Abstract: A method for preparing cathode material for a lithium primary battery includes an active cathode material and an active anode material. The active cathode material is manganese dioxide, and the active anode material is either one of lithium metal and lithium alloy. The method includes: a first kneading step in which a boron compound and a thickening agent are kneaded with a diluent to prepare a paste made by dissolving the boron compound in the diluent; a second kneading step in which the paste is kneaded with a conductive additive; and a third kneading step in which the paste obtained in the second kneading step is kneaded with the active cathode material and a binder to prepare the cathode material in slurry form.

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.

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.
