ABSTRACT:
In making a lead electrode for a lead-acid accumulator or the like, a supporting body of titanium is pickled in a boiling solution of oxalic acid and then adsorptively coated with a titanium (IV) layer in a treatment bath. This treatment is followed by the 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) nitrate or a lead (II) salt of an amido, imido, nitrido or fluoro sulfate or phosphate. The treatment bath may be an aqueous solution of an organic titanium salt, the pickling solution, or the electrolyte. If the pickling solution is used for this purpose, the titanium body is anodically connected or the solution is oxygenated. If the electrolyte is utilized, Ti(IV) ions are introduced into that liquid in which the titanium body is immersed for an extended period before closure of the anodizing circuit.
