On September 17, 2025, the solid-state battery concept sector witnessed a resurgence, with Weilai Lithium Chip's stock price soaring to hit the daily limit. Following suit, industry giants such as CATL and Sunwoda also experienced notable gains. SVOLT Energy Technology, a key player in the field, unveiled its ambitious R&D blueprint for solid-state batteries. The company aims to achieve a significant milestone by the end of 2025: completing the development of 10Ah-level, 400Wh/kg all-solid-state cells. Moving forward, in 2026, SVOLT plans to initiate the mass production ramp-up of its first-generation semi-solid-state batteries, while simultaneously advancing the development of second-generation 400Wh/kg products. By 2028, the company envisions introducing the third-generation 450Wh/kg semi-solid-state batteries, alongside embarking on the development of pure solid-state batteries boasting capacities exceeding 70Ah and energy densities of 500Wh/kg.

From a technological perspective, SVOLT Energy Technology has adopted a strategic approach of prioritizing semi-solid-state batteries before transitioning to all-solid-state solutions. Its independently developed electrolyte thermal composite transfer printing process has significantly enhanced electrolyte transfer efficiency, surpassing 95%. This innovative process is not only compatible with existing production lines but also enhances yield and safety. Currently, SVOLT Energy Technology has established a dedicated 2.3GWh production line specifically for semi-solid-state batteries. The first-generation 270Wh/kg square cells are slated for trial production in November 2025. These cutting-edge products have already secured orders from European automakers and are designated for use in eVTOL (electric Vertical Take-Off and Landing) projects of central enterprises.
