What is Lithium Thionyl Chloride (Li/SOCl2) Battery

Lithium thionyl chloride (Li/SOCl2) battery is a battery with the highest specific energy in the practical battery series. This highest specific energy value was obtained from a large-capacity, low-discharge-rate, large-size battery.

Li/SOCl2 batteries are fabricated in a wide variety of sizes and configurations, with capacities ranging from as low as 400mAh in cylindrical carbon-coated and wound electrode structures, to up to 10,000Ah in prismatic cells and many special requirements for special requirements size and construction of batteries. The Li/SOCl2 system originally has problems of safety and voltage hysteresis, among which safety problems are particularly prone to occur during high discharge rate discharge and overdischarge, and when the battery is stored at high temperature and continues to discharge at low temperature, the phenomenon of voltage hysteresis appears obviously.
