[Solid-state battery: Qinghai's 3,000 mt per year lithium sulfide project completed filing]
[Solid-State Battery: Qinghai 3,000 mt/year Lithium Sulfide Project Completes Filing] On August 10, 2026, the Online Approval and Supervision Platform for Investment Projects in Qinghai Province showed that Qinghai Weixiang Technology Co., Ltd.'s 3,000 mt/year lithium sulfide project completed the filing of an enterprise investment project. The project is located on the north side of Hanhai Road, Kunlun Economic Development Zone, Golmud City, Qinghai Province, with a total investment of 81.319 million yuan. It mainly involves building a 3,000 mt/year lithium sulfide production line and related supporting facilities, to be implemented in two phases (Phase I: 500 mt/year, Phase II: 2,500 mt/year), and is also capable of producing 10,000 mt of lithium sulfate. It is planned to be completed in July 2027. The core technology, "preparation of high-purity lithium sulfide by high-temperature low-pressure method," has been granted a national invention patent, jointly developed by Qinghai Weixiang Technology and the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences.
