Reliance Industries Ltd. is in talks with Chinese battery behemoth CATL and other global suppliers to procure parts for battery energy storage systems, according to people familiar with the matter, as India’s largest company seeks to advance its renewable energy ambitions in the face of China’s tech curbs. The talks could pave the way for Reliance to have a second major source of battery components at its upcoming facility in Jamnagar, a city in the state of Gujarat, said the people, who asked not to be identified because the discussions are private. That could supplement supplies from Xiamen Hithium Energy Storage Technology Co. under a partnership that has run into roadblocks in recent months. The move comes after Reliance faced setbacks in fully accessing the technological know-how needed to produce lithium-ion battery cells. That has pushed the Indian conglomerate to focus more heavily on packaging pre-made cells into big battery systems as Beijing tightens controls on core battery technology exports.
