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.
