the second embodiment, a positive electrode substrate  1510  may be configured in a normal type, and a negative electrode substrate  1520  may be configured in a normal type and an expansion type. 
     For example, the structure of the positive electrode substrate  1510  may be similar to that of the positive electrode substrate  1410  illustrated in  FIG.  14   . For example, a first positive active material  1511  may be applied to the outer peripheral surface of the positive electrode substrate  1510 , wherein the first positive active material  1511  may be applied only to a portion before the region to which the positive electrode tab  1515  is attached, so that a positive uncoated region may be provided at the end of the outer peripheral surface adjacent to the positive electrode tab  1515 . According to an embodiment, the first positive active material  1511  application region may extend to a first bending region BA 1  adjacent to the positive electrode tab  1515 . 
     Alternatively, a second positive active material  1513  may be applied to the inner peripheral surface of the positive electrode substrate  1510 , wherein the second positive active material  1513  may be applied only to a portion before the region to which the positive electrode tab  1515  is attached, so that a positive uncoated region may be provided at the end of the inner peripheral surface adjacent to the positive electrode tab  1515 . According to an embodiment, on the inner peripheral surface of the positive electrode substrate  1510 , as indicated by reference numeral  1517 , a positive uncoated region to which the second positive active material  1513  is not applied is provided in a region overlapping the negative electrode tab  1525 . 
     Additionally, a first negative active material  1521  may be applied to the inner peripheral surface of the negative electrode substrate  1520 , wherein the first negative active material  1521  may be applied only to a portion before the region to which the negative electrode tab  1525  is attached, so that a negative uncoated region may be provided at the end of the inner peripheral surface adjacent to the negative electrode tab  1525 . According to an embodiment, the first negative active material  1521  application region may extend to a second bending region BA 2  adjacent to the negative electrode tab  1525 . According to an embodiment, in a first region  1527  which overlaps the positive electrode tab  1515  when the electrode assembly  110  is wound, the inner peripheral surface of the negative electrode substrate  1520  may be provided with a negative uncoated region to which the first negative active material  1521  is not applied. 
     Alternatively, a second negative active material  1523  may be applied to the outer peripheral surface of the negative electrode substrate  1520 , wherein the second negative active material  1523  may be applied up to the end of the outer peripheral surface to which the negative electrode tab  1515  is attached. According to an embodiment, the region  1529  overlapping the negative electrode tab  1525  on the outer peripheral surface of the negative electrode substrate  1520  may be provided with a negative uncoated region to which the second negative active material  1523  is not applied. 
     In various embodiments, in the negative electrode substrate (e.g., the negative electrode substrate  420  in FIG. 11 ), due to the negative uncoated region  1527 , a predetermined thickness (e.g., the thickness corresponding to the thickness of the negative active material  421  or  423 ) difference may occur between the negative uncoated region  1527  and the region which surrounds the negative uncoated region  1527  and to which the negative active material (e.g., the negative active material  421  or  423  in  FIG.  11   ) is applied. In various embodiments, the negative electrode substrate  420  may include an insulating layer (e.g., the insulating layers  441  to  443  in  FIGS.  4 B to  4 E ) to compensate for the thickness difference occurring due to the negative uncoated region  1527 . 
       FIG.  16    is a view illustrating an arrangement structure of an electrode assembly according to a third embodiment. 
     Referring to  FIG.  16   , in the electrode assembly (e.g., the electrode assembly  110  in  FIG.  1 A  or  FIG.  1 B ) according to an embodiment of the disclosure, the positive electrode substrate  1610  and the negative electrode substrate  1620  may be configured in a normal type. 
     For example, the structure of the positive electrode substrate  1610  may be similar to that of the positive electrode substrate  1410  illustrated in  FIG.  14   .
