Zinc - Air battery open circuit voltage for the 1.4 ~ 1.5V, there is button, cylindrical and square shapes, etc.. Zinc - Air battery can be made from a battery, rechargeable battery can also be made. Secondary battery generally used to replace zinc anode and electrolyte rechargeable mechanical methods.
Zinc - air battery than the energy of large, stable discharge voltage, cathode active material unlimited air source, the battery cost, but not in a confined or the use of hypoxic conditions. Wet cell storage performance were poor and usually only applies to continuous use of the apparatus.
Alkaline zinc - air battery expressions for: (-) Zn | NaOH (KOH) | O2 (C) (+)
Cell reaction: Zn + NaOH + O2 → Na2ZnO2 + H2O
Zinc - Application of a wider air battery, zinc-air button batteries have been a perfect substitute for zinc -batteries for hearing aids and other equipment, square and cylindrical zinc-air battery has been widely used in various lights.
