ABSTRACT:
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.
