Abstract: A power storage device packaging material having a structure including at least a substrate layer, an adhesive layer, a metal foil layer, a sealant adhesive layer, and a sealant layer laminated in this order. The substrate layer is formed of a polyester film exhibiting ?A, as expressed by the following formula, of 10% or more and a 50% elongation stress of 75 MPa or more after heat treatment at 160° C.: “?A=(break elongation after 160° C. heat treatment)?(break elongation before 160° C. heat treatment)”.

Abstract: The present invention relates to a packaging material for a power storage device, the packaging material including at least a slip agent layer, a substrate layer, an adhesive layer, a metal foil layer, a sealant adhesive layer, and a sealant layer, in this order, wherein the slip agent layer contains a fatty acid amide and a fatty acid bisamide, or a fatty acid amide and silicone oil.

Abstract: A power storage device packaging material including a base material layer; an adhesion-enhancing treatment layer on a surface of the base material layer; an adhesive layer on a surface of the adhesion-enhancing treatment layer opposite the base material layer; a metal foil layer formed on one side of the adhesive layer opposite the adhesion-enhancing treatment layer; and a sealant layer disposed on a surface of the metal foil layer opposite the adhesive layer. The base material layer is formed of a biaxially oriented film to have a breaking strength of 240 MPa or more in at least one of four directions (0° (MD), 45°, 90° (TD), 135°) and an elongation of 80% or more in at least one direction in a tensile test (test specimen shape: test specimen type 5 stipulated in JIS K7127; inter-chuck distance: 60 mm; tensile speed: 50 mm/min).

Abstract: An outer packaging material for electric storage device comprises at least a substrate layer, an adhesion layer, a metal foil layer, a sealant adhesion layer, and a sealant layer laminated in this order, wherein the substrate layer is one made of either a polyamide film having a hot water shrinkage rate at 95° C. of less than 5% and a hot shrinkage rate at 180° C. of 4 to 16%, or a polyester film having a hot water shrinkage rate at 95° C. of less than 5% and a hot shrinkage rate at 180° C. of 10 to 25%.
