CR Primary Battery
Coin Type Lithium Manganese Dioxide Battery
Overview
The coin type lithium manganese dioxide battery (CR battery) is a small, lightweight battery with an operating voltage of 3V and the ability to operate over a wide temperature range. It has a wide range of applications, both for powering devices such as wristwatches and electronic calculators and can be used in all types of electronic devices mainly as memory and RTC backup.
Principle and Reactions
The coin type lithium manganese dioxide battery uses manganese Example of Typical Construction Negative Electrode (Lithium) dioxide (MnO2) as its positive active material, lithium (Li) as its negative active material, and an organic electrolyte solution.
