[Solid-State Battery: Capchem Expected to Post a Preliminary Profit of 970 Million–1.03 Billion Yuan in H1, with Electrolyte Price Increases Contributing to Earnings]

On 21 August 2026, the State Administration for Market Regulation (SAMR) announced that China’s proposed international standard proposal, Application guide, test items and conditions for solid‑state batteries for secondary lithium‑ion batteries for electric vehicle propulsion, was successfully initiated at the International Electrotechnical Commission (IEC).

LG Energy Solution said solid-state batteries are likely to be commercialized first in small IT devices such as smartphones rather than electric vehicles, citing technical barriers in scaling up and mass production. According to U.S. automotive media outlet InsideEVs on August 24, the head of LG Energy Solution’s North America business made the remarks during a press briefing for local media following the opening ceremony of the company’s Lansing plant in Michigan. “The problem with solid-state batteries is large-scale production,” he said, adding that while their high energy density makes them feasible for small form factors, most companies face difficulties when trying to produce very large form factors. He added that solid-state batteries will likely be seen in smartphones about 10 years before they appear in EVs, and that they are expected to be applied first in specialized use cases before being deemed suitable for EVs or ESS.

[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.
