Abstract (en)
[origin: WO9419837A1] A battery electrode (12) for use in an electrolytic bipolar battery (10) comprises a structurally rigid and electrically conductive core member (18), at least one corrosion resistant layer (20), an interface layer (22), a positive-side active layer (14) and a negative-side active layer (26). The corrosion resitant layer (20) is in intimate contact with and is interposed between one surface of the core member (18) and the interface layer (22). The corrosion resistant layer is comprised of a material which can participate in a corrosive electrochemical reaction with the material of the positive active layer, but does so less effectively than does the interface layer. The interface layer (22) is in intimate contact with and is interposed between the corrosion resistant layer (20) and the positive-side active layer (14). The negative-side active material (26) is in intimate contact with the surface of the core member opposite the core member surface carrying the corrosion resistant layer. The margins of the electrode are connected to nonconductive components (30) of the battery which space plural ones of the electrodes from each other. Those connections are made via marginal surface portions (40) of the electrodes from which oxides (36) have been removed. The connections form seals which are secure from leakage of electrolyte through the seals.
