About Metal-air batteries:

  • It is an energy storage system based on electrochemical charge/discharge reactions that occur between a positive “Air Electrode” (cathode) and a negative “Metal Electrode” (anode).
  • The negative electrode is typically made of metals such as Li, Zn, Al, Fe, or Na, while the positive usually contains some form of porous carbon material and a catalyst.
  • Advantages :
    • These batteries have higher energy density than a lithium-ion battery.
    • Accessibility: Metal-air batteries use readily available metals in India, making them more accessible than lithium-ion batteries.
    • Cost-Effective: Producing these batteries locally reduces imports.
    • Environment-Friendly: Metal-air batteries are recyclable, offering a safer alternative to lithium-ion batteries that pose environmental hazards.
    • Lightweight: Metals like aluminum are lightweight and can provide comparable or even higher energy density than lithium-ion batteries, making them an attractive choice.
  • Applications: Due to their high scalability and energy density, M-Air batteries can be used in a large variety of applications:
    • It is used in large-scale stationary energy storage applications
    • Transportation
    • Renewable generation
