Abstract: A packaging material for a power storage device, including: a metal foil layer; a coating layer formed on a first surface of the metal foil layer directly or via a first anti-corrosion treatment layer; a second anti-corrosion treatment layer formed on a second surface of the metal foil layer; an adhesive layer formed on the second anti-corrosion treatment layer; and a sealant layer formed on the adhesive layer. The coating layer contains at least one material selected from a group consisting of fluorine-based resins, urethane-based resins, and polyester-based resins. There is also a strength difference between the coating layer and a laminate of the adhesive layer and the sealant layer at a 10 percent stretch conducted in a tensile test (in conformity with JIS K 7127) of less than 0.400 N/mm.

Abstract: A packaging material for a power storage device, comprising: a coating layer disposed directly on a first surface of a metal foil or disposed via a first corrosion protection layer; and a second corrosion protection layer, a sealant adhesive layer, and a sealant layer disposed in this sequence on a second surface of the metal foil, wherein the coating layer is produced from an aromatic polyimide resin made of a tetracarboxylic dianhydride or derivatives thereof and a diamine or derivatives thereof, and wherein the coating layer has a tensile elongation in a tensile test (in compliance with JIS K7127, JIS K7127 specimen type 5, tensile rate 50 mm/min) is not less than 20% in an MD direction and a TD direction.
