Abstract
The present disclosure relates to a pouch casing material including two cups forming an electrode assembly receiving portion and formed integrally in one pouch film. The pouch casing material includes an upper pouch member and a lower pouch member formed integrally with each other, and the connection between the upper pouch member and the lower pouch member does not protrude toward the outside. Thus, the total length of a battery is reduced.
