Abstract
A method of making a catalytic lead-based oxygen-evolving anode comprises catalytically activating titanium sponge particles larger than 300 microns by impregnating with a solution containing Mn and Ru compounds, in amounts corresponding to Mn/Ru in an atomic ratio between 70/30 and 90/10, and thermally converting the compounds to an electrocatalyst comprising Mn and Ru in oxide form. Catalytic Ti sponge particles with up to 3 wt % Ru are thus produced, which are then uniformly distributed on the surface of a lead anode base in an amount greater than 400 g/m.sup.2, pressed, and partly embedded, thereby firmly anchoring and electrically connecting them to the lead anode base. The catalytic lead-based anode thus produced operates with oxygen evolution on the catalytic particles at a reduced potential at which the lead base remains electrochemically inactive. It thereby operates with significant energy savings over an extended service life.
