Reliance plans to use Faradion’s technology at its proposed energy storage giga-factory, which is part of Dhirubhai Ambani Green Energy Giga Complex project located at Jamnagar in western India.

Reliance Industries chairman Mukesh Ambani said: “We welcome Faradion and its experienced team to Reliance family. This will further strengthen and build upon our ambition to create one of the most advanced and integrated New Energy ecosystem and put India at the forefront of leading battery technologies.

“The sodium-ion technology developed by Faradion provides a globally leading energy storage and battery solution which is safe, sustainable, provides high energy density and is significantly cost competitive. In addition, it has wide use applications from mobility to grid scale storage and back-up power.”
