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

Principle and Reactions:
The positive active material of Li-SOCl2 batteries is liquid Thionyl Chloride (SOCl2) while negative active material is Lithium (Li).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
