ABSTRACT:
In making an electrode for a lead-acid accumulator or the like, a supporting body of titanium is immersed in a boiling solution of oxalic acid containing the ions of a titanium-oxalato complex. This treatment is followed by anodic coating of the titanium body with PbO.sub.2 in an electrolyte containing the ions of lead (II), in the presence of a lead (II) salt of an amido, imido, nitrido or fluoro sulfate or phosphate at least during a first anodizing stage. The coated electrode may be further immersed in a weakly medium for a prolonged period.
