Metal-air batteries

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

Q1: What is Lithium?

It is a chemical element with the symbol Li and atomic number 3. Classified as an alkali metal, lithium is a solid at room temperature. It is the lightest of the solid elements. It is soft, white, and lustrous. It reacts vigorously with water.
