Sealed Primary Lithium-Inorganic Electrolyte Cell.
Abstract
The Li/SOCl2 hermetic D cell developed by P.R. Mallory and Co., Inc. met or exceeded all the initial objectives of an E.D. of 150 W-hr/lb at the thirty-hour rate and a peak power density of 50 watts/lb and the storage and operating temperatures of -40 to 160 deg F. However, the cells showed severe voltage-delays at -30 deg C after storage at 72 deg C, particularly at high rates. This problem was investigated in detail and severals methods were given for alleviating this problem. The lowering of the salt concentration in the electrolyte from 1.8(M) to 0.5(M) LiAlCl4-SOCl2 appeared to be an effective way to alleviate the voltage-delay problem. This also resulted in an increase in the intrinsic energy density of the cell.
