Lithium-Inorganic Electrolyte Batteries.
Abstract
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. Sulfur is a reaction product of Li/SOCl2 cells. Fifty percent (50%) of the total sulfur content of reacted SOCl2 is found by chemical analysis of elemental sulfur. Sulfur is quite soluble in the electrolyte. Analysis by gas chromatography indicates that SO2 is a reaction product, but no other major volatile products are formed. Reduction of SOCl2 on Ni, Pt, Au and C is a complex, potential dependent process. Surface layers are formed on all these electrodes and interfere with reduction of SOCl2. After high temperature storage, Li/SOCl2 batteries showed severe voltage delays and voltage depression due to Li electrode polarization. The protective film on Li breaks only locally leading to localized anodic Li dissolution at high current densities.
