Vedanta Group company Hindustan Zinc Ltd, in collaboration with the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), developed advanced zinc-ion battery pouch cell prototypes designed for large-scale renewable energy storage applications. The breakthrough marks a major step forward in India’s indigenous energy storage research and strengthens the country’s push to build affordable, locally developed battery technologies.
Zinc-Ion Batteries Emerge as a Cost-Effective Alternative
As demand for grid-scale storage grows alongside renewable energy capacity, zinc-ion batteries are gaining traction as a safer and more economical alternative to conventional lithium-ion systems. Unlike lithium, zinc is abundant, widely available, and significantly cheaper. This makes zinc-ion technology particularly attractive for stationary energy storage applications such as solar and wind power integration, microgrids, and backup systems. Consequently, the technology offers both cost advantages and supply chain security, two critical factors for India’s energy transition.
Tackling Key Performance Challenges
However, improving cycle life, stability, and energy density remains a technical challenge for
zinc-based batteries. To address these issues, Hindustan Zinc and JNCASR are actively optimising electrode and electrolyte materials.
Through focused research, the team has developed:
*Low-cost electrolyte formulations
*Stable zinc-ion chemistries
*Prototype pouch cells suitable for scalable deployment
These advancements enhance battery durability and operational efficiency, making the technology viable for commercial-scale renewable energy storage.
Supporting Safe and Scalable Clean Energy Storage
By combining academic research with industry expertise, the partnership aims to deliver energy storage solutions that are not only affordable but also safe and sustainable. Zinc-ion systems inherently offer lower fire risks and improved environmental compatibility compared to many existing battery technologies. As a result, the prototypes demonstrate strong potential to support large renewable installations while ensuring operational reliability.
Leadership Perspective
Highlighting the significance of the collaboration, Arun Misra, CEO and Whole-Time Director, Hindustan Zinc, said “Our partnership with the Jawaharlal Nehru Centre for Advanced Scientific Research reflects our commitment to enabling safe, cost-effective, and scalable energy storage solutions that can support the growing integration of renewable energy,” he said.
Strengthening India’s Energy Storage Ecosystem
As reported by thehindubusinessline.com, overall, the development positions Hindustan Zinc and JNCASR at the forefront of next-generation battery innovation in India. As the country accelerates renewable energy deployment, indigenous zinc-ion technologies could play a vital role in building resilient, affordable, and sustainable energy storage infrastructure.
