Cell containing chalcogenide cathode, alkali metal anode and solid halo-aluminum alkali metal compound electrolyte

An electric current-producing cell from which a current may be drawn at a temperature below the melting point of the electrolyte, comprising:

• a. an alkali metal-containing anode;
• b. a cathode containing as its cathode-active material, one or more chalcogenides of the empirical formula:
• M'Z.sub.n
• wherein M' is one or more metals selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum and vanadium, wherein Z is one or more chalcogens selected from the group consisting of oxygen, sulfur, selenium and tellurium, and wherein n is a numerical value between about 1.8 and about 3.2;
• and
• c. a solid electrolyte consisting essentially of one or more compounds of the formula:
• MAlX.sub.4
• wherein M is an alkali metal and X is one or more halogens selected from the group consisting of chlorine, bromine and iodine.

An electric current-producing cell from which a current may be drawn at a temperature below the melting point of the electrolyte, comprising:
