Abstract: A packaging material 1 for a power storage device is configured to include a polyamide resin layer 2 as an outer layer, a polyolefin resin layer 3 as an inner layer, and an aluminum foil layer 4 arranged between both the layers. A thickness of the packaging material 1 for a power storage device is 90 μm or less, a tensile breaking strength of the packaging material for a power storage device is 110 N/15 mm width or more, and a tensile breaking elongation of the packaging material for a power storage device is 90% or more. This enables to provide a packaging material for a power storage device thin in thickness and light in weight which is capable of securing excellent formability even when deep shape forming is performed and also is high in mechanical strength and excellent in impact resistance.

Abstract: A packaging material 1 includes a heat resistant resin stretched film layer 2 as an outer layer, a thermoplastic resin layer 3 as an inner layer, a metal foil layer 4 arranged between these layers, and a colored ink layer 10 arranged between the metal foil layer 4 and the heat resistant resin stretched film layer 2. As the heat resistant resin stretched film, a heat resistant resin stretched film having a hot water shrinkage rate of 2% to 20% is used, and the heat resistant resin stretched film layer 2 and the colored ink layer 4 are integrally laminated via an easily adhesive layer 30. In this packaging material, at the time of forming and sealing, and even being used in a somewhat severe environment such as high-temperature and humid environment, the colored ink layer will not be detached from the heat resistant resin stretched film layer.

Abstract: A packaging material for a power storage device includes a heat resistant resin layer 2 as an outer layer, a sealant layer 3 as an inner layer, and a metal foil layer 4 arranged between these layers. The sealant layer 3 is composed of one layer or a plurality of layers. The innermost layer 7 of the sealant layer contains a random copolymer containing propylene as a copolymerization component and another copolymerization component other than propylene, a roughening material, and a lubricant. The roughening material is composed of particles containing a thermoplastic resin. The center line average roughness Ra of the surface 7a of the innermost layer 7 is 0.05 μm to 1 μm. It can provide a packaging material for a power storage device which is excellent in formability and hard to generate white powder on the surface.

Abstract: A sealant film has a structure made of a laminated body of two or more layers. The laminated body includes a first resin layer 7 containing 50 mass % or more of a random copolymer containing propylene and a copolymer component other than propylene as copolymer components, and a second resin layer 8 formed by a mixed resin containing a first elastomer-modified olefin based resin having a melting point of 155° C. or higher and a crystal melting energy of 50 J/g or more, and a second elastomer-modified olefin based resin having a melting point is 135° C. or higher and a crystal melting energy of 30 J/g or less. With this structure, when the inner pressure of a power storage device is excessively increased, breakage (separation) occurs inside the sealant layer, causing gas-releasing, which in turn can prevent bursting of the packaging material due to the inner pressure increase.

Abstract: In an external member, peripheral edge regions of first and second metal foil layers are joined via a periphery sealing portion containing thermoplastic resin. A plurality of bare cells are arranged separately in internal spaces surrounded by the first metal foil layer, the second metal foil layer and the periphery sealing portion. The partition region of the first metal foil layer between adjacent bare cells and the partition region of the second metal foil layer between adjacent bare cells are joined via the partition sealing portion. Thus, the internal space is partitioned into a plurality of independent individual spaces. At each individual space, the first metal foil inner exposed portion and the positive electrode portion are connected electrically, and the negative electrode portion of the second metal foil inner exposed portion and the bare cell are connected electrically. The bare cell and electrolyte are encapsulated in each individual space.
