ABSTRACT:
An improved electrically conductive current collector suitable for use in high temperature applications in the presence of corrosive environments comprising: (A) a high strength, noncorrosive electronically conductive ceramic member which serves as the primary load bearing element for said current collector; and (b) a highly electronically conductive metal cladding intimately attached to a substantial portion of ore surface of said ceramic member and adapted to direct current flow through said ceramic member and to shunt said current between said member and an external contact. The disclosed current collectors are ideally suited for use as current collectors and current collector/containers for electrical conversion devices such as the sodium/sulfur battery and the like. Also disclosed are two processes for preparing tantalum or niobium doped rutile titanium dioxide. The electronically conductive ceramics produced using these methods are ideally suited for use as the ceramic in the disclosed current collector.
