Abstract:
A thin type cell comprising an outer sheath defining an interior of the cell for accommodating a cathode, an anode and an electrolyte, the outer sheath comprising a moisture-proofing three-layered film consisting of a heat fusible layer and a second layer with a metal foil layer sandwiched therebetween, the heat fusible layer facing the interior of the cell, and electrode terminals interconnecting electrodes and external terminals are formed of a netted or porous electrically conductive member, the electrode terminals passing through the outer sheath with the heat fusible layer sealingly engaging the terminals, the heat fusible layer containing a resin material that engages the terminals at a sealing portion along at least a portion of the terminals wherein a thickness of the resin material is two to three times thicker than an electrode terminal thickness of each electrode terminal.
