High Rate Li/SOC1(2) Cells. II. Effect of Catalyst on Cell Performance

摘要

As part of the ongoing High Energy Batteries for Weapons Programs at NSWC, various cell parameters were investigated to examine their effect on the performance, safety, and chemistry of Li/SOC12 cells. This report summarizes the influence of cobalt dibenzo-tetraazaannulene (Co-TAA) cataylsis on the discharge and overdischarge chemistry and performance of spirally wound commercial C-size cells. Co-TAA catalyst improved the performance and safety of C-size Li/SOC12 cells. The catalyst was most effective at high rate or low temperature operation. The presence of water increased the risk of hazards at high rates of discharge. The generation of gases such as COS, CS2, HC1, etc. was dependent on the internal temperature. Originator supplied keywords include: Lithium Battery, Catalyst, Tetraazaannulene, Thionyl Chloride.
