ABSTRACT:
An electrochemical cell is provided with first (10) and second (11) electrodes and a solid polymer electrolyte (15) disposed therebetween. The electrodes include a current collecting layer, a layer of electrode active material, and a layer of an electrically conductive, polymeric protection material disposed therebetween. The protective layer protects, for example, the current collecting layer from the deleterious effects of the acid or alkaline electrolyte active species found in most electrochemical cells. The protective layer is formed of an intermetallic compound dispersed through a layer of appropriately chosen polymeric material.
