Chinese automaker Dongfeng Motor is preparing to enter a new phase of electric vehicle development with plans to mass-produce solid-state batteries in the second half of 2026.
The technology, if successfully commercialised, could significantly improve the safety, range, and performance of next-generation new energy vehicles (NEVs).
The company’s solid-state battery reportedly achieves an energy density of 350 Wh/kg, enabling electric vehicles to exceed 1,000 kilometers of driving range on a single charge.
Unlike conventional lithium-ion batteries that rely on flammable liquid electrolytes, Dongfeng’s design uses a solid electrolyte, reducing the risk of fire and explosion during overheating or collision.
Safety testing has been a major focus. The batteries are said to remain operational even after being compressed by 50% and show no signs of smoke or fire when exposed to temperatures as high as 170°C.
In cold-climate trials conducted in Mohe, the battery retained over 74% capacity at -30°C, demonstrating strong low-temperature resilience.
Dongfeng has adopted an oxide–polymer composite approach, which is widely considered one of the more commercially viable solid-state pathways due to its compatibility with existing manufacturing infrastructure.
The company also claims full in-house control of core technologies, including electrodes, solid electrolytes, and system integration.
The race toward solid-state batteries is intensifying across China’s automotive industry. Major competitors such as CATL, GAC Group, and FAW Group are also targeting commercialization between 2026 and 2027.
With strong backing from industry partnerships and rapid R&D progress, Dongfeng aims to further advance fast-charging capabilities and higher energy density designs beyond 2027.
If successful, these developments could help reshape the competitive landscape of global electric mobility.
