Pelletized single cell experiments have been conducted to develop a family of potential cathode for a new, low temperature thermal battery system. The cells utilize a 60.2 ao lithium-aluminum alloy anode and a molten salt electrolyte of NaC1-saturated A1C13. They operate at temperatures between 175 and 250 C. A total of 40 sulfides, oxides, and halides were evaluated and compared to the molybdenum V chloride and copper II chloride cathodes previously studied. Of this group, three halides, WC16, FeC13, and TeC14, exhibited long discharge lifetimes, high available energy density, and high voltages under load. Various brands of graphite, acetylene black, and various types of metallic current collectors also were evaluated for performance enhancement. Author
