ABSTRACT:
Electric storage batteries with titanium or other film forming metal anodes and cathodes are provided. The anodes are coated with mixed oxide coatings of a film forming metal oxide containing a platinum group metal oxide catalyst, which coatings may contain oxides of other metals to alter the breakdown voltage and increase the oxygen overpotential of the cathodes while preserving a low bromine and chlorine overpotential. The cathodes may be uncoated titanium or other film forming metals or film forming metals with a silver coating thereon. Bipolar film forming metal cathodes and anodes are provided carrying a mixed oxide coating on the cathodic face and either no coating or a silver coating on the anodic face. The invention is applicable to all types of electric storage batteries, either primary or secondary, and multiple batteries may be connected in series or in parallel to provide the desired amperage and voltage characteristics.
