Solid-state battery from Donut Lab is reported to be in production now.

At CES 2026 Donut Lab's CEO Marko Lehtimaki said the company's solid-state cells are in production in Finland with initial capacity of about 1 gigawatt-hour, and the company provided claims about higher energy density, faster charging, and long cycle life.

Donut Lab announced at CES 2026 that its so-called Donut Battery, described as a solid-state cell, is already in production in Finland and that initial capacity is roughly one gigawatt-hour. The company said the cells will first appear in the Verge TS Pro and that the design grew out of work by Verge Motorcycles engineers dating back to 2018. The article places these claims against past high-profile solid-state promises and notes reasons for cautious interest. Several technical details and patents are reported as forthcoming in the coming months. Key points: - Lehtimaki, Donut Lab's CEO, is reported to have said the cells are in production in Finland with initial capacity around 1 GWh. - Donut Lab provided performance figures including about 400 Wh/kg energy density and claims of full charges in as few as five minutes, with the Verge TS Pro quoted at about a 10-minute charge. - The company and its partners described long cycle-life claims; Donut Lab is quoted as saying 100,000 cycles while Verge cited a more conservative 10,000 cycles. - Donut Lab and a partner executive said the cells are thermally stable down to about -22°F and that designs may not require active liquid cooling. - Lehtimaki would not specify the exact chemistry; the article reports the company describes the chemistry as free of conflict materials and says patents are coming. - The article notes the longstanding technical challenge of dendrites in solid-state designs remains a point where the company has not yet published full details on how it was addressed. Summary: If the reported production and performance claims are verified, the company says the cells would offer higher energy density, faster charging, and reduced cooling needs for vehicle applications, and Donut Lab says it could scale manufacturing to the U.S. in response to demand. Undetermined at this time.
