Patent ID: 8822068

Claim:
A pouch type secondary battery comprising: an electrode assembly having a first electrode plate, a second electrode plate, and a separator; a pouch case made of a flexible material, the pouch case comprising a cover and a container, which is insulated at least on an inner surface thereof and accommodating the electrode assembly, and sealing portions along an edge of the container, the sealing portions comprising a first sealing portion through which electrode tabs of the electrode assembly extend from the pouch case and a second sealing portion and a third sealing portion positioned at opposite sides of the first sealing portion, the second and third sealing portions being folded at least one time and wherein the pouch case defines side walls of a first height adjacent the second and third sealing portions and an upper surface that interconnects the side walls; a protective circuit module connected to the electrode tabs and mounted on the first surface of the first sealing portion so as to be secured thereto; 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, wherein the second and third sealing portions are folded toward the second surface of the pouch case to be opposite the side walls of the pouch case and the protective circuit module on the first surface of the first sealing portion such that the upper surface of the pouch case that interconnects the sidewalls is exposed, and wherein the short circuit protector comprises folded portions of the respective second and third sealing portions, wherein the pouch case is packaged into an external pack with a first adhesive member interposed between the external pack and at least the second surface of the pouch case, and the first adhesive member is positioned between the folded portions of the respective second and third sealing portions such that the portion of the second surface of the pouch case combined with the adhesive has a thickness that is less than or equal to the thickness of the second and third sealing portions, such that the folded portions of the second and third sealing portions do not increase an overall thickness of the external pack, wherein a second adhesive member adheres with the external pack and the upper surface of the pouch case, and wherein the second and third sealing portions are folded toward the second surface of the pouch case opposite to the protective circuit module mounted on the first surface of the first sealing portion, wherein the second surface of the pouch case is an outer surface of the cover opposite to the first surface of the first sealing portion, and wherein the side walls extend outward from the first surface.
