Quick Takeaways
- Geely Auto solid-state battery development moves closer to in-house production and vehicle-level validation.
- The milestone highlights accelerating solid-state battery R&D across China’s electric vehicle industry.
Geely Auto is preparing to complete production of its first in-house developed all-solid-state battery pack in 2026, followed by vehicle installation verification. The update places the Geely Auto solid-state battery program among the most advanced initiatives announced by a Chinese automaker, reflecting intensifying competition in next-generation electric vehicle batteries.
The company shared this progress during Geely Holding Group’s five-year strategy communication, confirming that the initial all-solid-state battery pack has reached a stage suitable for production completion and real-vehicle evaluation. This step is critical for assessing safety, performance stability, and compatibility with future electric models.
Geely Auto solid-state battery roadmap and parallel innovations
Alongside its solid-state efforts, Geely Auto is also advancing a self-developed lithium manganese iron phosphate battery. The new chemistry is designed to deliver more than a 15% improvement in energy density, supporting longer driving range and better packaging efficiency without compromising cost control or durability.
These parallel developments underline a dual-track strategy: preparing for long-term solid-state adoption while continuing to enhance mature lithium-based technologies for nearer-term deployment.
Industry-wide progress among Chinese automakers
Several domestic manufacturers have already moved solid-state concepts into vehicle-level testing. Dongfeng Motor began extreme cold-weather testing of a solid-state battery prototype vehicle on January 14, with plans to start mass production of 350 Wh/kg solid-state batteries by September 2026, targeting a driving range of up to 1,000 kilometers.
At the end of last year, Hongqi under China FAW Group rolled out its first prototype vehicle equipped with solid-state batteries, formally entering the on-road testing phase for all-solid-state technology. These moves signal growing confidence among automakers in bringing laboratory advances closer to real-world conditions.
Battery makers take a more cautious stance
While vehicle manufacturers are announcing ambitious timelines, leading battery suppliers remain more conservative. CATL and BYD, the world’s two largest battery producers, currently aim for limited vehicle integration of solid-state batteries around 2027 rather than immediate large-scale commercialization.
Svolt Energy plans to complete development of its second-generation 400 Wh/kg semi-solid-state batteries in 2026, with higher-density 450 Wh/kg semi-solid-state pouch batteries expected by 2028.
As the Geely Auto solid-state battery program moves into production completion and validation, the contrast between automaker urgency and supplier caution highlights both the promise and the technical challenges that still define the path to widespread solid-state battery adoption.
