Abstract
A secondary battery is manufactured by mounting an electrode assembly having a cathode/separator/anode structure into a pouch-shaped battery case and thermally welding the electrode assembly to the battery case, wherein a pair of insulative films are attached to opposite major surfaces of each electrode lead, to which electrode taps of the electrode assembly are electrically connected, at regions contacting an upper thermally-welded portion (upper sealed portion) of the pouch-shaped battery case, one of the insulative films, extends such that the lower end of the insulative film supports a coupled region where the electrode taps are coupled to the electrode lead, and the overlapping length between the insulative films is equal to or slightly greater than the height of the upper sealed portion.
