Document Type and Number:
WIPO Patent Application WO/2013/099761
Kind Code:
A1
Abstract:
Provided are: a laminate for battery packages, which has excellent electrolyte solution resistance and heat resistance; a battery case which is molded using this laminate; and a battery which uses the battery case.
A laminate for battery packages, wherein an aluminum foil layer and an outer layer that is composed of a heat-resistant resin film are laminated on each other and an inner layer that is composed of a thermoplastic resin film is laminated on the other surface of the aluminum foil layer, said surface being different from the outer layer-side surface. In this laminate for battery packages, an adhesive layer, which contains a reaction product of a compound that has two or more isocyanate groups in each molecule and a reactive functional group-containing styrene elastomer that has at least one reactive functional group selected from the group consisting of a carboxyl group, an amino group and a hydroxyl group, is interposed at least between the aluminum foil layer and the inner layer.
