On November 13th, at the 2025 World Power Battery Conference, Dongfeng Motor showcased its new generation of high-energy-density solid-state batteries and Mach-speed ultra-1000V pure electric platform, along with several self-developed new energy vehicle models, comprehensively demonstrating its innovative achievements and strategic layout in the new energy field. Dongfeng Motor stated that a 0.2GWh solid-state battery pilot production line has been built and put into operation, and it is expected that the 350Wh/kg solid-state battery will enter mass production and be applied to vehicles in September 2026, contributing to a vehicle range of 1000km.
The 350Wh/kg solid-state battery launched by Dongfeng Motor this time has an energy density far exceeding the current ceiling level of approximately 250Wh/kg for liquid lithium batteries. In practical applications, this means that electric vehicles equipped with this battery will easily achieve a range exceeding 1000 kilometers, maintaining over 72% range even in low-temperature winter conditions, far surpassing the 60% level of ordinary liquid ternary batteries.
Regarding safety performance, the battery successfully passed the 170℃ hot box safety test, significantly exceeding the national standard requirement of 130℃. It also demonstrated excellent safety characteristics in extreme tests such as puncture and compression, providing consumers with stronger protection.
The Mach-level ultra-1000V pure electric platform, launched simultaneously with the solid-state battery, constitutes Dongfeng's technological powerhouse. This platform adopts a 1200V ultra-high voltage architecture, equipped with Dongfeng's self-developed 1700V silicon carbide power module, combined with 12C supercharging composite cells and a single-gun 2MW charging pile, enabling a charging experience of "2.5 kilometers of charging in 1 second and 450 kilometers of replenishment in 5 minutes." This replenishment speed surpasses the convenience of refueling traditional gasoline vehicles; users only need a short rest at a service area to replenish most of the battery.
Dongfeng Motor's breakthrough in solid-state batteries is built on entirely independent R&D. From material systems and cell structures to manufacturing processes, Dongfeng has built a complete, self-controllable supply chain system, mastering core technologies such as electrolytes, separators, and in-situ curing. This full-chain technology control gives Dongfeng full autonomy in the evolution of battery technology.
Technology R&D began in 2018 with the establishment of the solid-state battery project team. After years of accumulation, a 0.2GWh solid-state battery pilot line has been built and put into use. Dongfeng has also laid out a three-generation solid-state battery technology roadmap, demonstrating a systematic long-term plan. In addition to the soon-to-be-mass-produced 350Wh/kg battery, Dongfeng will also develop a fast-charging 350Wh/kg all-solid-state battery, planned for pilot application in December 2027. Simultaneously, pre-research work has been carried out on a sulfide all-solid-state battery with an energy density of 500Wh/kg.
The mass production and application of solid-state batteries in vehicles will fundamentally change the user experience of electric vehicles. A practical range of 1000 kilometers means months of uninterrupted urban commuting and no need for recharging during intercity trips; its excellent performance even in extremely cold environments solves the winter driving concerns of users in northern regions; and its rapid recharging speed eliminates users' "range anxiety."
With Dongfeng's 350Wh/kg solid-state battery set to enter mass production and be deployed in vehicles next September, along with the application of its supporting ultra-1000V platform technology, the new energy vehicle industry is ushering in a new turning point. This technological breakthrough not only demonstrates the progress of Chinese automakers in core electric vehicle technologies but also has the potential to reshape the competitive landscape of the future electric vehicle market.
