The Canadian Armed Forces are interested in portable high energy density power sources such as the Li/SOCl2 system, which perform well over a broad range of temperatures. Typical applications would include the Chemical Agent Monitor and Search and Rescue Beacons. Previous work revealed a potential safety hazard after high-rate Li/SOCl2 cells were discharged on resistive load at -40C. Following extended periods of time on load, these cells exhibited overheating and a rapid internal pressure rise when allowed to warm up on open circuit. More detailed studies have since been performed on high-rate Li/SOCl2 cells from two manufacturers to further investigate this hazardous behaviour and to better define the conditions under which this behaviour occurs. Methods for chemical analysis of constituents were developed and used to investigate the physico-chemical basis for this undesirable low temperature behaviour.
