Abstract

The invention provides a method of making a cathode for an electrochemical cell which involves incorporating sodium chloride in dispersed form into an electrolyte permeable matrix and impregnating the matrix with a suitable sodium aluminum halide molten salt electrolyte. The matrix is formed from a transition metal selected from at least one member of the group consisting of Fe, Ni, Co, Cr and Mn, and the intermediate refractory hard metal compounds of said transition metals with at least one non-metal selected from the group consisting of carbon, silicon, boron, nitrogen and phosphorus.
