Principle and Reactions

The cylindrical type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material and lithium (Li) as its negative active material.

Battery Reactions
Positive reaction :MnO2+Li++e- → MnOOLi
Negative reaction :Li → Li++e-
Total reaction :MnO2+Li → MnOOLi

Safety precautions

If misused, this battery may deform, leak (the liquid inside the battery may leak to the outside), generate heat, explode, or ignite.
Since such misuse may cause injury or equipment failure, please be sure to read and observe [Warnings and Cautions].
