Dongfeng’s solid-state EV revealed with 2027 battery roadmap

Dongfeng has unveiled a “solid-state” electric car and, alongside it, mapped out a roadmap for next‑generation batteries. According to Dongfeng Headlines, the development team has already brought a semi‑solid battery to product readiness, while the main effort now focuses on fully solid‑state technology with series production targeted for 2027. The timeline puts the emphasis on near‑term industrialization rather than distant promises.

The photo in the release shows a prototype that visually echoes the eπ lineup (for example, the 007), though specific battery details for this car remain undisclosed. Earlier, the company showcased a bundle of technologies: high‑energy solid‑state cells and the Mach ultra‑high‑voltage platform. Taken together, that clearly points to a push for faster charging and higher overall efficiency.

Among the concrete milestones are a 0.2 GWh pilot line for solid‑state batteries and plans to fit cars with packs around 350 Wh/kg by September 2026 to help achieve roughly 1,000 km of range. In parallel, Dongfeng says it is developing a fast‑charging, fully solid‑state version at the 350 Wh/kg level with trial application slated for December 2027, and it has initiated preliminary work on sulfide full solid‑state cells aiming for 500 Wh/kg.

Testing results are highlighted separately: more than 72% energy retention at −30°C and successful passage of a 170°C thermal‑chamber test—figures that, the company notes, significantly exceed typical liquid ternary (NCM) batteries and the requirements of prevailing standards.
