Background

With the accelerated global energy transition, solid-state batteries have become the core direction of next-generation energy storage technology. As the most promising technology route, sulfide solid-state batteries, with their near-liquid electrolyte ionic conductivity and wide electrochemical window, have become a key path to overcome the energy density bottleneck of existing liquid lithium batteries.

Applications such as EVs,  eVTOL, and energy storage provide enormous market potential for solid-state batteries. In Nov. 2025, the BMW Group announced a collaboration with Samsung SDI and Solid Power to jointly advance the research of sulfide all-solid-state batteries; in Nov. 2025, the first phase (0.5GWh) of SEVC POWER’s sulfide solid-state battery project went into production, becoming the first dedicated production base for aviation power batteries in Southwest China; in Nov. 2025, the 200MW/800MW semi-solid-state battery energy storage power station project in Wuhai City was successfully connected to the grid.

Lithium sulfide, as a key raw material for sulfide solid-state batteries, has made significant progress in low-cost, large-scale production. In Aug. 2025, SEMCROP completed the construction of its 100t-level high-purity lithium sulfide pilot line, and its 10t-level sulfide solid electrolyte production line went into operation and was ready to ship. In Sep. 2025, Tianqi Lithium's 50t/a lithium sulfide pilot project was substantially launched and construction began. In Oct. 2025, CATL invested in Canmax, further strengthening its presence in the solid-state battery materials field. In Nov. 2025, Zijin Mining signed agreements with Foshan Plastics Technology and Guangxin Holdings Group to expand its high-purity lithium sulfide industry.

China has formed a complete industrial chain in the field of sulfide solid-state batteries, from basic research to engineering applications. However, challenges such as cost reduction and efficiency improvement of high-purity lithium sulfide, interfacial compatibility between sulfide electrolytes and electrodes, and balancing battery cycle life and safety remain key bottlenecks that need to be overcome for industrialization.

The 2nd Lithium Sulfide & Sulfide Solid-State Battery Forum, hosted by ASIACHEM, will be held in Wuxi on March 26-27, 2026. It will bring together leading research institutions and leading companies in the industry chain to focus on the innovation of sulfide solid-state battery materials, process optimization and industrialization path, and explore how to break through key technical bottlenecks such as high-purity lithium sulfide synthesis, electrolyte-air stability improvement, anode adaptation and solid-solid interface control, so as to promote the commercialization of sulfide solid-state batteries.
