What is Aluminum Air battery Technology?

The aluminum-air battery uses high-purity aluminum (containing 99.99% aluminum) as the negative electrode, oxygen as the positive electrode, and potassium hydroxide (KOH)  aqueous solution as the electrolyte. Aluminum absorbs oxygen in the air, produces a chemical reaction to discharge, and converts aluminum and oxygen into aluminum oxide. The progress of aluminum-air battery is very rapid, and its application in EV has achieved good results. It is a promising air battery.

Aluminium has around 3kWh/kg of electrical energy available when reacted with Oxygen. Aluminium is a solid, safe repository of electrical power that has a well-developed manufacturing and distributio infrastructure. It is the most abundant metal on Earth and is recyclable, low cost, lightweight and non-flammable.

The three basic parts to an Aluminium-Air Cell are:

1. The aluminium anode

2. An air-breathing membrane

3. An electrolyte liquid between them
