Abstract
An electrode suitable for use as a lead-acid battery plate contains an inorganic metal oxide additive which enhances the formation of the plate. The additive is electrically conductive, stable in aqueous solutions of sulfuric acid, but does not participate in the electrode reaction. Suitable metal oxides include barium metaplumbate and other ceramic perovskite materials having similar properties. The conductive ceramic may also be used in electrodes for bipolar lead-acid batteries and in an electrode, particularly an anode (positive electrode), used in electrolytic processes.
