Technical Specifications: Maxell Lithium Batteries [Coin Cell]

The Maxell coin-type lithium manganese dioxide 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 wrist watches, PDA's, key fob's, calculators, memory & RTC backup, and other portable electronic devices.

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.

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
