Abstract

The purpose of the present invention is to provide a film-like battery packaging material in which a coating layer, which can be cured in a short time and exhibits superior chemical resistance, is provided to a substrate layer surface. In the battery packaging material, which comprises a laminate body that includes at least a coating layer, a substrate layer, an adhesive layer, a barrier layer, and a sealant layer, in that order, the use of a resin composition containing a heat-curable resin and a curing accelerator as the coating layer enables the formation of a coating layer that can be cured in a short time and contributes to electrolyte liquid, etc., resistance.
