Svolt Energy unveiled an 80-kWh battery pack for plug-in hybrid electric vehicles (PHEVs) at its sixth Battery Day event in Changzhou, Jiangsu province on January 13, 2026. Claimed to be the world’s largest PHEV capacity, the Fortress 2.0 pack employs a highly integrated system design that boosts volume utilization and energy density by 6 percent. Its cells feature ultra-fast charging graphite technology, supporting peak charging rates of up to 6C and enabling a 10-to-80 percent recharge in just ten minutes.
At the event, Svolt provided updates on its semi-solid-state battery research and development. The first-generation high-nickel semi-solid battery has achieved small-scale production with an energy density of 270 Wh/kg and is already installed in a European passenger vehicle model. The second-generation high-nickel variant, designed for low-altitude aircraft, delivers 342 Wh/kg and has completed installation and flight testing in an eVTOL aircraft. A mid-nickel semi-solid battery targeting mid-to-high-end passenger vehicles will enter mass production in October 2026 with an energy density of 245 Wh/kg.
Svolt also introduced its 3.5th-generation ion oscillation pulse charging technology, which cuts charging time by 25 percent compared to the previous generation without raising costs. After more than 20,000 hours of cumulative testing, this fast-charging solution will be deployed across multiple models on a customer’s new platform in the third quarter of 2026.
On the financial front, Svolt recorded its first quarterly profit in the fourth quarter of 2025 and aims to achieve full-year profitability in 2026. The company plans to ship 61 GWh of batteries in 2026, a 50 percent increase over 2025.
Founded as the battery division of Great Wall Motor in 2012 and spun off in 2018, Svolt focuses on next-generation materials, cells, modules, packs, battery management systems, and energy storage. In November 2025, it ranked eighth in China for power battery installations, delivering 2.45 GWh and a 2.62 percent market share, according to the China Automotive Battery Innovation Alliance.
