The objective of this program is to develop an all-inorganic electrolyte primary D cell which is storable and operable in the temperature range of -40 to 160 C and is capable of delivering in excess of 150 WHrlb at the thirty hours rate and at a peak power density of 50 wattslb. The hermetic LiSOCl2 D cell developed by us met all the objectives in terms of fresh performance. However, on storage the cells displayed a voltage delay. In addition, the cells exhibited explosion hazards on abuse. The results to date are encouraging in that new approaches may be found to alleviate the voltage-delay problem based on the information on the growth and morphology of the anode film.
