Dongfeng Motor 350 Wh/kg Battery Targets 2026 Vehicle Launch

Dongfeng Sets October Battery Unveiling

Dongfeng Motor 350 Wh/kg battery is set for an October unveiling before installation in mass-produced vehicles during the fourth quarter of 2026. Dongfeng deputy general manager You Zheng announced the schedule at an industry forum on Wednesday, September 9, according to local media outlet Cailian. The brief report did not provide additional technical details, but the timing broadly follows the company's earlier roadmap. Dongfeng said last November that it planned to start installing the 350 Wh/kg battery in mass-produced vehicles in September 2026, making the latest schedule a modest adjustment from the previous target.

Battery Terminology Shifts to Solid-Liquid Hybrid

The battery's terminology has also changed since Dongfeng's earlier announcements. The company previously described the product as a solid-state battery, but now identifies it as a "solid-liquid hybrid battery." The change reflects China's broader use of the term for semi-solid-state batteries, helping distinguish them from all-solid-state batteries. This distinction is important because Dongfeng's current product is being positioned for earlier vehicle deployment, while its separate all-solid-state battery program has a substantially longer commercialization timeline. The revised terminology therefore clarifies the technology's position without changing the company's stated 350 Wh/kg energy-density target.

Energy Density and Driving Range Targets

Dongfeng Motor has said the 350 Wh/kg battery reaches roughly twice the energy density of mainstream lithium iron phosphate, or LFP, cells, which typically range from 140 to 210 Wh/kg. The company has also stated that the battery can support more than 1,000 kilometers of driving range on a single charge. Those figures are central to Dongfeng's case for bringing the technology into production vehicles, although the available report does not identify the specific vehicle models, pack configurations, or test-cycle conditions associated with the range claim.

Safety and Cold-Weather Validation

Safety and low-temperature performance have been part of the battery's validation program. Dongfeng said the battery passed a 170°C thermal chamber test, exceeding the 130°C requirement under China's national standard. It also retained more than 72% of its energy at -30°C. In January, Dongfeng completed winter vehicle testing, with test vehicles traveling from Wuhan to Mohe in Heilongjiang province. The program included more than 70 tests conducted at temperatures between -40°C and -30°C, providing a broad cold-weather evaluation of the technology before its planned vehicle deployment.

Pilot Production and Vehicle Demonstration Plans

Dongfeng Motor has already established pilot manufacturing capacity for the battery technology. Its 0.2 GWh pilot production line was completed and began operating in June 2025, forming an integrated research and production base that combines laboratories, prototype production, and pilot manufacturing. The immediate priority is demonstration operation rather than full-scale commercialization. Dongfeng plans to deploy 100 demonstration vehicles equipped with the battery by the end of 2026 and has said it intends to deliver 50,000 vehicles using its in-house solid-state batteries in 2027.

Longer-Term All-Solid-State Battery Roadmap

The company's roadmap extends beyond the semi-solid, or solid-liquid hybrid, battery planned for near-term deployment. Dongfeng aims to begin small-scale mass production of all-solid-state batteries around 2030, followed by large-scale mass production and wider adoption around 2035. At the same time, it is developing a 350 Wh/kg all-solid-state battery designed to support fast charging and conducting preliminary research into sulfide-based all-solid-state batteries with an energy density of 500 Wh/kg. These programs indicate that Dongfeng is pursuing multiple solid-state battery pathways with different commercialization horizons.

Chinese Automakers Follow Different Deployment Timelines

Other automakers and battery suppliers in China are also moving toward solid-state battery deployment, although their schedules differ. China FAW Group's Hongqi brand rolled out its first prototype vehicle equipped with a solid-state battery earlier this year. Chery plans to equip vehicles with solid-liquid hybrid batteries in the fourth quarter of 2026 and begin vehicle testing of all-solid-state batteries in 2027. Meanwhile, CATL and BYD are taking a more cautious approach, with both targeting small-batch vehicle deployment in 2027. The differing timelines highlight an emerging race to move advanced battery technologies from validation into production.

Industry Impact & Outlook

Dongfeng's 2026 deployment schedule could give the company an earlier opportunity to gather real-world operating data from a larger demonstration fleet while preparing for broader vehicle integration in 2027. The significance will depend on how consistently the battery delivers its stated energy density, range, safety performance, and cold-weather capability in production conditions. The company's pilot line, demonstration plan, and longer-term all-solid-state programs also provide a staged path from pilot manufacturing to wider commercialization, while competing automakers and battery makers pursue their own timelines in China's rapidly developing advanced-battery market.

Frequently Asked Questions

When will Dongfeng install its 350 Wh/kg battery in vehicles?
Dongfeng plans to unveil the 350 Wh/kg battery in October and begin installing it in mass-produced vehicles during the fourth quarter of 2026. The schedule follows an earlier target of September 2026 for vehicle installation. Dongfeng also plans to deploy 100 demonstration vehicles equipped with the battery by the end of 2026 and deliver 50,000 vehicles using its in-house solid-state batteries in 2027. The company has separately outlined longer-term plans for all-solid-state battery production beginning around 2030.
