Dongfeng Motor has outlined a roadmap for deploying vehicles powered by its in-house solid-state batteries, targeting delivery of 50,000 units by 2027. Zhang Wei, battery operations manager at Dongfeng’s Advanced Technology Research Institute, unveiled the timeline at the 21st Shanghai International Automobile Manufacturing Technology & Equipment and Material Exhibition.
By the end of this year, Dongfeng plans to field 100 demonstration vehicles equipped with its solid-state battery systems. The company aims to initiate small-scale mass production around 2030 and to achieve large-scale output and widespread adoption by 2035.
Dongfeng’s solid-state battery technology recently entered a crucial validation phase. In January, the company completed winter vehicle testing of its 350 Wh/kg solid-state battery and plans to begin in-vehicle applications in the fourth quarter. According to Zhang, the 350 Wh/kg cell has reached stable batch production, and all key technologies—from electrode materials and solid-state electrolytes to full battery pack integration—were developed internally.
Looking ahead, Dongfeng intends to start pilot production of a fast-charging version of its 350 Wh/kg solid-state battery in 2027, aiming to reduce charging times while maintaining high energy density. Solid-state batteries are expected to deliver higher energy density, improved safety and extended driving range compared with conventional liquid-electrolyte cells. Dongfeng reports its 350 Wh/kg battery achieves roughly twice the energy density of typical lithium iron phosphate cells, supporting vehicle ranges of more than 1,000 kilometers on a single charge.
Since June 2025, Dongfeng’s solid-state battery laboratory has been operational, alongside a 0.2 GWh pilot production line. Other Chinese automakers and battery manufacturers are also preparing limited vehicle deployments of solid-state technology by 2027. However, industry experts note that several technical and manufacturing challenges must be overcome before full commercial rollout can occur.
