Principle and Reactions
The coin type lithium manganese dioxide battery uses manganese dioxide (MnO2) as its positive active material, lithium (Li) as its negative active material, and an organic electrolyte.
|Positive reaction ：
||MnO2+Li++e- -> MnOOLi
|Negative reaction ：
||Li -> Li++e-
|Total reaction ：
||MnO2+Li -> MnOOLi
Advantages of Lithium Coin Cell Batteries:
- High, 3.0V energy density. They have about twice the nominal voltage of alkaline and silver oxide button batteries.
- Stable discharge characteristics through low internal resistance and high operating voltage. Their design employs a highly conductive electrolyte, which lowers internal resistance and provides a stable operating voltage. This allows for a constant power, with little change in operating voltage over a wide wide of operating temperatures from -20C to +85C.
- Superior leakage resistance and excellent storage characteristics. They employ a leak-resistant organic electrolyte, superior to other battery systems using alkaline electrolytes. The high effectiveness of the seal structure and application of sealant keep self-discharge to minimal amount of about 1% per year.
- Superior high rate discharge characteristics. Optimum for memory and RTC backup displays. Long-term, stable operating voltage at low load discharge.
