Abstract
A flat alkaline cell is described wherein an electrode assembly including at least a pair of flat electrode elements of opposite polarity having a porous separator containing an alkaline electrolyte interposed therebetween and a current collector disposed adjacent to and in electrical connection with one of the pair of electrode elements at one end of the electrode assembly, are enclosed within a sealed, liquid impervious plastic film envelope having an opening in one wall thereof which exposes at least a portion of the current collector for making external electrical connection therewith, and wherein a layer of an adhesive sealant which is non-wettable by the alkaline electrolyte, tightly adheres and seals together the current collector and the wall of the envelope at least around the periphery of the opening. The exposed portion of the current collector constitutes a first terminal connection to which a wire lead or the like may be attached. A second and third terminal connection are provided in the sealed envelope, the former being in electrical connection with the other of the pair of electrode elements of opposite polarity and the latter being in electrical connection with an auxiliary electrode.
