Aluminium-Air Battery Technology

IEM design and manufactures Aluminium-Air Batteries. Through its cathode material manufacturing expertise, IEM added capability to design and manufacture aluminium-air battery to take advantage of this exciting emerging energy storage opportunity.  

An aluminium-air battery works by using aluminium as the anode and oxygen from the air and a reactive layer of carbon as the cathode. When the battery is in use, the aluminium anode reacts with the oxygen in the air to form aluminium hydroxide, releasing electrons in the process. These electrons flow through an external circuit, producing an electric current that can be used to power devices.

This reaction generates a voltage of around 1.2 to 1.4 volts, depending on the specific design of the battery. The aluminium anode is consumed during the reaction, so the anode will eventually need to be replaced once all the aluminium has been used up.

The key advantages of the Aluminium-air batteries:

• High energy density of 4.56 KWh per kg.
• Anode is extremely light (cathode is effectively reduced to a wire mesh and membrane layer).
• Safe and environmentally friendly since they do not produce harmful emissions.
