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.

Abstract: Presented is battery packaging material which is made of a laminate including, as the essentials, a base material layer, a metal layer and a sealant layer in this order. When a product obtained by packaging a battery element with the packaging material in a hermetically sealed state through heat sealing is heated, the packaging material delaminates at least at a part of the interface between the metal layer and the outside surface of the sealant layer with the hermetically sealed state being kept, and thereafter works so as to make the product unsealed.

Abstract: A battery packaging material of a first aspect identifiable from the outside has exceptional moldability, insulating properties, and reduced external appearance defects and seal defects. A battery packaging material of the second aspect identifiable has post-molding concealment and adhesion properties, exceptional electrolyte resistance and surface insulating properties. The battery packaging material of the first aspect includes a laminate of at least a base material, adhesive, metal and sealant layers sequentially laminated, at least one of the base material and adhesive layers includes a dye. The battery packaging material of the second aspect includes a laminate of at least a decorative, base material, metal and sealant layers sequentially laminated; the decorative layer has at least a first and second decorative layers from the base material layer side. The decorative layer includes coloring and matting agents. The resin ratio is at least 60% by mass for the first and second decorative layers.
