Abstract

The addition of cathode materials comprising Cu.sup.++, Fe.sup.+++, Cr.sup.+++ or Au.sup.+++, in the form of salts such as the nitrate or halide, e.g. Fe(NO.sub.3).sub.3 or CuCl.sub.2, to low melting nitrate electrolyte cells increases cell potential. Other ions such as Co.sup.++, Eu.sup.+++, La.sup.+++, Ni.sup.++, Mn.sup.++, Ce.sup.+++, Pr.sup.+++, Nd.sup.+++, Gd.sup.+++, Sm.sup.+++ and Tb.sup.+++, in the form of salts thereof, can also be used, but yield smaller cell potentials. Such cathodic materials in the form of a suitable salt, such as a nitrate or halide, e.g. Fe(NO.sub.3).sub.3 or CuCl.sub.2, are added to low melting fused nitrate electrolytes, e.g. a LiNO.sub.3, KNO.sub.3 mixture, in a concentration sufficient to increase cell potential, using Li or Ca anodes. A suitable metal current collector such as a Ni screen can be used as a cathode. The above cathodic materials can be used in conjunction with other cathodic materials such as AgNO.sub.3, which undergoes reduction to the free metal.
