Abstract
A pouch cell includes a generally rectangular cell housing formed of a metal laminated film that includes a box portion and a lid portion that is formed separately from the box portion. The active material including the electrode and an electrolyte is placed into the box portion and the lid portion is welded to the box portion. The box portion and the lid portion are formed and assembled together without using a drawing or a punching process. Instead, the pouch cell housing is formed via a series of folding and welding steps, whereby the pouch cell size is not limited by the draw depth of the metal laminated film.
