Lithium Thionyl Chloride (Li-SOCl2)

Lithium Thionyl Chloride BatteriesLithium-thionyl chloride cells have a metallic lithium anode and a liquid cathode comprising a porous carbon current collector filled with SOCl2. They deliver a voltage of 3.6V. There are cylindrical and button shape, from 1/2AA to D format, with spiral type for high current and bobbin construction for small current. Lithium-thiony chloride cells have a high energy density, partly because of their high nominal voltage of 3.6V. Bobbin type can reach 760Wh/kg, for a capacity of19Ah at 3.6V in D format. Because self-discharge is extremely low, this kind of cell can support long storage periods and achieve a service life of 10 to 20 years.
