The Chatterjee Group Plans $10-12 Billion Investment in Indigenous High-Speed Sodium-Ion Batteries

Overview

The Chatterjee Group is considering commercial production of indigenous sodium-ion batteries developed by its research arm, TCG CREST. These batteries charge rapidly (94% in five minutes) and use India-sourced materials, avoiding critical metals like lithium and cobalt. The group may invest $10–12 billion, aiming to reduce India’s import dependence, particularly from China, and cater to electric mobility and energy storage needs.
