Hindustan Zinc And JNCASR Advance Zinc?Ion Battery Prototypes

12 Feb 2026 CW Team

Zinc?ion batteries offer advantages for stationary applications because zinc is abundant and relatively low cost, and aqueous electrolytes reduce flammability risks compared with many lithium?ion chemistries. While current zinc?ion systems exhibit lower energy density than lithium?ion alternatives, the collaboration is addressing key material and electrolyte challenges to improve cycle life and performance for long?duration storage. The team is progressing work to enhance energy storage capacity and extend operational duration without compromising safety and scalability.

Hindustan Zinc supported researchers at the centre to develop the electrolyte formulations and assemble pouch cell prototypes, demonstrating applicability to renewable energy capture and release patterns typical of solar generation. The prototypes were tested under realistic conditions and showed promising stability and reliability for large?scale applications, indicating potential for further optimisation and commercialisation pathways. The collaboration emphasises industry–academia partnership as a means to strengthen indigenous capabilities and develop India?centric solutions for the clean energy transition.

Hindustan Zinc reiterated its intent to accelerate the shift towards sustainable energy solutions by developing next?generation zinc materials and storage technologies while continuing its core operations in metal production and supply. The company highlighted its market position and sustainability commitments as enabling factors for scaling such technologies and supporting wider renewable integration. Continued research and development is expected to refine performance metrics and prepare the technology for broader deployment.

Hindustan Zinc Limited, in collaboration with the Jawaharlal Nehru Centre for Advanced Scientific Research, has developed stable and reliable zinc?ion battery pouch cell prototypes aimed at large?scale renewable energy storage. The prototypes were formulated with low?cost electrolytes that improve stability and enable longer cycle life, and they were evaluated under realistic solar capture and release profiles to assess suitability for stationary deployment. The development marks a milestone in indigenous research on energy storage technologies and reflects a strategic effort to leverage domestic zinc resources for the energy transition.
