An all-inorganic electrolyte, lithium primary battery operable over the temperature range - 40 to 160F is being evaluated. The desired energy density is 150 watt-hours per pound of total battery weight and the desired power density is 50 watts per pound. Discharge characteristics of the LiLiAlCl4-SOCl2C system were obtained at -40, 72, and 160F. Chemical analysis of precipitates formed in carbon electrodes of cells discharged at ambient temperature provided information on reaction stoichiometry. For each equivalent of Li oxidized, one mole of LiCl precipitated in or on the carbon electrode. The weight gain of the carbon electrode was due solely to LiCl precipitation. No other insoluble salt was formed. There was evidence for sulfur formation on discharge at -40F. Pressures were observed when cells were discharged at 160F. They are higher than the expected SOCl2 vapor pressures, and result from gases not condensible at room temperature. Modified author abstract
