1. SUBJECT
This specification presents typical and guaranteed ex-work values of the Lithium Manganese Dioxide Button Cells (Li / MnO2), of Model CR2032
Manganese dioxide (MnO2) is used for the active cathode material, and high voltage, high activity lithium metal for the anode material. Battery discharge reactions are as follows:
Anode reaction: | MnO2 +Li+ +e- | -> | MnOOLi |
Cathode reaction: | Li | -> | Li+ +e- |
Total reaction: | MnO2 +Li | -> | MnOOLi |
