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. The present report contains data regarding the film formation after storage at 71C and initial experiments towards the determination of the charge equivalent involved in the reduction of SOCl2. LiSOCl2 cells show large voltage delays due to Li electrode polarization after storage for 4 to 9 days at 71C under high purity conditions. Fresh Li electrodes can support large anodic current densities 200 mAsq cm. Stored electrodes showed low currents approximately 0.3 mAsq cm which are practically independent of electrode polarization between 0.5 and 3.0 V vs. Li. Electrolyte additives or substitution of Li by a LiSn alloy did not significantly alter the voltage delay behavior.
