 LiMNO2 Battery Advantages

Lithium Manganese Dioxide Battery (Li-MnO2 battery) has two different types, cylindrical type and Soft flat type. It is a high-reliability and lightweight battery with an operating voltage of 3V. And it has the ability to operate over a wide temperature range. It has a wide range of applications, both for powering devices, security equipment and can be used in all types of electronic devices.

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-CR123A Battery 3.0V CR17335 lithium manganese dioxide battery(li-mno2 battery) primary 1400mah Disposable Batteries for Gas Water Meter(图3)

Total reaction: MnO2 + Li → MnO2Li
