The present invention is directed to an electric current-producing cell which contains an anode, a cathode, and an electrolyte. The anode has as its anode-active material one or more alkali metals. The cathode has as its cathode-active material one or more compounds selected from the group consisting of chalcogenide compounds having the formula M/sub a/FeX/sub b/ wherein M is a metal selected from the group consisting of sodium, potassium, rubidium, cesium, calcium, strontium, and barium, wherein X is a chalcogen selected from sulfur and selenium, wherein a is a numerical value of about 0.5 when M is a divalent metal and a is a numerical value of about 1 when M is a monovalent metal, and wherein b is a numerical value of about 2; and the above species of chalcogenide compounds of formula exhibiting alkali metal incorporation. The electrolyte is chemically inert with respect to the anode and cathode and permits the migration of ions between the anode and cathode.
