Svolt Energy has announced plans to begin volume deliveries of its first-generation semi-solid-state batteries in 2026, positioning the company among the latest Chinese manufacturers to commercialize this technology. At the 2025 World Power Battery Conference on November 12, Yang Hongxin, Svolt’s chairman and CEO, confirmed that these square-format cells, developed to achieve an energy density of 270 Wh/kg, are set to enter C-sample batch trial production ahead of mass rollout next year.
According to a company presentation released on November 15, orders for the initial semi-solid-state cells have already been placed by a leading European electric vehicle brand. In addition, the batteries will be integrated into an electric vertical takeoff and landing (eVTOL) project led by a Chinese state-owned enterprise. To support production, Svolt has established a dedicated semi-solid-state battery line with an annual capacity of 2.3 GWh.
Looking beyond first-generation cells, Svolt is developing a second-generation semi-solid-state design targeting 400 Wh/kg, with plans to introduce pouch-cell variants capable of 450 Wh/kg by 2028. The company highlights that conventional ternary lithium batteries—despite their prevalence in high-end EVs—account for a significant share of thermal runaway incidents. Svolt’s semi-solid-state technology addresses these safety concerns by incorporating non-flammable, non-corrosive solid electrolytes, which enhance thermal stability without compromising performance or increasing production costs.
Earlier reports indicated that Svolt would commence trial production of a 140 Ah version of its first-generation semi-solid-state cell in the fourth quarter, with mass supply slated for 2027 to a next-generation model of a well-known European compact car brand.
At the same conference, Dongfeng Motor announced it expects to start mass production of solid-state batteries with an energy density of 350 Wh/kg in September 2026, supported by a 0.2 GWh pilot line and targeting a driving range of up to 1,000 kilometers.
Since its spin-off from Great Wall Motors in early 2018, Svolt has expanded its portfolio to include battery materials, cells, modules, packs, battery management systems, and energy storage solutions. Data from the China Automotive Battery Innovation Alliance show that Svolt installed 2.27 GWh of capacity in October, capturing 2.71 percent of the domestic power battery market and placing seventh nationwide.
