Finland becomes the first country to announce solid state batteries. The Finnish company Donut Lab announced in early January 2026 that it has started industrial production of a solid-state battery already integrated on commercial vehicles.
If the data presented by Donut Lab is confirmed in the real world, we are talking about one of the biggest technological leaps in the field of electric mobility.
From prototype to production line
Donut Lab is not a new name in the field of electrical engineering. The company is known for its hollow-center donut electric motors used on Verge electric motorcycles. In 2025, the company attracted global attention after presenting an electric motor of approximately 860 hp with a mass of only 40 kg.
Against this backdrop, the company claims to have succeeded in industrializing a solid-state battery, a goal the industry has been pursuing for over a decade. Unlike experimental solutions in laboratories, the Donut Lab battery is already available to order and used in production vehicles.
Specifications that exceed current standards
According to the data communicated by the company, the new battery reaches an energy density of approximately 400 Wh/kg, a level significantly above the average of current lithium-ion batteries. Practically, a 100 kWh battery would weigh around 250 kg, with a direct effect on the autonomy and efficiency of electric vehicles.
Another key element is the charging speed: 0–90% in about 5 minutes, the first 75% in about 250 seconds and the rest up to 90% in another 100 seconds. These values clearly exceed the capabilities of current fast charging systems.
The most ambitious claim concerns lifetime. Donut Lab talks about up to 100,000 charge cycles, nearly 20 times more than top-of-the-line lithium-ion batteries. Even in a conservative scenario, this would mean a lifetime that far exceeds the normal cycle of a vehicle.
The battery would operate stably in a temperature range of -30° to +100° degrees, retaining about 99% of performance, significantly reducing the need for complex thermal management systems and the risk of fires or thermal runaway.
The new battery is already integrated on the Verge TS Pro electric motorcycle, delivered from January 2026 exclusively with this technology. The manufacturer indicates a range of up to 600 km for the extended version and a total charging time of less than 10 minutes.
The same solution is also used in electric truck trailers developed by Cova Power, and Donut Lab says the battery is also available to other manufacturers interested in industrial partnerships.
