Zinc Air Battery

Zinc Air Battery

Zinc air batteries is a metal-air battery powered by oxidizing zinc and oxygen from the air. These batteries have high energy densities and are relatively cheap to produce/manufacture. It can be used in hearing aids, film cameras, and electric car induction. A zinc air battery has a high amount of energy and weight more than other types of batteries since atmospheric air is one of its reactants.

Zinc air battery has a long shelf life if sealed to keep air out; even the smallest form of this battery, button battery can be stored for up to 3 years at room temperature if its seal is not removed. The shelf life of a zinc air battery is a function of its interaction with its environment.

The electrolyte loses water faster in conditions of high temperature and low humidity because the potassium hydroxide electrolyte is capable of absorbing moisture from the air and dissolving it. In very humid conditions excess water accumulates in the cell, flooding the cathode and destroying its active properties.

Potassium hydroxide also reacts with atmospheric carbon(iv)oxide; the formation of the carbonate reduces electrolyte conductivity. These batteries have high self-discharge once opened to air; the cell’s capacity is intended to be used within a few weeks. The formula for the formation of this battery is:

Anode: Zn + 4OH → Zn(OH)42− + 2e (E0 = -1.25 V)

Fluid: Zn(OH)42− → ZnO + H2O + 2OH

Cathode: 1/2 O2 + H2O + 2e → 2OH (E0 = 0.34 V pH=11)

Overall: 2Zn + O2 → 2ZnO (E0 = 1.59 V)

The zinc air battery is of two types, either primary (non-rechargeable) or secondary (rechargeable)
