ELECTRODE ENDUITE DE PLOMB OU D'UN ALLIAGE DE PLOMB ET METHODE DE FABRICATION

ELECTRODE COATED WITH LEAD OR A LEAD ALLOY AND METHOD OF MANUFACTURE ABSTRACT An electrode in particular an oxygen-evolving anode for metalelectrowinning from an acid electrolyte comprises a body of aluminium orother metal coated with lead or a lead alloy by electroplating preferablyfrom a non-aqueous electrolyte. The substrate can be a sheet ofaluminium or compacted particles of aluminium plated with lead or a leadalloy. A sheet of lead or lead alloy is clad to the electroplated substrateand advantageously an electrocatalytic material such as surface-activatedvalve metal sponge is applied to the surface of the lead or lead alloy sheet.
