  • These batteries can be used for electric vehicles and stationary storage, as well as hydrogen storage solutions.
  • Downsides 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 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.
