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
