Dongfeng Solid-State Battery Roadmap Targets 50,000 Vehicles by 2027

Dongfeng Motor has outlined an ambitious development strategy for its solid-state battery technology, setting a goal of delivering 50,000 vehicles equipped with its internally developed batteries by 2027. The company also plans to introduce 100 demonstration vehicles before the end of this year, marking an important milestone in validating the technology before wider commercialization. These initiatives form part of a phased roadmap aimed at accelerating the adoption of next-generation electric vehicle batteries while maintaining complete in-house control over the underlying technologies.

Dongfeng Reveals Multi-Stage Commercialization Timeline

The production roadmap was presented by Zhang Wei, the new battery operations manager at the Advanced Technology Research Institute within Dongfeng Group's R&D Academy, during the 21st Shanghai International Automobile Manufacturing Technology & Equipment and Material Exhibition. According to the announced schedule, the company intends to introduce approximately 100 demonstration vehicles equipped with solid-state batteries by the end of this year. Around 2030, Dongfeng expects to begin small-scale mass production of solid-state battery vehicles, while widespread commercial deployment and large-scale manufacturing are targeted for approximately 2035.

Validation Progress Supports Production Readiness

Dongfeng confirmed that its solid-state battery program has entered a critical validation stage after successfully completing winter vehicle testing of its 350 Wh/kg battery earlier this year. The company expects to begin installing the battery in production vehicles during the fourth quarter. Zhang also stated that the 350 Wh/kg battery has already reached stable batch production, indicating that manufacturing processes have matured sufficiently to support the next phase of vehicle integration and demonstration activities.

Key Specifications of Dongfeng's Solid-State Battery

Complete In-House Technology Development

According to Zhang, every major element of the battery system has been developed internally by Dongfeng Motor. This includes the electrode materials, solid-state electrolyte technology, and complete battery pack integration. By maintaining control over these critical technologies, the company aims to strengthen product performance, accelerate future development cycles, and reduce reliance on external suppliers as commercialization expands.

Fast-Charging Battery Deployment Planned for 2027

Beyond its initial commercialization roadmap, Dongfeng also intends to introduce vehicles equipped with fast-charging solid-state batteries in 2027. During the same period, the company plans to begin pilot production of its 350 Wh/kg fast-charging battery. This initiative is expected to enhance charging convenience while supporting broader electric vehicle adoption through improved user experience and shorter charging times.

Advantages Over Conventional Lithium Batteries

Solid-state batteries are widely viewed across the automotive sector as the next evolution of electric vehicle energy storage. Compared with conventional liquid lithium batteries currently dominating the market, they are expected to provide higher energy density, extended driving range, and enhanced safety characteristics. Dongfeng previously stated that the energy density of its 350 Wh/kg battery is roughly twice that of mainstream lithium iron phosphate (LFP) cells, which typically deliver approximately 140 to 210 Wh/kg. The company also estimates that vehicles using this battery could travel more than 1,000 kilometers on a single charge, helping reduce concerns over driving range.

Infrastructure and Manufacturing Expansion

In June 2025, Dongfeng Motor completed and commissioned its dedicated solid-state battery laboratory while simultaneously bringing a 0.2 GWh pilot production line into operation in China. These investments provide the technical and manufacturing foundation needed to validate the technology, optimize production processes, and prepare for future scaling as the company advances toward its commercialization targets over the coming decade.
