Chinese Automakers Begin Mass Production of Solid-State EVs, Claiming 1,000 km Range and 5-Minute Charging

The era of the 1,000-kilometer electric vehicle is moving from the laboratory to the driveway. Chinese automakers, led by Dongfeng, Changan, and GAC, have officially commenced mass production of solid-state batteries, promising to eliminate range anxiety and slash charging times to just five minutes.[1][3]

For the everyday car buyer, the abstract science of battery chemistry translates into a very practical reality: road trips without mandatory hour-long charging stops, and winter driving without watching the battery gauge plummet. It changes the math for families deciding whether their next primary vehicle can be electric.[1]

Dongfeng Motor has confirmed that its 350 Wh/kg solid-state battery will enter mass production in September 2026. The company has already fired up a 0.2 GWh pilot production line, preparing to equip passenger vehicles with packs capable of exceeding 620 miles on a single charge.[1][4]

The charging speed fundamentally alters the rhythm of a road trip. Dongfeng's 1200-volt ultra-high-voltage platform allows drivers to add roughly 280 miles (450 kilometers) of range in just five minutes. That is less time than it takes to order a coffee, effectively matching the convenience of a traditional gas station fill-up.[1][4]

Traditional lithium-ion batteries rely on a liquid electrolyte, which can be heavy, temperature-sensitive, and prone to fire risks. Solid-state technology replaces that liquid with a solid material, drastically increasing energy density while virtually eliminating the risk of combustion—a major selling point for homeowners parking these vehicles in attached garages.[3][5]

For drivers in colder climates, the shift is particularly meaningful. During extreme cold-weather testing in Mohe, China, Dongfeng's solid-state prototype retained over 74% of its charge at temperatures plunging to -30°C (-22°F), meaning winter commutes no longer require a drastic reduction in expected range.[3]

Dongfeng is not acting alone in this market shift. Changan Automobile plans to deploy its "Golden Bell" solid-state battery in vehicles by the end of the third quarter of 2026, while GAC Group is gearing up to equip its Hyper-branded EVs with similar technology.[2][6]

Because solid-state batteries are significantly more energy-dense, they are also lighter. Dongfeng's new battery pack is reportedly 30% lighter than traditional lithium-ion counterparts, which improves vehicle handling, reduces tire wear, and frees up interior cabin space for passengers.[3][5]

As these vehicles roll out across China, the pressure mounts on Western legacy automakers to accelerate their own solid-state timelines. For consumers globally, the mass production of this technology signals that the biggest compromises of EV ownership are rapidly becoming a thing of the past, making the switch to electric a matter of preference rather than compromise.[2][5]
