Abstract

Tests were conducted to determine the performance, storability, and safety characteristics for specially designed Li/Cl2 in SO2Cl2 (Li/CSC) cells at temperatures as high as 150° C. Discharge tests at 150° C showed that practical Li/CSC D cells yield energy densities of 0.75 to 0.91 Wh cm−3 for constant resistive loads of 3.0 to 75.0 ohms, respectively. Further, the performance results obtained for cells stored at 150° C and either discharged at 25° C or discharged at 150° C showed little loss in realized capacity but exhibited a noted loss in rate capability. These cells have been subjected to abusive conditions such as short circuit, forced overdischarge, incineration, puncture, and shock sensitivity testing following prolonged discharge at both ambient and elevated temperatures. Safety/hazard testing has also included specific combinations of the above abusive conditions. The results relative to the safe, efficient use of the cells at elevated as well as room temperatures will be discussed.
