Murata Icon X 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 an electrolyte.
Battery discharge reactions are follows
Principle of Alkaline manganese Battery

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