Principle of Alkaline manganese Battery

Manganese dioxide (MnO2) is used for the active cathode material, and specially processed fine zinc-alloy powder is used for the active anode material. Potassium hydroxide is used as a electrolyte.

Battery discharge reactions are follows

With open circuit voltage of approx. 1.50V, the battery voltage is extremely stable and impedance remains low during discharge.
