Abstract:
1. A pouch-type battery including an electrode assembly having a cathode/separator/anode structure which is mounted into a pouch-shaped battery case and sealed by the battery case, wherein the pouch-type battery includes the cathode and the anode protruding from opposite sides of the battery case in opposite directions, the pouch-type battery is constructed in a structure in which two receiving parts are formed at a one-unit sheet-type battery case in a symmetrical fashion such that an electrode assembly is received in the receiving parts, the battery case is bent between the two receiving parts along a single bending line such that one of the receiving parts overlaps with the other receiving part while the electrode assembly is received in the other receiving part, the bent battery case being sealed, the two receiving parts are continuously formed while the two receiving parts are in contact with the single bending line, and the battery case is provided at the edge thereof where the single bending line runs with bent depression parts having a depth equivalent to that of the receiving parts, wherein the two receiving parts communicate with each other about the single bending line, the two receiving parts constitute an integral receiving structure, and the receiving parts are divided about the single bending line running through the middle of the integral receiving structure, and wherein the sealing is accomplished by thermal welding.
