Abstract
Abstract A laminar battery (26) has an anode layer, an ionically conductive electrolyte layer, and a cathode layer. The electrolyte layer is interposed between the anode layer and the cathode layer, and the layers are assembled to form an electrical cell. A pair of electrically conductive terminals are in electrical contact with the anode layer and the cathode layer. A protective sheet material (28) envelops the laminar battery and is heat sealed at the periphery of the laminar battery (26) and about the terminals (32,34) to exclude air and moisture. The terminals (32,34) extend from or are accessible through this protective sheet material (28) for connection to a device which is to be powered by the laminar battery (26).
