Context: The Council of Scientific and Industrial Research (CSIR) has developed a new battery designed to function effectively in sub-zero temperatures, which is particularly beneficial for defence forces and civilians in high-altitude regions.

  • The innovative battery features a durable cathode catalyst and an anti-freezing electrolyte, making it suitable for extreme cold conditions where conventional batteries fail.
  • Researchers at CSIR-Central Mechanical Engineering Research Institute created a hybrid cathode material combining cobalt and iron alloys with nanoparticles.
  • This enhancement improves the battery’s durability and performance in both liquid and solid-state zinc-air batteries, even in very low temperatures.
  • The new battery’s portability, flexibility, and lightweight nature make it a versatile energy solution for various users, including military personnel and remote communities.

The technology is part of a broader effort to develop efficient energy storage systems, addressing limitations of traditional lithium-ion batteries and exploring alternatives like metal-air batteries and electro-catalytic techniques for low carbon footprint solutions.
