Claim 12:
13. A method for manufacturing a secondary battery, the method comprising:
a step (a) of manufacturing an electrode assembly by stacking and winding a first electrode sheet and a second electrode sheet with a separation sheet interposed therebetween, wherein a first electrode tab protrudes in the first electrode sheet, and a second electrode tab protrudes in the second electrode sheet;
a step (b) of manufacturing a connection part, which comprises a first area that is made of an electrically conductive gel material and a second area that is attached to the first area and made of electrically insulating material, wherein the second area forms at least a portion of a top surface of the connection part;
a step (c) of disposing the connection part both above and below the electrode assembly, inserting at least a portion of the first electrode tab into the first area of the connection part disposed above the electrode assembly, and inserting at least a portion of the second electrode tab into the first area of the connection part disposed below the electrode assembly; and
a step (e) of accommodating the electrode assembly in a battery can and coupling a cap assembly to an opening of the battery can.
