Lithium Primary Solutions

p3Unlike the other chemistries, lithium primary is a family of chemistries that all use the chemically active metal lithium. There are currently 5 different lithium chemistries available.

However, lithium thionyl chloride has become the most important of these lithium chemistries over the last 20 years. The reasons speak for themselves; thionyl chloride cells have an incredible temperature range of -56 °C to +85 °C. Couple this with very low self-discharge that allows them to be used over a 20 year period and it’s obvious why these cells are essential for powering remote devices in the environment worldwide.

Excell also uses special thionyl chloride cells designed for the drilling companies in the oil industry. These cells are rated commonly to 150 °C but some models are rated for as high as 200 °C

Lithium cells utilize one of 3 different cell construction types. These types determine characteristics of cells including current capability, performance, self discharge, and cost. The common construction types are:
