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. At all temperatures, capacity is limited by polarization of the carbon electrode. Prolonged storage at 160F results in severe voltage delays and lower steady-state discharge voltages upon discharge at room temperature. Both the voltage delays and the lower discharge voltages are attributable to polarization of the Li electrode. Corrosion of Li in SOCl2 is more severe in practical stainless steel cells than in glass containers under high purity conditions. Reduction of SOCl2 on Ni, stainless steel, or C is a complex, potential dependent process. LiCl is a major constituent of electrode surface films formed upon reduction in SOCl2/LiAlCl4 solutions.
