Alkaline Battery Discharge

Zn + 2MnO₂ + H₂O → ZnO + 2MnOOH

Genel Bakış

Alkaline batteries use zinc powder anode and MnO₂ cathode in potassium hydroxide electrolyte, producing 1.5 V. They offer 4–9 times the capacity of zinc-carbon cells for high-drain devices. The alkaline electrolyte provides lower internal resistance and better performance at high current.
