Li-SO₂ Battery:

Lithium Sulfur Dioxide (Li-SO₂) Battery delivered a voltage of 2.9V. The batteries havea high energy density and a good capability for delivering repeated bursts of high power.This kind of cell is mainly used in defense applications, utility metering and etc.

Principle and Reactions:

The positive active material of Li-MnO₂ batteries is Manganese Dioxide (MnO₂) while negative active material is Lithium (Li).

Positive reaction   MnO₂ + Li+ + e- → MnO₂Li

Negative reaction   Li → Li+ + e-

Total reaction   MnO₂ + Li → MnO₂Li

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