China’s Jiangxi province is poised to add 3 GWh of solid‐state battery production capacity through two major initiatives, reflecting the country’s growing emphasis on advanced battery technologies for electric vehicles.
On November 27, local authorities began reviewing a proposal for a 1 GWh solid‐state battery manufacturing facility led by a subsidiary of Pure Lithium New Energy. The planned plant will cover more than 68,000 square meters in a high-tech park in Huko County and is designed to produce state-of-the-art solid-state storage batteries for EV applications. According to public filings, small-scale testing of the cells is expected in 2026, with vehicle integration trials targeted for 2027. If successful, this project could represent one of the first full solid-state battery deployments in Chinese passenger cars.
Meanwhile, Sanwei Battery (Shaanxi) is investing approximately 17 billion yuan to build a 2 GWh solid‐state battery R&D and production complex in Jiangxi’s Yugan High-Tech Zone. The development plan includes a research center, a smart manufacturing base, and associated infrastructure, all aimed at supplying high-performance solid-state lithium batteries for electric mobility. Founded in late 2024, Sanwei Battery focuses on battery manufacturing, energy storage services, and electronic materials, including its own solid-state lithium battery line. Major stakeholders include Guorui Supply Chain Company and Sanwei Guoheng Battery Energy Technology Partnership.
Sanwei Battery is also expanding production capacity in other regions. In Zhangjiakou, Hebei province, construction is underway on a 1 GWh solid-state specialty battery facility within an automotive industrial park. In Longyan, Fujian province, a separate Sanwei subsidiary has secured environmental approval for another 1 GWh solid-state lithium battery project, further supporting EV adoption.
These Jiangxi developments come alongside large-scale cathode and cell projects in other provinces, such as a 40,000-ton lithium-iron/manganese phosphate (LMFP) cathode plant in Ya’an and a 3 GWh high-energy-density cylindrical cell line in Shandong. Together, these investments underscore China’s strategy to diversify and strengthen its electric-vehicle battery supply chain across multiple technologies and regions.
