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.
MnO2+Li++e- -> MnOOLi

Advantages of Maxell 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.
