PACKAGING MATERIAL FOR CELL |
| 摘要 |
A packaging material for a cell including 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 including 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% yield strength of 58-121 N/mm2 when a tensile test is performed in the direction parallel to the rolling direction. |
