ABSTRACT:
An improved electrode assembly is disclosed for use in electrolytic cells for producing metal by the electrolysis of a molten-salt electrolyte. The electrode assembly includes at least one anode and cathode disposed within an electrolytic cell in a spaced-relationship to thereby define an inter-electrode space and an effective electrolyte bath area. The parallel, opposed sides of the anode and cathode defining the inter-electrode space of the improved electrode assembly have an offset, sawtooth pattern of triangular peaks and valleys to thereby increase the effective electrode surface area and to facilitate the rapid, effective removal of gas produced during electrolysis from the anode and from the inter-electrode, electrolyte bath area. To further facilitate the removal of such gases, the anode of the present invention includes a uniformly distributed plurality of gas evacuation apertures therethrough.
