At CES 2026, Finnish startup Donut Lab made a bold announcement, introducing what it claims to be the “world’s first mass - producible all - solid - state battery.” The company asserts that it has the capability to produce the battery on a gigawatt - hour scale. As per the details provided, this battery boasts an impressive energy density of 400 watt - hours per kilogram. It can be rapidly charged within just 5 minutes, and after undergoing 100,000 charge cycles, it shows only minimal capacity degradation. Moreover, it retains over 99% of its capacity even when exposed to extreme temperature conditions, ranging from as low as - 30°C to over 100°C.

However, the lack of authoritative third - party test reports has cast a shadow of doubt over these claims. Donut Lab has clarified that its core materials and production processes are proprietary information and thus cannot be made public. The battery is unique in that it contains neither rare earths nor lithium. It follows a distinct technological path, and its production costs are on par with those of lithium iron phosphate batteries.

Currently, the battery has a production capacity of roughly 1 gigawatt - hour. The company has ambitious plans to ramp up this capacity to 20 - 30 gigawatt - hours by early next year. The battery is presently undergoing external independent testing, and the results are expected to be released in two weeks.

At the exhibition, Donut Lab’s parent company, Finnish Verge Motors, showcased the world’s first mass - produced electric motorcycle powered by this battery, the Verge TS Pro/Ultra. This motorcycle is set to be delivered in the first quarter of 2026. Staff members from the company hinted that detailed technical information about the battery might be disclosed after the delivery. The company anticipates having a lead time of approximately six months, and it has already secured patents to protect the relevant technology.
