Svolt Debuts 80 kWh PHEV Battery Pack, Semi-Solid Battery Breakthroughs

At its sixth Battery Day held in Changzhou, Jiangsu province on January 13, 2026, Svolt Energy introduced an 80-kWh battery pack designed for plug-in hybrid electric vehicles (PHEVs). Described as the world’s largest capacity for a PHEV pack, the Fortress 2.0 system uses a highly integrated design that improves volume utilization and raises energy density by 6 percent. Its cells incorporate ultra-fast-charging graphite technology, enabling peak charging rates of up to 6C and allowing a 10–80% recharge in only ten minutes.

The company also shared updates on its semi-solid-state battery program. Its first-generation high-nickel semi-solid battery has entered limited production with an energy density of 270 Wh/kg and is already equipped in a European passenger car model. A second-generation high-nickel version, developed for low-altitude aircraft, achieves 342 Wh/kg and has finished installation and flight tests in an eVTOL aircraft. Meanwhile, a mid-nickel semi-solid battery aimed at mid- to high-end passenger cars is scheduled for mass production in October 2026, offering an energy density of 245 Wh/kg.

Additionally, Svolt launched its 3.5th-generation ion oscillation pulse charging technology, which reduces charging time by 25% compared to the prior generation without increasing cost. After accumulating over 20,000 hours of testing, this fast-charging solution is set to be adopted across multiple models on a customer’s new platform in the third quarter of 2026.

Financially, Svolt reported its first quarterly profit in Q4 2025 and is targeting full-year profitability in 2026. The company plans to ship 61 GWh of batteries in 2026, representing a 50% increase over the previous year.

Originally established as the battery unit of Great Wall Motor in 2012 and later spun off in 2018, Svolt focuses on next-generation materials, cells, modules, packs, BMS, and energy storage systems. According to the China Automotive Battery Innovation Alliance, Svolt ranked eighth in China for power battery installations in November 2025, with 2.45 GWh installed and a market share of 2.62%.
