Chery's Rhino S Solid-State Battery Targets 808-Mile Range with 2027 Production Launch

Chery introduced its groundbreaking Rhino S all-solid-state battery technology at the 2025 Global Innovation Conference, a development poised to significantly alter the electric vehicle landscape by addressing range anxiety. The technology boasts an exceptional energy density of 600 Watt-hours per kilogram (Wh/kg). This metric suggests that electric vehicles equipped with the Rhino S could achieve driving distances of up to 1,300 kilometers, or approximately 808 miles, on a single charge. This achievement positions Chery to potentially leapfrog current industry roadmaps for next-generation power sources.

The technical foundation of the Rhino S centers on an in-situ polymerized solid electrolyte system, which is engineered to optimize charge carrier flow. This system works in tandem with a lithium-rich manganese cathode. The combination is credited with markedly improving ion conductivity and reducing ion transfer time, which are crucial for reaching such high energy density levels. Furthermore, the solid-state design, which replaces conventional flammable liquid electrolytes, contributes to improved thermal stability and safety, with tests reportedly showing no fire or overheating even after mechanical damage.

Chery has established a clear timeline for bringing this innovation to market, signaling a rapid transition from laboratory success to consumer application. The company plans to commence small-scale validation trials in 2026. The ultimate objective is to transition the Rhino S technology into large-scale production and vehicle integration by 2027. This aggressive schedule directly challenges established battery sector leaders such as CATL and BYD.

The company has declared its ambition to evolve from being primarily a "battery user" to a "battery definer," indicating an intent to become a major force in core battery technology rather than just vehicle assembly. While the potential range increase is substantial, industry analysts note that cost remains a significant hurdle, as solid-state batteries currently cost considerably more to produce than existing lithium-ion counterparts. Nevertheless, if successfully industrialized, the 600 Wh/kg density of the Rhino S would place Chery at the forefront of the next-generation EV power race.
