<p>PROBLEM TO BE SOLVED: To provide a laminate sheath material for a battery which makes possible to lighten the weight by reducing the entire thickness of a sheath material, to perform an adhesion to a battery main body with reliability at the time of thermal adhesion, and to perform a firm adhesion to even a plastic part for end portion reinforcement.SOLUTION: A laminate sheath material for a battery comprises: an aluminum foil 3; a first coating film layer 1 made of a base resin and laminated on one surface of the aluminum foil by coating the surface of the aluminum foil with the base resin; and a second coating film layer 2 formed on a surface of the first coating film layer 1. The second coating film layer is made of a heat-adhesive resin which can be caused to adhere to a surface film of a battery main body and has a softening point of 160°C or lower.</p> |
