A Review of the Calcium Thionyl Chloride Electrochemical System
Abstract
Citing work from the open literature and from Government-sponsored contractual efforts, research on the calcium thionyl chloride electrochemical system is reviewed. Progress has been made toward enhancing the performance at 25 C by adding sulfur dioxide to the electrolyte, and by using cathodes comprised of a blend of high- and low-surface area carbons. Sulfur dioxide raised electrolyte conductivity and improved low-temperature (-30 C) performance; still, low-temperature capacity remains poor. With strontium tetrachloroaluminate salt in the electrolyte, the film that formed on calcium was altered, which reduced rapid corrosion of calcium effectively, especially when used in conjunction with sulfur dioxide. With careful engineering, this may be a viable system for special applications
