Lithium Thionyl Chloride(Li-SOCl2) batteries have a high energy density, and its nominal voltage is 3.6V. Bobbin structure is best suit for low current discharge and spiral structure is best suited for high current discharge.

Principle and Reactions

The Li-SOCl2 battery uses liquid Thionyl Chloride (SOCl2) as its positive active material, and Lithium (Li) as its negative active material. The reactions of the batteries are shown below.

Positive reaction: 2SOCl2 + 4Li+ + 4e- →4LiCl + S + SO2

Negative reaction: Li → Li+ + e-

Total reaction: 2SOCl2+4Li → 4LiCl+ S + SO2
