ALUMINIUM-AIR BATTERY

March 20, 2021

State-owned Indian Oil Corporation Ltd. has entered into a joint venture with Israel-based battery technology startup Phinergy to develop aluminium-air technology based battery systems for electric vehicles and stationary storage, as well as hydrogen storage solutions.

About:

  • Top automakers, including Maruti Suzuki and Ashok Leyland, have already signed letters of intent with the newly formed joint venture to commercially deploy the battery solutions produced by IOC Phinergy.

  • Aluminium-air batteries are said to be a lower cost and more energy-dense alternative to lithium-ion batteries which are currently in widespread use for electric vehicles in India.

  • Aluminium-air batteries utilise oxygen in the air which reacts with an aluminium hydroxide solution to oxidise the aluminium and produce electricity.

Benefits

  • Aluminium-air battery-based electric vehicles are expected to offer much greater range of 400 km or more per battery compared to lithium-ion batteries which currently offer a range of 150-200 kilometres per full charge.

  • The aluminium plate in an aluminium-air battery is converted into aluminium trihydroxide over time and that aluminium can be reclaimed from aluminium trihydroxide or even traded directly for industrial uses.

  • Aluminium-air based batteries are also expected to be significantly cheaper than lithium-ion batteries, thereby reducing the cost of electric vehicle.
