Lithium – Thionyl Chloride (Li-SOCl₂)

Thionyl Chloride Lithium batteries (Li-SOCl₂) are non-rechargeable primary batteries that use thionyl chloride (SOCl₂) as the electrolyte and metallic lithium as the negative electrode. They are renowned for their very high energy density, low self-discharge rate, and ability to operate in extreme environments. These characteristics make them ideal for industrial applications, long-term measurement devices, smart meters, and aerospace.

Characteristics:

The highest energy density of all Lithium systems.
Very high cell voltage (3.6V).
Very wide operating temperature range (-60°C to +150°C).
Ideal for low consumption or long-term applications.

Examples:

SAFT LSH20, LS33600, LSH14, LS26500, LS17500, LS14500, LS14250.
