LiSOCL2
(Thionyl Chloride)

Introduction
Lithium-thionyl chloride cell was invented by Adam Heller in 1973. Lithium-thionyl chloride batteries are generally not sold to the consumer market, and find more use in commercial/industrial: automatic meter reading (AMR), medical: automatic external defibrillators (AEDs) applications and several others. The electrolyte chemistry below isn’t rechargeable. The cell contains a liquid mixture of thionyl chloride (SOCl2), lithium tetrachloroaluminate (LiAlCl and niobium pentachloride (NbCl) which act as the catholyte, electrolyte, electron sink, and dendrite preventive during reverse voltage condition, electrolyte, respectively. A porous carbon material serves as a cathode current collector which receives electrons from the external circuit. Lithium-thionyl chloride batteries are well suited to extremely low-current or moderate pulse applications where a service life of up to 40 years is necessary. Bobbin type batteries are more suited for highest possible charge capacity whereas spiral type is better choice for high pulse current needs.
