Geely to Test Solid-State Battery With 621-Mile Range — Volvo EVs Could Be Next

Geely, the Chinese automotive conglomerate that owns Volvo, is preparing to put solid-state battery technology to the test on public roads. The company announced it will begin pilot deployment of its solid-state batteries across its portfolio of child brands starting in 2027, with Volvo potentially among the first to benefit.

The claimed specifications are impressive. Geely says it has achieved an energy density of 500 Wh/kg at the cell level — roughly double that of its current Golden Brick batteries. The range target exceeds 621 miles (1,000 kilometers) on a single charge, rivaling diesel-powered vehicles. Additionally, the battery is engineered to last more than 600,000 miles.

Solid-state batteries also offer advantages in weight reduction and use less volatile chemical compounds compared to conventional lithium-ion cells. While automakers have long promised solid-state breakthroughs as "just a few years away," Geely appears to be moving closer to real-world deployment. If successful, the technology could significantly reduce range anxiety for EV owners and mark a major step forward in battery development.
