Abstract : Results are presented on high temperature solid state cells employing 50:50 weight percent lithium germanium vanadium oxide-lithium iodide. The incorporation of lithium iodide in lithium germanium vanadium oxide resulted in higher pellet conductivities and improved the high rate performance of the solid state cells. The cells were comprised of a lithium-aluminum or lithium-silicon alloy as the anode and a CVD thin film of titanium disulfide as the cathode. The cells exhibited an open circuit potential of about 2.1 V at 300 deg C and could be discharged at current densities up to 0.5 ampere per square centimeter. jg
