The Chatterjee Group (TCG) may consider commercial production of sodium-ion batteries, focusing on manufacturing cells.

Developed by TCG's Research Institute for Sustainable Energy (RISE), these batteries are made entirely from India-sourced materials. They can charge up to 94 percent in just five minutes and offer an energy density of 180 Wh/kg, comparable to leading lithium-iron phosphate batteries. The battery technology, free of cobalt, nickel, copper, and lithium, reduces India’s reliance on global supply chains for critical materials. The potential market for sodium-ion batteries is strong, particularly in electric mobility, grid-scale storage, and off-grid systems. 

The commercial rollout, with an investment of USD 10–12 billion, could happen within two to three years, depending on the development of the domestic supply chain. TCG CREST, a recently recognised deemed-to-be university, is also exploring green hydrogen systems for sustainable energy solutions.
