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.
■Battery Reactions
Positive reaction:MnO2+Li++e-→MnOOLi
Negative reaction:Li →Li++e-
Total reaction: MnO2+Li →MnOOLi
Features
■Optimum for Memory and RTC Backup
Displays long-term stable operating voltage at low load discharge.
■High 3 volt energy density
High energy density.At 3 volts(nominal voltage),it has about twice the voltage of alkaline button batteries and silver oxide batteries.
■Stable discharge characteristics through low internal resistance and high operating voltage
Employs highly conductive electrolyte,lowering internal resistance and providing stable operating voltage.This allows stable power to be obtained,with little change in operating voltage at room temperature as well as high and low temperatures.Can be used in temperatures from -20 deg .C to+85 deg.C.
■Superior leakage resistance and excellent storage characteristics
Employs a leak-resistant organic electrolyte,giving it better leakage resistance than battery types using alkaline electrolytes.Furthermore,the high degree of seal of the seal structure and application of sealant keep self-discharge to about 1% per year.
■Superior high rate discharge characteristics
