METHOD OF MAKING BATTERY USING AS CASE WITH ALUMINIUM MULTILAYERED FILMS

摘要

A method of manufacturing a battery using a pouch of aluminum multilayered film is disclosed. The pouch of an aluminum multilayered film is used as the outer case of the battery. The method includes: inserting an electrode assembly in the pouch, which is composed of an anode, a separator, and a cathode; sealing the electrode assembly; and bending the sealed portion of the battery once or twice. Therefore, the present invention can enhance the safety and energy density of the battery.
