Chery Unveils Breakthrough 600 Wh/kg Solid-State Battery Prototype

Chery has announced a major advance in solid-state battery technology, revealing its first self-developed battery module with an exceptional cell energy density of 600 Wh/kg — roughly double that of today’s leading lithium-ion systems.

The breakthrough, unveiled at a recent industry conference in China, could enable electric vehicles to achieve ranges of up to 1,500 km on a single charge (or around 1,300 km in real-world conditions). The milestone positions Chery among the global frontrunners in next-generation EV energy storage.

Developed by the Chery Solid-State Battery Research Institute, the new module uses an in-situ polymerized solid electrolyte combined with a lithium-rich manganese cathode, marking a step change in both safety and performance. Pilot operations are scheduled for 2026, followed by commercial rollout in 2027 under Chery’s new Kunpeng Battery Brand.

The announcement follows a series of rapid developments in China’s solid-state race. Axxiva, a Chery- and Gotion-backed manufacturer, began producing 300 Wh/kg solid-state prototypes in July, while Toyota, SK On, and Volkswagen are each accelerating parallel projects to close the gap to market readiness.

Chery’s progress signals growing momentum toward mass-market solid-state EVs, potentially transforming vehicle design, efficiency, and lifecycle economics — and underscoring China’s increasing dominance in advanced battery research and production.
