BATTERY-PACKAGING MATERIAL |
摘要 |
To provide a technique for a battery-packaging material made of a film-form laminate in which at least a base material layer, an adhesive layer, a metal layer, and a sealant layer are laminated successively, wherein: electrolytic solution resistance is further improved by including a polyester film in the base material layer; cracks and pinholes are less likely to be created at the time of forming the polyester-film-including base material layer; and formability is improved. This battery-packaging material is made of a laminate in which at least a base material layer, an adhesive layer, a metal layer, and a sealant layer are laminated successively, wherein: the base material layer includes a polyester film; and the metal layer is an aluminum foil in which the 0.2% proof stress at the time of performing a tensile test in a direction parallel to the rolling direction is from 55 to 140 N/mm2. |

1. A battery packaging material comprising a laminate in which at least a base material layer, an adhesive layer, a metal layer and a sealant layer are laminated in this order, wherein
the base material layer includes a polyester film, and the metal layer is an aluminum foil having a 0.2% yield strength of 55 to 140 N/mm2 when a tensile test is conducted in a direction parallel to a rolling direction. |
