CSIR (Council of Scientific & Industrial Research) has developed Zinc air batteries optimized for use in sub-zero conditions.
About Zinc Air Batteries:
- Zinc air batteries are a type of metal-air battery comprising a zinc negative electrode and an air (oxygen) positive electrode.
- The CSIR’s version integrates a highly efficient cathode catalyst with an anti-freezing electrolyte, specifically designed for zinc-air batteries.
- The battery employs a CoFe/Fe3C alloy/carbide hybrid structure, which significantly enhances its durability and efficacy across both liquid and solid-state zinc-air batteries.
Advantages:
- High Energy Density: Zinc air batteries exhibit a higher energy density compared to conventional lithium-ion batteries, making them more efficient for energy storage.
- Accessibility: These batteries utilize metals like zinc which are abundant in India, enhancing the feasibility and reducing dependence on imports.
- Cost-Effectiveness: The local production of these batteries decreases the overall costs associated with energy storage solutions.
- Environmental Friendliness: Zinc air batteries are recyclable, presenting a less hazardous alternative to traditional lithium-ion batteries.
- Flexibility and Portability: They are not only lightweight and compact but also flexible, making them ideal for use in remote and challenging environments.
Applications:
- Large-Scale Energy Storage: Zinc air batteries are used in stationary energy storage applications where large amounts of energy need to be stored and accessed.
- Transportation: These batteries can be integrated into various transportation means, offering a sustainable energy solution.
- Renewable Energy Systems: Their high scalability and energy density make them suitable for coupling with renewable energy sources, aiding in the efficient storage of renewable energy.
