PURPOSE: A large-area battery is provided to prevent the swelling inside the cell by binding an inner wall facing an exterior like a pouch through a physical method. CONSTITUTION: A large-area battery(100) for preventing the swelling includes a folded cell(110), an aluminum pouch(120) finishing the cells by unit, and a thermally adhesive member(130) which interconnects an inner wall facing an aluminum pouch by thermal adhesion. The thermally adhesive member connects both inner walls facing the aluminum pouch through a hole(112) formed on the cell, or connects both outer walls facing the cell and both inner walls facing the aluminum pouch. |
