Gasgoo Munich - China FAW Group has successfully rolled out the first prototype vehicle featuring its self-developed Hongqi all-solid-state battery, the company announced on Jan. 21. The milestone marks FAW's official entry into a new phase of real-vehicle testing and verification in this cutting-edge technology sector.
Following a 470-day intensive technical push, the R&D team has secured a series of phased breakthroughs across multiple core areas.
Efforts centered on the sulfide electrolyte system, basic 10Ah performance units, and the manufacturing process for 60Ah cells designed for automotive-grade applications.
The unit installed for validation is a 66Ah all-solid-state cell, which demonstrates exceptional safety. It successfully passed a thermal abuse test under extreme conditions of 200 degrees Celsius, exhibiting robust thermal stability and potential for high safety standards.
Concurrently, the sulfide electrolyte material achieved key performance gains, with ionic conductivity surpassing the industry-recognized high threshold of 10 millisiemens per centimeter (10 mS/cm). This lays a critical material foundation for enhancing the battery's rate performance and fast-charging potential.

All-solid-state batteries are widely regarded as a crucial technological direction for next-generation power batteries. By replacing traditional liquid electrolytes with solid ones, they theoretically offer significant improvements in energy density, safety, and lifespan.
FAW's prototype rollout signals that its sulfide-based all-solid-state battery technology has moved from laboratory research to vehicle integration and functional verification. The upcoming real-vehicle testing phase will focus on evaluating the battery system's overall performance, durability, and reliability under actual operating conditions—a critical step toward commercial application.
This achievement represents another significant milestone in FAW's independent innovation within core new energy technologies. As the global automotive and battery industries actively invest in all-solid-state battery R&D, initiating these real-vehicle tests will accelerate the verification and iteration of related technologies. It also accumulates valuable data and experience for future technological upgrades and product applications. Moving forward, FAW said it will continue to advance in-depth testing and optimization of the technology.
