  • Publication number: 20220231358
    Abstract: In a laminate-type power storage element, laminated films forming an exterior body are each formed by sandwiching a metal layer between a resin layer and a heat sealing layer. An electrode body includes a positive electrode and a negative electrode disposed opposite to each other across a separator and is enclosed together with a non-aqueous organic electrolyte solution inside the exterior body. Particles included in the positive electrode or negative electrode have a D90 particle size less than or equal to the thickness of the heat sealing layer.

  • Patent number: 10923698
    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: A laminated rechargeable element includes a jacket and an electrode assembly. The electrode assembly is accommodated in the jacket together with an electrolyte, and includes a separator, a sheet-shaped positive electrode and a sheet-shaped negative electrode. The electrode assembly is formed by laminating the positive electrode and the negative electrode with the separator interposed between the positive electrode and the negative electrode. The separator includes an ion-permeable substrate and ion-permeable bonding layers formed on a top surface and a bottom surface of the substrate. The positive electrode and the negative electrode are welded to respective bonding layers of the separator. The jacket is formed of two flat, rectangular stainless steel laminate films welding together at their peripheries, and is welded to the electrode assembly.

  • Patent number: 10546700
    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.
