Hindustan Zinc develops zinc-ion battery pouch cell prototypes for renewable energy storage

Hindustan Zinc in collaboration with the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), has developed stable and reliable zinc-ion battery pouch cell prototypes for large-scale renewable energy storage. This milestone marks a significant step in India's indigenous research on energy storage technologies.

Zinc-ion batteries are emerging as strong candidates for stationary energy storage due to the abundance, low cost, and wide availability of zinc resources. While optimizing electrode and electrolyte materials to achieve longer cycle life and higher energy density remains a key challenge, the collaboration between Hindustan Zinc and JNCASR is addressing this by developing low-cost electrolyte formulations and stable zinc-ion battery prototypes suitable for large-scale deployment. These advancements demonstrate the potential of zinc-ion batteries to support renewable energy storage safely and efficiently.

Through this collaboration, JNCASR researchers, supported by Hindustan Zinc, are developing low-cost electrolyte formulations and building zinc-ion battery pouch cell prototypes. The newly formulated electrolytes improve stability and enable longer cycle life. The prototypes have been evaluated under realistic testing conditions, such as solar energy capture and release profiles, demonstrating their suitability for renewable energy applications.

While zinc-ion batteries currently have lower performance metrics than lithium-ion batteries, they offer distinct advantages, including exceptional safety, lower material costs, and non flammable aqueous electrolytes, key attributes for large-scale and long-duration deployment.
