Aluminium-air battery

Date: 23 March 2021 Tags: Energy

Issue

Indian Oil Corporation has started into a joint venture with Israel-based start-up Phinergy to develop aluminium-air technology based battery systems.

 

Background

The electric vehicle segment in India is highly unexplored due to lack of recharge infrastructure. The new technology is expected to boost mobility.

 

Details

  • Companies like Maruti Suzuki and Ashok Leyland have already signed letters of intent with the joint venture to commercially use the battery solutions produced by the company.

  • Aluminium-air batteries lower the cost and are more energy-dense compared to lithium-ion batteries which are currently in use for Indian electric vehicles. 

  • An aluminium-air battery undertakes use of oxygen in the air which reacts with an aluminium hydroxide solution to oxidise the aluminium to produce electricity. 

 

Advantages

  • Aluminium-air battery-based electric vehicles offer much greater range of 400 km or more per battery compared to lithium-ion batteries.

  • They will reduce our dependency on Chinese imported Lithium-ion batteries.

  • After the battery life, the aluminium present in the aluminium-ion battery can be harvested to be used in other industries.

  • Aluminium-air based batteries are cheaper than lithium-ion batteries, thereby reducing the final cost of electric vehicle.

 

Drawbacks

  • One of the major drawbacks of aluminium-air batteries is that they cannot be recharged like lithium-ion batteries.

  • Large scale utilisation of aluminium-air battery based vehicles would need the wide availability of battery swapping stations.
