Chinese battery maker Contemporary Amperex Technology Co. Ltd. said it has halted mining at its Jianxiawo project in Yichun, Jiangxi province, after the site’s permit expired on 9 August. The company, the world’s largest producer of electric-vehicle batteries, is applying to renew the licence and expects operations to remain suspended for at least three months. The mine can produce roughly 46,000 metric tons of lithium carbonate equivalent a year, or about 3 percent of projected global output in 2025, according to Australian government data. The stoppage is the first publicly disclosed in Yichun, China’s biggest lithium hub, and follows Beijing’s wider push to curb industrial overcapacity; officials recently ordered Zangge Mining to shut a site in Qinghai on similar grounds. News of CATL’s halt sent the most-active lithium carbonate contract on the Guangzhou Futures Exchange up the maximum 8 percent on Monday. Shares of lithium producers also rallied, with Hong Kong-listed Ganfeng Lithium climbing 20 percent and Tianqi Lithium rising 15 percent, while Australia’s Liontown Resources jumped 25 percent. U.S. miner Albemarle added more than 10 percent in early New York trading. Lithium prices have fallen almost 90 percent from their 2022 peak amid slowing electric-vehicle demand and a supply glut. Analysts said the Yichun shutdown eases some near-term oversupply pressures and could accelerate further capacity cuts if authorities press ahead with additional mine reviews across the region.
