Hindustan Zinc to work on zinc based alternative to Li-ion batteries

Hindustan Zinc Limited, a major integrated zinc and silver producer, has announced plans to explore zinc applications in batteries. This initiative aligns with the company's efforts to support global energy transition and emerging clean technologies.

Zinc-based batteries are being presented as an alternative to lithium-ion batteries, with purported advantages in stability, safety, and cost-effectiveness. The company highlights that zinc is more abundant in India compared to lithium, which is largely imported.

Arun Misra, CEO of Hindustan Zinc, stated that the company is focusing on aiding global energy transition through sustainable energy sources. He mentioned a proposed partnership with US-based Aesir Tech, which specializes in zinc battery technology, and plans to explore research avenues with Indian academic institutions.

The company cites a Bloomberg NEF report projecting significant growth in the global energy storage market, reaching 442 GWh by 2030. Hindustan Zinc aims to contribute to this growth by leveraging its zinc reserves and expertise.

Various zinc-based battery chemistries are mentioned, including zinc-manganese, zinc-ion, nickel-zinc, and zinc-air. The company claims these batteries offer advantages such as flexibility, long cycle life, high energy density, and wide operating temperature range.

Hindustan Zinc emphasizes the environmental aspects of zinc-based batteries, stating they are recyclable, use non-hazardous materials, and have a lower greenhouse gas footprint compared to other technologies.

The company positions itself as a potential strategic partner in the transition to sustainable energy solutions, aiming to play a key role in the value chain of zinc-based battery technology. This initiative is presented as part of Hindustan Zinc's broader strategy to contribute to the development of clean technologies and meet the increasing demand for alternative energy solutions.
