Lithium Thionyl Chloride

Thionyl chloride-lithium cells have the highest energy density of all lithium types and are manufactured in welded, hermetically sealed cases. Service life is an unmatched 15 to 20 years and holds for all case types---cylindrical and coin or wafer. The cells are best suited for applications having very low continuous-current and moderate pulse-current requirements. Their extremely long service life and low self-discharge rate make them ideal where physical access is limited, such as for remote sensing systems.

Lithium battery chemistries differ in several important characteristics. Remote wireless-sensing applications are also ideal for lithium primary batteries. For example, wireless passive infrared (PIR) sensors used in security systems typically draw very small currents (tens of uA) in quiescent mode and 7.5 mA to 10 mA when transmitting. Under those operating conditions, a thionyl chloride/lithium cell offers a service life up to 2-1/2 times longer than either a poly (carbon monofluoride) or manganese-dioxide lithium cell of the same size.
