A composite electrode having a structural electrode member with at least a portion of one surface of the electrode member constructed from a continuous matrix of an anodically passivatable metal infiltrated by a metal capable of forming an electroconductive oxide and having the infiltrating metal at the electrode surface oxidized such that an electric current path is provided through the oxidized surface of the matrix metal. In one embodiment the matrix metal is an electrochemical valve metal, e.g., titanium and the infiltrating metal is lead. Applications for the composite electrode include battery grids and electrochemical processing electrodes.

A bipolar electrode support structure for use in a lead acid battery is constituted by a porous matrix of valve metal, impregnated with lead or a lead alloy, and is provided on at least one surface thereof with a rim-portion at which little or no lead is exposed. The rim-portion is used to maintain an electrolyte-tight seal in operation.

A negative lead-acid storage battery electrode having a base made of a porous, sintered metal lighter than lead infiltrated with lead, lead alloy or a metal wetted by pure lead in the molten state. The base is then provided with a protective layer of pure lead and negative active mass atop the pure lead layer.
