ABSTRACT:
A pouch type secondary battery which can prevent a cut portion from electrically contacting a protective circuit module, thereby preventing an electrical short circuit and acceleration of corrosion of a core material and enhancing safety includes an electrode assembly having a first electrode plate, a second electrode plate, and a separator; a pouch case made of a flexible material, and having a container, insulated at least on its inner surface and accommodating the electrode assembly, and sealing portions along an edge of the container, the sealing portions including a first sealing portion through which electrode taps of the electrode assembly extend from the pouch case, and a second sealing portion and a third sealing portion respectively positioned at opposite sides of the first sealing portion, the second an third sealing portions being folded at least one time; a protective circuit module connected to the electrode taps and mounted on an outer surface of the first sealing portion; and a short circuit protector formed in at least one among the first through third sealing portions to prevent an electrical short circuit between each sealing portion and the protective circuit module.
