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 ΔA, 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.: “ΔA=(break elongation after 160° C. heat treatment)−(break elongation before 160° C. heat treatment)”.

Abstract: A packaging material for a power storage device 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. In the packaging material, the substrate layer is formed of a polyester film having a 50% elongation stress in the range of 100 to 180 MPa and a thermal shrinkage in the range of 1 to 15%, after heat treatment from 160° C. to 200° C., or a polyester film having a difference ΔA in break elongation of 12% or more after heat treatment at 200° C. and 160° C. and having a 50% elongation stress of 75 MPa or more after heat treatment at 200° C.

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).
