Steunenberg, R K; Martin, A E; Tomczuk, Z

A high-temperature, secondary electrochemical cell includes a negative electrode containing an alkali metal such as lithium, an electrolyte of molten salt containing ions of that alkali metal, and a positive electrode containing a mixture of metallic sulfides. The positive electrode composition is contained within a porous structure that permits permeation of molten electrolyte and includes a mixture of about 5 percent to 30 percent by weight Cu/sub 2/S in FeS. 5 tables, 4 figures.
