PACKAGING MATERIAL FOR CELL

WIPO Patent Application WO/2013/183511

A1

The objective of the present invention is to provide a technique for imparting exceptional moldability and reducing the incidence of cracking and pinholing during molding in a packaging material for a cell comprising a layered film in which at least a base-material layer, an adhesive layer, a metallic layer, and a sealant layer are layered in the stated order. The packaging material for a cell comprising a layered body in which at least a base-material layer, an adhesive layer, a metallic layer, and a sealant layer are layered in the stated order, wherein the packaging material for a cell can be imparted with highly exceptional moldability, and dramatically less prone to pinholing and cracking during molding by using, as the metallic layer, an aluminum foil having 0.2% proof strength of 58-121 N/mm2 when a tensile test is performed in the direction parallel to the rolling direction.
