Battery Giant CATL Loses Environmental Permit at Jianxiawo, China's Largest Lithium Mine

The Yichun Ecology and Environment Bureau withdrew on August 26, 2026 the proposed acceptance notice for the environmental impact assessment covering the Jianxiawo lithium project in Jiangxi province, operated by Yichun Times New Energy Mining, a unit of battery maker CATL. The regulator acted after members of the public challenged the website used for the project's first public disclosure, a procedural requirement under Chinese environmental participation rules. The notice will only be reissued once the filing is confirmed as compliant. China's largest lithium mine by capacity is therefore back on care and maintenance, with no clear restart date.

Jianxiawo is a low grade lepidolite deposit with an average lithium oxide content of roughly 0.27 to 0.28 percent. Its nameplate capacity approaches 150,000 tonnes of lithium carbonate equivalent a year, which represented about 4 to 5 percent of world supply when the site ran at full rate. That scale is what turns a local permitting question into a global pricing question.

The disruption did not start this summer. Operations were suspended on August 10, 2025 when the original mining licence expired, after Beijing tightened mineral classification rules and reclassified the deposit from ceramic clay containing lithium to lithium ore. That reclassification forced CATL to rebuild its permit file from the ground up. A replacement licence covering lithium, ceramic clay, rubidium and caesium was granted on November 28, 2025 and runs to November 27, 2047. A land use pre-review permit followed on June 17, 2026, and a safety production permit was issued on June 29, 2026.

With the mining and safety approvals in hand, activity picked up again. Satellite imagery reviewed by Benchmark Mineral Intelligence showed work resuming at the site in June 2026, and a partial restart ran through July. That restart was informal and bypassed an unresolved dispute over the mine's tailings pond. More than 70 formal complaints reached regulators, and satellite tracking showed activity stopping again during the first week of August 2026. A revised environmental impact report had been published for public comment on July 27, 2026, opening the statutory consultation phase that has now been reset.

The content of that filing explains why a restart remains distant. It proposed annual ore output of 30 million tonnes, down about a third from the previous 45 million tonne rate, and covered the open pit, crushing and ore transport infrastructure. It excluded the associated processing plant and the tailings facility. Mined ore is not lithium carbonate, so Jianxiawo cannot return as a meaningful source of battery chemicals until extraction, mineral processing and waste management are all authorised and running at scale. The slowest permit in the chain now sets the timetable.

Benchmark responded by cutting its 2026 mined output forecast for the site to 32,000 tonnes of lithium carbonate equivalent from 62,500 tonnes, erasing 30,500 tonnes from the year. Its 2027 forecast is unchanged at roughly 99,000 tonnes. The downgrade reflects both the tonnes already lost during the shutdown and the risk that final approval slips into the fourth quarter of 2026 or beyond. Analysts consider a full review running into 2027 a realistic outcome.

The price reaction has been firm. Chinese lithium carbonate rallied through August 2026 as restart hopes faded, maintenance outages hit several lithium salt plants and inventories drew down. The most active contract on the Guangzhou Futures Exchange then eased 3.24 percent to 154,780 yuan a tonne on September 2, and traded near 152,000 yuan on September 4. That is roughly double the level of a year ago but well below the two year high above 200,000 yuan touched in mid May. There has been no repeat of the limit up move that followed the original 2025 suspension, because traders had already priced in a long delay.

Demand is strong. Lithium producer Albemarle told investors during its second quarter 2026 results that demand for stationary storage was off the charts, raised its storage forecasts by about 9 to 11 percent, and now expects stationary storage to account for roughly 30 percent of global lithium demand in 2026, close to parity with light duty electric vehicles. The company also flagged limited spodumene availability and slow lepidolite restarts as the two supply constraints it watches most closely. Data centre buildouts and grid scale battery projects are the main engines behind that shift.

The risk does not stop at one site. Other Jiangxi operations are expected to produce around 108,000 tonnes of lithium carbonate equivalent in 2026, and inspections there could uncover waste and tailings shortcomings similar to those found at Jianxiawo. Some producers may accelerate extraction to consume quotas that could otherwise expire, which would add volatility in both directions. On the supply side, higher prices have already brought idled Australian capacity back, with Mineral Resources restarting Bald Hill after an 18 month halt and Core Lithium restarting Finniss, while Australian government forecasts still point to demand growth above 11 percent a year through 2031 against supply growth near 10 percent.
