Dongfeng Schedules October Debut for 350 Wh/kg Semi-Solid Power Cell Ahead of Production Run
State-owned automaker Dongfeng Motor plans to present its proprietary 350 Wh/kg solid-liquid hybrid battery next month before initiating serial vehicle installations during the final quarter of 2026.
- 350 Wh/kg
- 170°C
- 72% (-30°C)
- 0.2 GWh
What Happened
Executive leadership at Dongfeng confirmed the operational timetable during a technical forum on September 9, stating that vehicle assembly lines will begin integrating the proprietary cells during the closing quarter of 2026.
Internal validation protocols demonstrated safety margins under severe thermal stress, with the architecture enduring a 170°C chamber exposure that cleared the official 130°C requirement. Sub-zero trials conducted during winter testing showed over 72% energy retention at -30°C.
Manufacturing operations rely on a 0.2 GWh pilot line commissioned in June 2025. Dongfeng targets putting 100 demonstration units into service before the end of 2026, ahead of delivering 50,000 vehicles in 2027 and advancing toward mass-scale all-solid-state production around 2030.
Why this matters
Chinese manufacturers are accelerating commercial deployments of semi-solid chemistry to achieve extended driving distance and cold-weather thermal resilience prior to the industrial arrival of pure solid-state cells slated for the next decade.
