The world’s largest electric vehicle battery manufacturer is set to restart mining lithium at its major Jiangxi operation, creating fears that the market for the commodity will be flooded with supply at a time when prices are so low as to make many other ventures unprofitable.

Analysts at UBS, who first reported last year that CATL was suspending production in Jiangxi, last week said the company was in the process of resuming operations. The investment bank based that claim on information from the Shanghai Metals Market but provided no other details.
