The present application provides a battery, a power consumption device, and a method for producing a battery, which could improve safety performance of the battery.

In a first aspect, a battery as defined in claim <NUM> is provided. The battery includes a battery cell, a first wall of the battery cell being provided with a pressure relief mechanism, and the pressure relief mechanism being configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a fire-fighting pipeline configured to accommodate a fire-fighting medium and the fire-fighting pipeline being configured to discharge the fire-fighting medium when the pressure relief mechanism is actuated; a first fixing member, disposed on a side of the fire-fighting pipeline close to the first wall, the first fixing member being provided with a first limiting part and a second limiting part; and a second fixing member, disposed on a side of the fire-fighting pipeline away from the first wall, the second fixing member being provided with a third limiting part and a fourth limiting part, the third limiting part and the first limiting part being matched with each other to fix the fire-fighting pipeline between the first fixing member and the second fixing member, the fourth limiting part and the second limiting part being matched with each other to limit the second fixing member in a first direction, and the first direction being parallel to an extending direction of the fire-fighting pipeline.

For a battery of the present application, a second limiting part is matched with a fourth limiting part to limit sliding of the second fixing member in a direction parallel to a fire-fighting pipeline, and thus the second fixing member is limited. In this way, a first limiting part and a third limiting part are matched with each other, and when the fire-fighting pipeline is fixed between the first fixing member and the second fixing member, it is possible to avoid the first fixing member and the second fixing member being staggered due to the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline. In this way, even if a battery undergoes vibration, under the limiting of the second limiting part and the fourth limiting part, the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline can be avoided. Thus the second fixing member is fitted with the first fixing member to fix the fire-fighting pipeline, which can avoid the fire-fighting pipeline detaching from the original installation position; and when the pressure relief mechanism is actuated, the fire-fighting pipeline can be damaged smoothly and accurately to lower the temperature of emissions discharged through the pressure relief mechanism in time, thereby improving the safety performance of the battery.

The third limiting part includes a buckle extending in the first direction; the fourth limiting part is an opening disposed in the buckle; the first limiting part is a groove matched with the buckle; the second limiting part is a stopper matched with the opening, and when the buckle is buckled into the groove, the stopper is located within the opening to limit movement of the buckle in the first direction.

When the buckle is buckled into the groove, as long as the stopper is located within the opening of the buckle, a limit to the movement of the buckle in the first direction may be achieved, which is convenient for processing and assembly.

In some embodiments, a length of the stopper in a second direction is greater than a thickness of the buckle in the second direction, and the second direction is parallel to the first wall and perpendicular to the first direction.

A length of the stopper in a second direction is set to be greater than a thickness of the buckle in the second direction, and therefore this can avoid a case where the buckle shuns the stopper and slides in the first direction due to the smaller length of the stopper in the second direction when the buckle is buckled into the groove.

In some embodiments, the stopper has a first plane perpendicular to the first direction, and a side wall of the opening is matched with the first plane such that the stopper is located within the opening.

A first plane of the stopper is matched with a side wall of the opening such that the stopper is located within the opening, to limit the movement of the buckle in the first direction, which is convenient for processing and assembly.

In some embodiments, the stopper is a cuboid stopper, and the opening is a rectangular opening matched with the cuboid stopper.

The stopper is set as a cuboid stopper, and the opening is set as a rectangular opening, which have simple structures and are convenient for processing and assembly.

In some embodiments, the stopper is disposed at one end of the groove in the first direction, and/or the groove has two segments in the first direction, and the stopper is disposed in the middle of the two segments of the groove.

The stopper is disposed at one end of the groove, and/or the stopper is disposed in the middle of the two segments of the groove, and when the buckle is buckled into the groove, the stopper is located within an opening of the buckle, so that the sliding of the buckle in the first direction can be limited.

In some embodiments, the third limiting part includes a first buckle and a second buckle, the first buckle and the second buckle are separately disposed in the second direction, and the first limiting part includes a first groove and a second groove, the first groove and the second groove are separately disposed in the second direction, and are matched with the first buckle and the second buckle, respectively.

In this way, the first groove is matched with the first buckle and the second groove is matched with the second buckle, the fire-fighting pipeline is fixed between the first limiting part and the third limiting part, to avoid the fire-fighting pipeline deviating from the pressure relief mechanism in a direction perpendicular to the first wall during the use of the battery, thereby ensuring the relative position of the pressure relief mechanism and the fire-fighting pipeline and ensuring that the fire-fighting pipeline can be damaged accurately and timely when the pressure relief mechanism is actuated, so as to achieve the effect of cooling.

In some embodiments, the stopper corresponding to the first groove and the stopper corresponding to the second groove are axially symmetrically distributed with the first direction as an axis.

In this way, when the first buckle is buckled into the first groove and the second buckle is buckled into the second groove, openings of the first buckle and the second buckle have matched stoppers to limit the sliding of the first buckle in the first groove and the sliding of the second buckle in the second groove, and more effectively limit the sliding of the second fixing member in the first direction.

In some embodiments, the stopper corresponding to the first groove and the stopper corresponding to the second groove are symmetrically distributed about the center.

In this way, when the first limiting part and the third limiting part are installed and matched, if the installation direction is opposite to the original matching direction, the first limiting part cannot be matched and installed with the third limiting part, which can achieve a structurally fool-proof effect.

In some embodiments, a number of the stoppers corresponding to the first groove differs from a number of the stoppers corresponding to the second groove.

In some embodiments, the first fixing member is fixed to a surface of the first wall of the battery cell that is away from an interior of the battery cell.

In this way, when the fire-fighting pipeline is fixed between the first fixing member and the second fixing member, the fire-fighting pipeline is close to the pressure relief mechanism fixed to the first wall of the battery cell, which ensures that the fire-fighting pipeline can be accurately and timely damaged when the pressure relief mechanism is actuated to lower the temperature of emissions discharged through the pressure relief mechanism in time, thereby improving the safety performance of the battery.

In some embodiments, the first fixing member is fixed to a surface of a beam of a box that is close to the fire-fighting pipeline, the box being configured to accommodate the battery cell.

In some embodiments, the first fixing member is provided with a fixing part, and the fixing part is configured to fix the first fixing member to the beam. The first fixing member is fixed to the beam by the fixing member, so as to avoid shaking of the first fixing member in the box due to loose installation.

In some embodiments, the battery includes a plurality of battery cells arranged in the first direction, a plurality of first fixing members arranged in the first direction, and at least one second fixing member.

A plurality of first fixing members are provided to fix the fire-fighting pipeline, so that the fire-fighting pipeline is more stable.

In some embodiments, one second fixing member corresponds to the plurality of first fixing members. In this way, the number of the second fixing members can be reduced, thereby improving the processing and assembly efficiency of the second fixing members.

In a second aspect, a power consumption device as defined in claim <NUM> is provided, including the battery according to the first aspect or any one of the embodiments of the first aspect, and the battery is configured to provide electrical energy.

In a technical solution of an embodiment of the present application, a second limiting part is matched with a fourth limiting part to limit sliding of the second fixing member in a direction parallel to a fire-fighting pipeline, and thus the second fixing member is limited. In this way, a first limiting part and a third limiting part are matched with each other, and when the fire-fighting pipeline is fixed between the first fixing member and the second fixing member, it is possible to avoid the first fixing member and the second fixing member being staggered due to the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline. In this way, even if a battery undergoes vibration, under the limiting of the second limiting part and the fourth limiting part, the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline can be avoided. Thus the second fixing member is fitted with the first fixing member to fix the fire-fighting pipeline, which can avoid the fire-fighting pipeline detaching from the original installation position; and when the pressure relief mechanism is actuated, the fire-fighting pipeline can be damaged smoothly and accurately to lower the temperature of emissions discharged through the pressure relief mechanism in time, thereby improving the safety performance of the battery.

It should be understood that dimensions such as thicknesses, lengths, and widths of various components in embodiments of the present application shown in the drawings, as well as dimensions of the overall thickness, length and width of an integrated apparatus are merely illustrative, and should not constitute any limitation to the present application.

In the present application, a battery cell may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium/lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc., which is not limited by the embodiments of the present application. The battery cell may be cylindrical, flat, cuboid or in another shape, which is not limited by the embodiments of the present application. The battery cell is generally divided into three types according to the way of packaging: a cylindrical battery cell, a prismatic battery cell and a pouch battery cell, which is not limited by the embodiments of the present application.

The battery mentioned in the embodiments of the present application refers to a single physical module that includes one or more battery cells to provide a higher voltage and capacity. For example, the battery mentioned in the present application may include a battery module or a battery pack. The battery generally includes a box for enclosing one or more battery cells. The box can prevent liquid or other foreign matters from affecting the charging or discharging of the battery cell.

The battery cells include an electrode assembly and an electrolyte, and the electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The operation of the battery cell mainly relies on movement of metal ions between the positive electrode sheet and the negative electrode sheet. The positive electrode sheet includes a positive electrode current collector and a positive active material layer. The positive active material layer is coated on a surface of the positive electrode current collector, and the positive electrode current collector not coated with the positive active material layer protrudes from the positive electrode current collector coated with the positive active material layer and is used as a positive electrode tab. A lithium-ion battery is taken as an example, the material of the positive electrode current collector may be aluminum, and the positive electrode active material may be lithium cobalt oxides, lithium iron phosphate, ternary lithium, or lithium manganate, or the like. The negative electrode sheet includes a negative electrode current collector and a negative active material layer. The negative active material layer is coated on a surface of the negative electrode current collector, and the negative current collector not coated with the negative active material layer protrudes from the negative current collector coated with the negative active material layer and is used as a negative electrode tab. The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon or silicon, and like. In order to ensure that a large current is passed without fusing, positive electrode tabs are multiple in number and stacked together, and negative electrode tabs are multiple in number and stacked together. A material of the separator may be polypropylene (PP), polyethylene (PE), or the like. In addition, the electrode assembly may be a winding structure or a laminated structure, and the embodiments of the present application are not limited thereto.

With the development of the battery technology, it is necessary to consider many design factors, such as energy density, cycle life, discharge capacity, C-rate, and other performance parameters. In addition, the safety of the battery should also be considered.

With respect to the battery cell, the main safety hazards come from the charging and discharging processes, and a suitable environmental temperature design is also required. In order to effectively avoid unnecessary losses, multiple protection measures are generally taken for the battery cell. Specifically, the protection measures include at least one or more of a switching element, a properly selected separator material and a pressure relief mechanism. The switching element refers to an element that may stop the charging or discharging of a battery when the temperature or resistance in a battery cell reaches a certain threshold. The separator is configured to isolate the positive electrode sheet from the negative electrode sheet and can automatically dissolve micron-sized (or even nanoscale) micropores attached to the separator when the temperature rises to a certain value, thus preventing metal ions from passing through the separator and terminating the internal reaction of the battery cell. The pressure relief mechanism refers to an element or component that is actuated when an internal pressure or temperature of the battery cell reaches a predetermined threshold to relieve the internal pressure or temperature.

The pressure relief mechanism on the battery cell has an important influence on the safety of the battery. For example, when short circuit, overcharge and other phenomena occur, it may lead to thermal runaway inside the battery cell, resulting in a sudden increase in pressure or temperature. In this case, the internal pressure and temperature can be relieved outward through the actuation of the pressure relief mechanism, to prevent the battery cell from exploding and catching fire.

As for the design of the pressure relief mechanism, the main concern is to relieve the high pressure and high heat inside the battery cell, that is, to discharge the emissions to the outside of the battery cell. The high-temperature and high-pressure emissions are discharged along a direction of the pressure relief mechanism provided in the battery cell, and more specifically, may be discharged along a direction of a region where the pressure relief mechanism is actuated. The strength and destructive power of such emissions may be great, or may even be enough to break through one or more structures along this direction, causing further safety problems.

In view of this, a fire-fighting pipeline can be provided at a corresponding position of the pressure relief mechanism of the battery cell, and emissions discharged from the battery cell when the pressure relief mechanism is actuated are used to pass through and damage the fire-fighting pipeline, so that the fire-fighting medium in the fire-fighting pipeline is discharged from a damaged position of the fire-fighting pipeline, to cool and lower a temperature of the emissions discharged from the pressure relief mechanism, thereby reducing the risk resulting from the emissions and enhancing the safety of the battery.

In order to ensure that the fire-fighting pipeline can be damaged when the pressure relief mechanism is actuated, to lower the temperature of the emissions discharged by the pressure relief mechanism in time, a position of the fire-fighting pipeline should correspond to a position of the pressure relief mechanism. However, during the actual use of the battery, the battery may undergo vibration, and thus how to install and fix the fire-fighting pipeline in the box of the battery is an extremely important issue.

Therefore, according to an embodiment of the present application, a battery is provided, including a plurality of battery cells and a fire-fighting pipeline, a pressure relief mechanism is provided on a first wall of the battery cell, and the battery also includes a first fixing member and a second fixing member. The first fixing member is disposed on a side of the fire-fighting pipeline close to the first wall, and the second fixing member is disposed on a side of the fire-fighting pipeline away from the first wall, and the first fixing member is provided with a first limiting part and a second limiting part, and the second fixing member is provided with a third limiting part and a fourth limiting part. The third limiting part and the first limiting part are matched with each other to fix the fire-fighting pipeline between the first fixing member and the second fixing member, and the fourth limiting part and the second limiting part are matched with each other to limit the second fixing member in a direction parallel to an extending direction of the fire-fighting pipeline. That is, the second limiting part is matched with the fourth limiting part to limit the second fixing member. In this way, the first limiting part and the third limiting part are matched with each other, and when the fire-fighting pipeline is fixed between the first fixing member and the second fixing member, it is possible to avoid the first fixing member and the second fixing member being staggered due to the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline. In this way, even if a battery undergoes vibration, under the limiting of the second limiting part and the fourth limiting part, the sliding of the second fixing member in the direction parallel to the fire-fighting pipeline can be avoided. Thus the second fixing member is fitted with the first fixing member to fix the fire-fighting pipeline, which can avoid the fire-fighting pipeline detaching from the original installation position; and when the pressure relief mechanism is actuated, the fire-fighting pipeline can be damaged smoothly and accurately to lower the temperature of emissions discharged through the pressure relief mechanism in time, thereby improving the safety performance of the battery.

For the convenience of description, the following embodiments take a vehicle as an example of the power consumption device for description.

For example, as shown in <FIG> is a schematic structural diagram of a vehicle <NUM> according to an embodiment of the present application. The vehicle <NUM> may be a fuel-powered vehicle, a gas-powered vehicle, or a new-energy vehicle. The new-energy vehicle may be a battery electric vehicle, a hybrid vehicle, or an extended-range vehicle, or the like. A motor <NUM>, a controller <NUM> and a battery <NUM> may be provided inside the vehicle <NUM>, and the controller <NUM> is configured to control the battery <NUM> to supply power to the motor <NUM>.

That is, a plurality of battery cells may directly form a battery, or may first form battery modules, and then the battery modules form a battery.

For example, <FIG> shows an exploded schematic structural diagram of a battery <NUM> according to an embodiment of the present application. The battery <NUM> may include a plurality of battery cells <NUM> arranged in an array. The battery <NUM> may further include a box <NUM> with the interior thereof being a hollow structure, the plurality of battery cells <NUM> are accommodated in the box <NUM>, and the shape of the box <NUM> may be determined according to the plurality of battery cells <NUM> accommodated therein. In some embodiments, the box may be a cuboid with six walls. <FIG> shows a possible implementation of a box <NUM> of the embodiment of the present application. As shown in <FIG>, the box may include two portions, which are referred to as a first portion <NUM> and a second portion <NUM>, respectively, and the first portion <NUM> and the second portion <NUM> are fastened together. The shapes of the first portion <NUM> and the second portion <NUM> may be determined according to the shape of the battery cell <NUM>, and at least one of the first portion <NUM> and the second portion <NUM> has an opening.

For another example, different from that shown in <FIG>, only one of the first portion <NUM> and the second portion <NUM> may be a hollow cuboid with an opening, while the other may be a plate shape, so as to cover the opening.

The plurality of battery cells <NUM> are combined in parallel connection or series connection or series-parallel connection and are then placed in the box <NUM> formed by fastening the first portion <NUM> to the second portion <NUM>.

Optionally, the battery <NUM> may also include other structures, which will not be described in detail herein. For example, the battery <NUM> may also include a bus component.

Specifically, the bus component may implement an electrical connection between the battery cells <NUM> by connecting electrode terminals of the battery cells <NUM>. Further, the bus component may be fixed to the electrode terminals of the battery cells <NUM> by means of welding. Electric energy of the plurality of battery cells <NUM> may be further led out through an electrically conductive mechanism passing through the box <NUM>.

According to different power requirements, the number of the battery cells <NUM> in the battery <NUM> may be set to any value. The plurality of battery cells <NUM> may be connected in series or in parallel or in series and parallel to implement larger capacity or power. Since the number of battery cells <NUM> included in each battery <NUM> may be large, the battery cells <NUM> may be provided in groups for convenience of installation, and each group of battery cells <NUM> constitutes a battery module. The number of the battery cells <NUM> included in the battery module is not limited and may be set as required. The battery may include a plurality of battery modules, and these battery modules may be connected in series, in parallel or in series and parallel.

<FIG> shows a partially exploded schematic structural diagram of a battery <NUM> according to an embodiment of the present application, and <FIG> shows a partial schematic top view of the battery <NUM> corresponding to <FIG>. As shown in <FIG> and <FIG>, the battery <NUM> of the embodiment of the present application includes a battery cell <NUM>, a fire-fighting pipeline <NUM>, a first fixing member <NUM>, and a second fixing member <NUM>. Specifically, a first wall <NUM> of the battery cell <NUM> is provided with a pressure relief mechanism <NUM>, and the pressure relief mechanism <NUM> is configured to be actuated when an internal pressure or temperature of the battery cell <NUM> reaches a threshold, to relieve the internal pressure. The fire-fighting pipeline <NUM> is configured to accommodate a fire-fighting medium and the fire-fighting pipeline <NUM> is configured to discharge the fire-fighting medium when the pressure relief mechanism <NUM> is actuated. The first fixing member <NUM> is fixed on a side of the fire-fighting pipeline <NUM> close to the first wall <NUM>, the first fixing member <NUM> is provided with a first limiting part <NUM> and a second limiting part <NUM>. The second fixing member <NUM> is fixed on a side of the fire-fighting pipeline <NUM> away from the first wall <NUM>, the second fixing member <NUM> is provided with a third limiting part <NUM> and a fourth limiting part <NUM>, the third limiting part <NUM> and the first limiting part <NUM> are matched with each other to fix the fire-fighting pipeline <NUM> between the first fixing member the member <NUM> and the second fixing member <NUM>, the fourth limiting part <NUM> and the second limiting part <NUM> are matched with each other to limit the second fixing member <NUM> in a first direction, and the first direction is parallel to an extending direction of the fire-fighting pipeline <NUM>, for example, the X direction as shown in <FIG>.

The battery cell <NUM> in the embodiment of the present application may be a hollow polyhedron structure, and the first wall <NUM> may be any wall of the battery cell <NUM>. For example, as shown in <FIG> and <FIG>, in the present application, that the first wall <NUM> is a wall with the smallest area of the battery cell <NUM> is used as an example, but the embodiment of the present application is not limited thereto.

In an embodiment of the present application, a pressure relief mechanism <NUM> is provided on the first wall <NUM>, and the pressure relief mechanism <NUM> can be actuated when an internal pressure or temperature of the battery cell <NUM> reaches a threshold, to relieve the internal pressure and lower the internal temperature. Therefore, the first wall <NUM> is generally not provided on a wall where two battery cells <NUM> are attached to each other. For example, as shown in <FIG> and <FIG>, two adjacent battery cells <NUM> may be attached to each other through a wall with the largest area, and therefore the first wall <NUM> provided with the pressure relief mechanism <NUM> is not the wall with the largest area. On the contrary, if the two adj acent battery cells <NUM> are attached through other walls, the first wall <NUM> provided with the pressure relief mechanism <NUM> may be set as the wall with the largest area.

It should be understood that the pressure relief mechanism <NUM> in the embodiment of the present application is configured to be actuated when the internal temperature or pressure of the battery cell <NUM> reaches a threshold, and the threshold may be set as different values according to different requirements of practical applications. For example, the threshold may depend on the material of one or more of the positive electrode sheet, the negative electrode sheet, the electrolyte and the separator in the battery cell <NUM>. In addition, the pressure relief mechanism <NUM> may take the form of an anti-explosion valve, an air valve, a pressure relief valve, or a safety valve, etc., and may specifically adopt a pressure-sensitive or temperature-sensitive element or structure. That is, when the internal pressure or temperature of the battery cell <NUM> reaches a predetermined threshold, the pressure relief mechanism <NUM> performs an action or a weakened structure provided in the pressure relief mechanism <NUM> is damaged, so as to form an opening or channel for relieving the internal pressure or temperature.

The "actuation" mentioned in the present application means that the pressure relief mechanism <NUM> acts or is activated to a certain state, such that the internal pressure and temperature of the battery cell <NUM> can be relieved. The action generated by the pressure relief mechanism <NUM> may include but is not limited to: at least a portion of the pressure relief mechanism <NUM> being fractured, broken, torn, or opened, etc. When the pressure relief mechanism <NUM> is actuated, high-temperature and high-pressure substances inside the battery cell <NUM> are discharged outwards from an actuated position as emissions. In this way, the pressure of the battery cell <NUM> can be relieved under controllable pressure or temperature, thereby avoiding potentially more serious accidents.

The emissions from the battery cell <NUM> mentioned in the present application include but are not limited to: an electrolyte, dissolved or split positive and negative electrode sheets, fragments of a separator, high-temperature and high-pressure gas generated by reaction, flame, etc..

The fire-fighting pipeline <NUM> in an embodiment of the present application is configured to accommodate a fire-fighting medium, the fire-fighting medium here may be a fluid, and the fluid may be a liquid or gas. The fire-fighting pipeline <NUM> can discharge the fire-fighting medium when the pressure relief mechanism <NUM> is actuated. For example, the fire-fighting pipeline <NUM> may be disposed corresponding to the pressure relief mechanism <NUM>, so that when the pressure relief mechanism <NUM> is actuated, the fire-fighting pipeline <NUM> can be damaged and the fire-fighting medium inside it flows out, which can lower the temperature of the emissions discharged from the pressure relief mechanism <NUM>, to avoid thermal diffusion of the battery cell <NUM> in which thermal runaway occurs and improve the safety of the battery <NUM>.

In addition, in the case where the pressure relief mechanism <NUM> does not damage the fire-fighting pipeline <NUM>, the fire-fighting pipeline <NUM> may not accommodate any substance, but in the case where the pressure relief mechanism <NUM> is actuated, the fire-fighting medium <NUM> may be accommodated in the fire-fighting pipeline, for example, the fire-fighting medium may be controlled to enter the fire-fighting pipeline <NUM> by switching on and off a valve. Alternatively, in the case where the pressure relief mechanism <NUM> is not damaged, the fire-fighting medium <NUM> may always be accommodated in the fire-fighting pipeline, and the fire-fighting medium may also be configured to adjust the temperature of the battery cell <NUM>. Temperature adjustment means heating or cooling a plurality of battery cells <NUM>. In the case of cooling or lowering the temperature of the battery cells <NUM>, the fire-fighting pipeline <NUM> is configured to accommodate a cooling fluid to lower the temperature of the plurality of battery cells <NUM>. In this case, the fire-fighting pipeline <NUM> may also be called a cooling component, a cooling system or a cooling pipeline, etc. The fire-fighting medium accommodated by the fire-fighting pipeline may also be called a cooling medium or a cooling fluid, and more specifically, may be called a cooling liquid or a cooling gas. Optionally, the fire-fighting medium may flow in a circulating manner to achieve better temperature adjustment effects. Optionally, the fire-fighting medium may be water, a mixture of water and ethylene glycol, or air, etc..

It should be understood that the battery cells <NUM>, the fire-fighting pipeline <NUM>, the first fixing member <NUM>, and the second fixing member <NUM> shown in <FIG> and <FIG> may be disposed in the battery <NUM>, for example, disposed in the box <NUM> of the battery <NUM>. Moreover, the box <NUM> of the battery <NUM> in the embodiment of the present application may also be configured to accommodate other components. For example, the box <NUM> may also be provided with a structure configured to fix the battery cells <NUM>. For another example, the box <NUM> may also configured to accommodate a bus component. The bus component may be configured to implement an electrical connection between the plurality of battery cells <NUM>, such as parallel connection, series connection or series-parallel connection. The bus component may implement an electrical connection between the battery cells by connecting electrode terminals <NUM> of the battery cells <NUM>. In some embodiments, the bus component may be fixed to the electrode terminal <NUM> of the battery cell <NUM> by means of welding.

It should be understood that each battery cell <NUM> in the embodiment of the present application may include two electrode terminals <NUM>, and the two electrode terminals <NUM> may be disposed on any one or more walls of the battery cell <NUM>. For example, two electrode terminals <NUM> may be disposed on the same wall, or on two walls respectively. For any electrode terminal <NUM>, it can be disposed on the same wall or different walls as the pressure relief mechanism <NUM>. As shown in <FIG> and <FIG>, in the embodiment of the present application, that two electrode terminals <NUM> are disposed on the first wall <NUM> is taken as an example for illustration.

Specifically, the first wall <NUM> is generally in a shape of a flat plate, two electrode terminals <NUM> of the same battery cell <NUM> are fixed on a flat surface, and the two electrode terminals <NUM> are a positive electrode terminal and a negative electrode terminal, respectively. Each electrode terminal <NUM> is correspondingly provided with a connecting member also called a current collector, which is located between the first wall <NUM> and the electrode assembly inside the battery cell <NUM> and configured to electrically connect the electrode assembly to the electrode terminal <NUM>. For example, one or more electrode assemblies may be disposed at an interior of the battery cell <NUM>, and each electrode assembly has two electrode tabs with opposite polarities. For example, when a first electrode tab of the two electrode tabs is a positive electrode tab, a second electrode tab of the two electrode tabs is a negative electrode tab. The first electrode tab of one or more electrode assemblies is connected to an electrode terminal <NUM> through a connecting member, for example, connected to a positive electrode terminal; and the second electrode tab of one or more electrode assemblies is connected to another electrode terminal through another connecting member, for example, connected to the negative electrode terminal.

The first fixing member <NUM> of the embodiment of the present application is provided with a first limiting part <NUM> and a second limiting part <NUM>, and the second fixing member <NUM> is provided with a third limiting part <NUM> and a fourth limiting part <NUM>. The first limiting part <NUM> and the third limiting part <NUM> can be matched with each other, for example, the first limiting part131 and the third limiting part <NUM> can be fastened to each other by setting a groove structure and a buckle structure, so that the first fixing member <NUM> and the second fixing member <NUM> are relatively fixed in a direction perpendicular to the first wall <NUM>. Further, the fire-fighting pipeline <NUM> may also be fixed between the first fixing member <NUM> and the second fixing member <NUM>, so as to constrain and limit the movement of the fire-fighting pipeline <NUM> in the direction perpendicular to the first wall <NUM>, thereby fixing the fire-fighting pipeline <NUM>. The second limiting part <NUM> and the fourth limiting part <NUM> can be matched with each other, for example, the second limiting part <NUM> and the fourth limiting part <NUM> can be inserted into each other by setting a stopper structure and an opening structure to limit the sliding of the second fixing member <NUM> in the first direction X, so that the second fixing member <NUM> and the first fixing member <NUM> are relatively fixed in the first direction X, thereby effectively fixing the fire-fighting pipeline <NUM>, which can avoid the fire-fighting pipeline <NUM> deviating from or away from the corresponding position of the pressure relief mechanism <NUM>. Further, when the pressure relief mechanism <NUM> is actuated, the fire-fighting pipeline can be damaged smoothly and accurately <NUM> to lower the temperature of the emissions discharged through the pressure relief mechanism <NUM> in time, thereby improving the safety performance of the battery <NUM>.

The first limiting part <NUM>, the second limiting part <NUM>, the third limiting part <NUM>, and the fourth limiting part <NUM> of the embodiment of the present application will be described in detail below with reference to the accompanying drawings. The following is taken as an example for description: the first limiting part <NUM> is a groove structure, the second limiting part <NUM> is a stopper structure, the third limiting part <NUM> is a buckle structure, and the fourth limiting part <NUM> is an opening structure.

Specifically, as shown in <FIG>, the third limiting part <NUM> is a buckle <NUM> extending in the first direction X; the fourth limiting part <NUM> is an opening <NUM> disposed in the buckle <NUM>; the first limiting part <NUM> is a groove <NUM> matched with the buckle <NUM>; the second limiting part is a stopper <NUM> matched with the opening <NUM>, and when the buckle <NUM> is buckled into the groove <NUM>, the stopper <NUM> is located within the opening <NUM> to limit movement of the buckle <NUM> in the first direction X. Such structure arrangement is convenient for processing and assembling.

In an embodiment of the present application, a length of the stopper <NUM> in a second direction is greater than a thickness of the buckle <NUM> in the second direction, and the second direction, for example, the direction Y as shown in <FIG>, is parallel to the first wall <NUM> and perpendicular to the first direction X. This can avoid a case where the buckle <NUM> shuns the stopper <NUM> and slides in the first direction X due to the smaller length of the stopper <NUM> in the second direction Y when the buckle <NUM> is buckled into the groove <NUM>.

In an embodiment of the present application, the stopper <NUM> has a first plane perpendicular to the first direction, and a side wall of the opening <NUM> is matched with the first plane such that the stopper <NUM> is located within the opening <NUM>. The first plane of the stopper <NUM> is matched with the side wall of the opening such that the stopper <NUM> is located within the opening <NUM>, to limit the movement of the buckle <NUM> in the first direction X, which is convenient for processing and assembly.

Specifically, as shown in <FIG>, the stopper <NUM> is a cuboid stopper, and the opening <NUM> is a rectangular opening matched with the cuboid stopper. It should be understood that the stopper <NUM> may also be set as other shapes that have a first plane perpendicular to the first direction. Correspondingly, the opening <NUM> can be set as other shapes matched with the stopper <NUM>, which is not limited in the present application. The stopper <NUM> is set as a cuboid stopper, and the opening <NUM> is set as a rectangular opening, which have simple structures and are convenient for processing and assembly.

In an embodiment of the present application, as shown in <FIG>, in a first direction X, a stopper <NUM> is disposed at one end of a groove <NUM>. In addition, as shown in <FIG>, a groove <NUM> is set to be two segments in the first direction, and the stopper <NUM> is disposed in the middle of the two segments of the groove <NUM>. Whether the stopper <NUM> is disposed at one end of the groove <NUM>, or the stopper <NUM> is disposed in the middle of the two segments of the groove <NUM>, when the buckle <NUM> is buckled into the groove <NUM>, the stopper <NUM> is located within the opening of the buckle <NUM>, all of which can limit the sliding of the buckle <NUM> in the first direction X.

As shown in <FIG>, the third limiting part <NUM> includes a first buckle <NUM> and a second buckle <NUM>, and the first buckle <NUM> and the second buckle <NUM> are separately disposed in the second direction Y. The first limiting part includes a first groove <NUM> and a second groove <NUM>, the first groove <NUM> and the second groove <NUM> are separately disposed in the second direction Y. The first groove <NUM> is matched with the first buckle <NUM>, the second groove <NUM> is matched with the second buckle <NUM>, so that the fire-fighting pipeline <NUM> may be fixed between the first limiting part <NUM> and the third limiting part <NUM> to avoid the fire-fighting pipeline <NUM> deviating from the pressure relief mechanism <NUM> in a direction perpendicular to the first wall <NUM> during the use of the battery <NUM>, thereby ensuring the relative position of the pressure relief mechanism <NUM> and the fire-fighting pipeline <NUM> and ensuring that the fire-fighting pipeline <NUM> can be damaged accurately and timely when the pressure relief mechanism <NUM> is actuated, so as to achieve the effect of cooling.

In an embodiment of the present application, a stopper <NUM> corresponding to the first groove <NUM> and a stopper <NUM> corresponding to the second groove <NUM> are axially symmetrically distributed with the first direction as the axis, for example, the distribution manner as shown in <FIG>.

"A stopper <NUM> corresponding to the first groove <NUM>" mentioned in the present application refers to stoppers <NUM> located on the same side of the first groove <NUM> and arranged in a row with the first groove <NUM> in the first direction X, that is, the stoppers <NUM> disposed at one end of the first groove <NUM> or the stoppers <NUM> disposed in the middle of two segments of the first groove <NUM>. "A stopper <NUM> corresponding to the second groove <NUM>" refers to stoppers <NUM> located on the same side of the second groove <NUM>, and arranged in a row with the second groove <NUM> in the first direction X, that is, the stoppers <NUM> disposed at one end of the second groove <NUM> or the stoppers <NUM> disposed in the middle of two segments of the second groove <NUM>.

In this way, when the first buckle <NUM> is buckled into the first groove <NUM> and the second buckle <NUM> is buckled into the second groove <NUM>, openings of the first buckle <NUM> and the second buckle <NUM> have matched stoppers to limit the sliding of the first buckle <NUM> in the first groove <NUM> and the sliding of the second buckle <NUM> in the second groove <NUM>, and more effectively limit the sliding of the second fixing member <NUM> in the first direction X.

In an embodiment of the present application, a stopper <NUM> corresponding to the first groove <NUM> and a stopper <NUM> corresponding to the second groove <NUM> are symmetrically distributed about the center, for example, the distribution manner as shown in <FIG>. In this way, when the first limiting part <NUM> and the third limiting part <NUM> are installed and matched, if the installation direction is opposite to the original matching direction, the first limiting part <NUM> cannot be matched and installed with the third limiting part <NUM>, which can achieve a structurally fool-proof effect.

In an embodiment of the present application, a number of the stoppers <NUM> corresponding to the first groove <NUM> differs from a number of the stoppers <NUM> corresponding to the second groove <NUM>. For example, one end of the first groove <NUM> may be provided with one stopper <NUM> correspondingly, and one end of the second groove <NUM> may not be provided with a stopper <NUM>; alternatively, both ends of the first groove <NUM> each may be provided with one stopper <NUM>, and one end of the second groove <NUM> may be provided with one stopper <NUM> correspondingly; as shown in <FIG>, both ends of the first groove <NUM> each may be provided with one stopper <NUM>, and one end of the second groove <NUM> is correspondingly provided with one stopper <NUM>.

In this way, when the first limiting part <NUM> and the third limiting part <NUM> are installed and matched, if the installation direction is opposite to the original matching direction, the first limiting part <NUM> cannot be matched and installed with the third limiting part <NUM>, which can achieve a structurally fool-proof effect.

In an embodiment of the present application, the first fixing member <NUM> is provided with an accommodating part <NUM> configured to accommodate an electrode terminal <NUM>. Specifically, the first fixing member <NUM> is disposed on a surface of the first wall <NUM> away from an interior of the battery cell <NUM>, and when the first wall <NUM> is provided with the electrode terminals <NUM>, the accommodating part <NUM> may be provided to shun the electrode terminal <NUM>. As shown in <FIG>, the accommodating part <NUM> may include a through hole <NUM>, so that the electrode terminal <NUM> can pass through the through hole <NUM>, and the accommodating part <NUM> surrounds the electrode terminal <NUM>. In this way, a surface of one end of the electrode terminal <NUM> away from the battery cell <NUM> is exposed, and the bus component may be connected to the electrode terminals <NUM> of the plurality of battery cells <NUM> by means of welding or the like, thereby achieving the electrical connection of the plurality of battery cells <NUM>, and the first fixing member <NUM> may also be relatively fixed to the battery cell <NUM> through the accommodating part <NUM>.

Optionally, as shown in <FIG>, each electrode terminal <NUM> is generally cylindrical, and correspondingly, the through hole <NUM> of the accommodating part <NUM> may also be set as a circular through hole to accommodate the electrode terminal <NUM>.

In an embodiment of the present application, the box <NUM> may also be provided with a beam <NUM> configured to fix the battery cells <NUM>, and the beam <NUM> is configured to attach to at least one battery cell <NUM> among the plurality of battery cells <NUM> to fix the plurality of battery cells <NUM>.

The embodiment of the present application does not make any limitation on the arrangement manner of the beam <NUM> in the box <NUM>. In one example, one side of the beam <NUM> is attached to a side wall of the box <NUM>, and the other side of the beam <NUM> is attached to the battery cell <NUM>, and in this case, the beam <NUM> may also be regarded as part of the side wall of the box <NUM>. In another example, both sides of the beam <NUM> are respectively attached to the battery cells <NUM>, and in this case, the beam <NUM> may be regarded as an auxiliary structural member for improving installation stability of the plurality of battery cells <NUM> in the box <NUM>, where the beam <NUM> may also be called a cross beam.

In the box <NUM>, according to actual usage requirements, the number of beams <NUM> may be flexibly set, for example, <NUM>, <NUM>, <NUM>, or other numbers. When the number of beams <NUM> is multiple, the plurality of beams <NUM> may be all the side walls of the box <NUM>, may be all cross beams, or may be partly the side walls of the box <NUM> and partly be the cross beams, and the present application is not limited to this.

Optionally, as shown in <FIG>, two sides of a beam <NUM> are respectively attached to a battery cell <NUM>, and a hole <NUM> is provided on the beam <NUM>. Correspondingly, as shown in <FIG>, the first fixing member <NUM> is provided with a fixing part <NUM>, and the fixing part <NUM> is matched with the hole <NUM> to fix the first fixing member <NUM> on a surface of the beam <NUM> close to the fire-fighting pipeline <NUM>. The shape of the fixing part <NUM> may be any shape matching the hole <NUM>, which is not limited in the present application. <FIG> is the front view of <FIG>, and as shown in <FIG>, the fixing part <NUM> is shaped like a fir tree. During installation, the fixing part <NUM> may be screwed into the hole <NUM> by rotating the first fixing member <NUM> for many times, so that the first fixing member <NUM> is stably fixed on the surface of the beam <NUM> close to the fire-fighting pipeline <NUM>.

It should be understood that the battery <NUM> in an embodiment of the present application may include a plurality of battery cells <NUM> disposed in the first direction X. The first wall <NUM> of each battery cell <NUM> is provided with a pressure relief mechanism <NUM>, and the fire-fighting pipeline <NUM> is provided corresponding to the pressure relief mechanism <NUM>. Therefore, the fire-fighting pipeline <NUM> may be arranged as a long strip pipeline in the first direction X. Correspondingly, in order to realize the fixing of the fire-fighting pipeline <NUM>, the battery <NUM> may include one or more first fixing members <NUM>, and the battery <NUM> may also include one or more second fixing members <NUM>.

In the embodiment of the present application, the battery <NUM> includes a plurality of battery cells <NUM> arranged in the first direction X and a plurality of first fixing members <NUM> and at least one second fixing member <NUM> arranged in the first direction X. As shown in <FIG>, when the battery <NUM> includes a plurality of battery cells <NUM> arranged in the first direction X, the fire-fighting pipeline <NUM> is usually in a long strip. Therefore, the plurality of first fixing members <NUM> are provided to fix the fire-fighting pipeline <NUM>, which can make the fire-fighting pipeline <NUM> more stable.

In an embodiment of the present application, one second fixing member <NUM> corresponds to a plurality of first fixing members <NUM>, that is, one second fixing member <NUM> may be matched with a plurality of first fixing members <NUM>, to fix the fire-fighting pipeline <NUM> between the first fixing member <NUM> and the second fixing member <NUM>. As shown in <FIG>, the second fixing member <NUM> extends in the first direction X to reduce the number of the second fixing members <NUM>, thereby improving the processing and assembly efficiency of the second fixing member <NUM>.

It should be understood that the number of first fixing members <NUM> corresponding to each second fixing member <NUM> may be flexibly set according to practical applications. For example, the number of first fixing members <NUM> is usually set to be smaller than the number of battery cells <NUM>, and the embodiment of the present application is not limited to this.

According to an embodiment of the present application, a power consumption device is also provided, including the battery <NUM> in the foregoing embodiment. Optionally, the power consumption device may be a vehicle <NUM>, a ship or a spacecraft, etc., but this is not limited by the embodiment of the present application.
