Lithium Thionyl Chloride Batteries

Lithium primary batteries, such as Lithium Thionyl Chloride, offer high energy density, extremely long shelf life (two to three times that of Alkaline), a wide operating temperature range, and excellent durability. With cell voltages of 3.0 to 3.6 volts, they provide much higher energy density than Alkaline. Lithium primaries also come in a variety of sizes. As with their rechargeable counterparts, they are subject to shipping regulations.

Lithium primary batteries are available in many chemistries, each with their own particular attributes. Specifically, Lithium Thionyl Chloride (LiSOCl2) cells have the highest energy density of all Lithium types. Service life is typically 15 to 20 years. These cells are best suited for applications having low continuous-current and moderate pulse-current requirements. Their long service life and low self-discharge rate make them ideally suited for use in harsh or inaccessible environments like utility monitoring, electronic toll collection, downhole data logging and meteorology.
