Estonian Startup Claims Solid-State Battery Breakthrough
17 Jan
Summary
- Donut Lab announced production of solid-state batteries at CES 2026.
- The batteries offer 400 Wh/kg energy density and five-minute charging.
- Verge electric motorcycle uses the new battery technology, on sale now.
At CES 2026, Estonian startup Donut Lab claims to have achieved a significant breakthrough, announcing the production of solid-state batteries. These advanced batteries replace traditional liquid electrolytes with a solid material, offering a high energy density of 400 watt-hours per kilogram and a remarkable five-minute charging capability. The company asserts these batteries are also cheaper than current lithium-ion options and are resistant to thermal runaway.
Donut Lab's technology is already powering the Verge TS Pro electric motorcycle, which is now available for purchase with deliveries expected in the first quarter of 2026. While Verge advertises slower charging times for the motorcycle, the underlying battery technology promises exceptional performance and durability, with a claimed lifespan of 100,000 charge cycles. Other applications demonstrated included a "skateboard" platform for EVs and designs for battery-electric truck trailers.
Despite the bold claims, details on Donut Lab's specific methodology remain scarce, leading to industry skepticism given past failures in solid-state battery development. However, the imminent release of the Verge motorcycle provides a tangible opportunity for independent evaluation of the technology. While established companies and other startups continue their own solid-state research, Donut Lab's announcement represents a potentially disruptive shift in the electric vehicle battery landscape.
