Dongfeng Motor Corporation recently announced that all testing and pilot production phases for its independently developed next-generation solid-state batteries have been successfully completed, with mass production and vehicle integration scheduled for the second half of 2026. Featuring fully localized core technologies, these batteries offer significant advantages in driving range, low-temperature adaptability, safety, and weight reduction, marking a major leap forward in the commercialization of solid-state battery technology.

Compared to the prevalent liquid lithium-ion batteries in today’s market, Dongfeng’s new-generation solid-state batteries fundamentally eliminate flammable and volatile liquid electrolytes, opting instead for highly thermally stable solid-state electrolytes. This change substantially reduces the risk of thermal runaway and fire hazards. According to official test data, the batteries exhibit exceptional safety performance: even when compressed to more than half their original size, they continue to function normally; when exposed to continuous baking at 170°C, they remain non-flammable and non-explosive. These results far exceed current national safety standards, directly addressing consumers’ top concerns regarding battery safety.

For daily vehicle users, driving range and low-temperature performance are of paramount importance, and Dongfeng’s solid-state batteries deliver outstanding results in these areas. With an energy density of 350Wh/kg, new energy vehicles equipped with these batteries can achieve a full-charge range exceeding 1,000 kilometers. Furthermore, the entire battery pack is 30% lighter than traditional lithium-ion batteries, effectively controlling overall vehicle weight while enhancing range, energy efficiency, and handling performance.  

To verify reliability under extreme conditions, Dongfeng conducted special cold-weather tests in Mohe earlier this year using experimental vehicles equipped with solid-state batteries, completing over 70 low-temperature operational validations.

Test results reveal that in frigid environments as low as minus 30°C, the batteries maintain a remaining charge retention rate above 74%, with low-temperature performance improved by over 10% compared to traditional liquid batteries. This effectively addresses the common issue of significant range reduction in electric vehicles during winter in northern regions.

According to publicly available information, Dongfeng’s solid-state battery laboratory and 0.2GWh pilot production line became operational in 2025, establishing a comprehensive “laboratory-pilot line-medium-scale production line” R&D and production system. This lays a solid foundation for subsequent mass production. Dongfeng Motor officially stated that, from electrode materials and solid-state electrolytes to battery pack integration, these solid-state batteries have achieved 100% independent R&D of core technologies, with full control over the entire technology chain, eliminating reliance on external technologies.

In terms of industrial collaboration, in May 2026, Dongfeng Motor took the lead in establishing the Hubei Province Solid-State Battery Industry Technology Innovation Consortium, in partnership with 18 university-enterprise units, including Wuhan University and Huazhong University of Science and Technology. This consortium integrates resources from industry, academia, and research to accelerate technology iteration and large-scale implementation, driving the overall development of the solid-state battery industry chain.

It is understood that Dongfeng’s technological R&D efforts extend beyond current products. At this stage, the R&D team has initiated research on fast-charging solid-state batteries and higher energy density battery technologies, with plans to introduce the next generation of high-specific-energy batteries and complete vehicle integration applications by 2027.

As a cutting-edge field in new energy power batteries, the commercialization of solid-state batteries has been a focal point of industry attention. Dongfeng’s decision to commence mass production and vehicle integration of its next-generation solid-state batteries in the second half of this year signifies that domestically produced solid-state batteries have officially entered the stage of large-scale application.
