ABSTRACT:
An improved electrode assembly is provided for use in a cell for the production of metal by electrolytic reduction comprising a nonmetallic conductive electrode, such as a carbon electrode, having a top surface and a central current carrying support shaft received in a central bore extending axially downwardly from the top surface. Conductive fin assemblies extend radially from the central support shaft in the electrode, the fin assemblies comprising a plurality of gate members extending radially from the central shaft adjacent a top surface of the electrode and wing members extending from the gate members downwardly into the electrode from the top surface. Metal conductive means, comprising a metal which will not contaminate the molten salt bath, extend downwardly in the electrode beyond the depth of the central shaft and fin assemblies. Current passing to the electrode from the central shaft will, therefore, be distributed more evenly in the electrode to minimize the voltage drop in the electrode and permit the cell to run cooler and more efficiently. Preferably, at least some of the current distribution materials comprise the same metal being reduced in the electrolytic reduction cell.
