- The Hongqi prototype demonstrates high safety, strong thermal stability, and advanced sulfide electrolyte performance.
On Jan. 21, China FAW Group announced the rollout of its first prototype vehicle equipped with a self-developed Hongqi all-solid-state battery, marking a decisive step in the company’s next-generation new energy strategy. The milestone confirms the transition of the China FAW Group solid-state battery program from laboratory development to real-vehicle testing and verification.
China FAW Group Solid-State Battery Development Breakthroughs
After 470 days of focused technical development, FAW’s research and development team achieved multiple phased breakthroughs across key technology domains. Work concentrated on advancing the sulfide electrolyte system, validating 10Ah performance units, and establishing manufacturing processes suitable for automotive-grade 60Ah cells, ensuring scalability and consistency.
High-Safety Performance Validated in Extreme Conditions
The validation unit installed in the prototype vehicle is a 66Ah all-solid-state cell designed to meet demanding automotive safety standards. During testing, the cell successfully withstood thermal abuse at temperatures reaching 200 degrees Celsius, demonstrating strong thermal stability and reinforcing its potential for high-safety electric vehicle applications.
Sulfide Electrolyte Achieves Industry-Leading Conductivity
Significant progress was also achieved in electrolyte materials. The sulfide electrolyte developed by FAW recorded ionic conductivity exceeding 10 millisiemens per centimeter, a benchmark widely recognized as a high-performance threshold. This advancement provides a strong foundation for improved charge rates, enhanced power output, and future fast-charging capability.
Role of All-Solid-State Batteries in Next-Generation EVs
All-solid-state batteries are widely viewed as a core technological direction for future power batteries. By replacing liquid electrolytes with solid materials, these systems are expected to deliver higher energy density, enhanced safety characteristics, and longer operational life compared to conventional lithium-ion batteries.
Vehicle Integration Marks Commercial Readiness Progress
The successful prototype rollout confirms that FAW’s sulfide-based all-solid-state battery technology has progressed beyond experimental research into vehicle-level integration and functional validation. The upcoming testing phase will focus on system-level performance, durability, and reliability under real-world operating conditions, a crucial step toward commercial deployment.
This development represents another major milestone in FAW’s independent innovation in new energy technologies. As global automakers and battery suppliers accelerate investment in solid-state solutions, FAW stated it will continue comprehensive testing and optimization to support future technology upgrades and product applications.
