Aluminium Air Batteries

Aluminium Air Batteries

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

  • These batteries utilise oxygen in the air which reacts with an aluminium hydroxide solution to oxidise the aluminium and produce electricity.
  • These batteries are said to be a lower-cost and more energy-dense alternative to lithium-ion batteries, which are currently in use in India.
  • These batteries can be used for electric vehicles and stationary storage, as well as hydrogen storage solutions.
  • The downside of aluminium-air batteries is that they cannot be recharged like lithium-ion batteries. So, large-scale use of these battery-based vehicles requires several battery swapping stations.
  • Aluminium plates in the aluminium-air battery is converted into aluminium trihydroxide over time and that aluminium can be reclaimed or even traded directly from it for industrial uses.
