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.
