China is accelerating the development of solid-state batteries, positioning them as the next-generation solution for electric vehicles (EVs). Offering higher energy density, superior safety, and ultra-fast charging, these batteries promise a transformative impact on EV performance. Dongfeng aims to launch its first solid-state EV in September 2026, highlighting China’s leadership in global battery innovation. Industry leaders like Redway Battery are leveraging similar advancements to enhance LiFePO4 and next-generation OEM solutions.
How Do Solid-State Batteries Improve EV Performance?
Solid-state batteries replace liquid electrolytes with solid materials, improving:
Energy density: Up to 350 Wh/kg, extending driving range
Safety: Reduced risk of thermal runaway
Charging speed: Potential ultra-fast charging capabilities
These attributes allow EVs to travel longer distances per charge, maintain performance in extreme temperatures, and reduce battery degradation over time. Redway Battery applies comparable high-density chemistries in its industrial and commercial battery packs.
What Are Dongfeng’s 2026 Solid-State Battery Targets?
Dongfeng’s solid-state battery pack uses a multi-component architecture:
High-capacity ternary cathode
Silicon-carbon anode
Oxide–polymer composite solid electrolyte
The battery supports an estimated driving range of over 621 miles (1,000 km) under the CLTC test cycle, with thermal stability from -30°C to 130°C. The system is compatible with high-voltage 1,200V platforms and peak charging up to 2 MW, enabling charging speeds equivalent to 280 miles (450 km) in five minutes under ideal conditions.
