Abstract
The present invention relates to a laminate for battery encasement comprising aluminum foil and an inner layer, wherein a resin film layer that comprises an aminated phenol polymer (A), an acrylic polymer (B), a phosphorus compound (C), and a zirconium compound (D) lies between the aluminum foil and the inner layer. The laminate for battery encasement of the present invention is excellent in adhesiveness, gas impermeability, etc., and therefore can be suitably used as a material for encasing a secondary battery, particularly a lithium ion polymer secondary battery.
