Abstract: A laminate-type power storage element has a flat body and an interior layered flat plate-shaped electrode body. A positive electrode terminal plate is mounted to a positive electrode of the electrode body and is guided outside from a predetermined margin of the body. A negative electrode terminal plate is mounted to a negative electrode of the electrode body and guided in the same direction. A film member spans across both electrode terminal plates. The film member is made by layering an insulating heat-resistant film and an adhesive to thermocompression bond the heat-resistant film to a matter to be adhered to. The film member is thermocompression bonded to the electrode terminal plate at a region facing principal surfaces of the positive and the negative plates, and is thermocompression bondable to the matter to be adhered to in a region that does not face the respective principal surfaces.

Abstract: A laminate-type power storage element includes a flat plate-shaped electrode body and an exterior body. The electrode body is configured by stacking a sheet-shaped positive electrode and a sheet-shaped negative electrode on either side of a separator. The exterior body is formed in a flattened bag-shape by thermocompression bonding peripheral edge regions of two opposing laminated films, to seal the electrode body inside the flattened bag-shape of the exterior body together with an electrolyte. The separator has a sheet-shaped substrate and at least one bonding layer formed on at least one surface of the substrate. A peripheral edge portion of the separator is sandwiched between and bonded by the two laminated films at a peripheral inside of the peripheral edge regions of the two laminated films.

Abstract: At least one of positive and negative electrode plates constitutes a flat plate-shaped electrode body in a laminated power storage element. The laminated power storage element includes a casing formed into a flat bag and the electrode body sealed in the casing together with an electrolyte. The at least one of the electrode plates includes: a sheet-shaped metal current collector; and an electrode material. The electrode material includes a powder material including an electrode active material and a binder including an emulsion, the binder added to the powder material. The electrode material is applied, at a predetermined thickness, onto the current collector. The at least one of the electrode plates is formed into a predetermined planar shape by shearing off a peripheral area thereof through a shearing process.
