Abstract: A packaging material for a power storage device with excellent moldability is provided. The present invention is directed to a packaging material for a power storage device. The packaging material includes a metal foil layer 4, a substrate layer 2 made of a resin and provided on the outer side of the metal foil layer 4, an adhesive layer 5 provided on the inner side of the metal foil layer 4, and a heat-fusible layer 3 made of heat-fusible resin and provided on the inner side of the adhesive layer 5. The heat-fusible layer 3 includes a metal foil side layer portion 33 bonded to the adhesive layer 5 and a seal layer portion 31 located on the innermost surface. Particles with an average particle diameter of 0.05 µm or more but less than 5 µm are defined as "micro particles," and particles with an average particle size of 5 µm or more but less than 20 µm are defined as "coarse particles." The seal layer portion 31 is composed of a layer containing the micro particles and the coarse particles, and the metal foil side layer portion 31 is composed of a constituent layer that contains the micro particles but does not contain particles with an actual particle size of 5 µm or larger.

Abstract: Provided is a secondary battery pouch film in which at least an outer layer, a barrier layer, and a sealant layer are structured in that order, wherein the outer layer includes nylon and polyethylene terephthalate films, the barrier layer is made of aluminum, and the Poisson's ratio is 0.4 to 0.5, a method for preparing the pouch film, a secondary battery using the same, and a method for manufacturing the secondary battery. The cracks at the edge that occur during deep forming of the secondary battery pouch film may be suppressed, and the edge may be formed thick, thereby providing excellent high formability. Since the secondary battery pouch film is capable of improving the energy density of secondary batteries, it is particularly useful as a medium to large-sized secondary battery pouch film for electric vehicles or energy storage devices.
