Donut Lab has unveiled what it claims to be the world’s first commercially production-ready all-solid-state battery, signaling a potential shift in electric vehicle (EV) energy storage.
The Finnish startup, known for its in-wheel electric motors for Verge Motorcycles, says the new battery is now available at gigawatt-hour scale for global OEMs, with Verge’s updated TS Pro motorcycle set to become the first production EV powered by the technology in the first quarter of 2026.
The company asserts that the all-solid-state design delivers multiple advantages over conventional lithium-ion batteries, including higher energy density, faster charging, improved safety, extended lifespan, and wider operating temperature tolerance. According to Donut Lab, the battery reaches 400 watt-hours per kilogram and can be fully charged in as little as five minutes for up to 100,000 cycles without limiting the state of charge to 80 percent—a significant improvement over traditional Li-ion cells, which typically offer 250–300 Wh/kg and last for around 5,000 cycles with restricted charging.
Extreme temperature performance is another claimed benefit. Donut Lab reports that its solid-state cells retain more than 99 percent of capacity at temperatures ranging from -22°F (-30°C) to 212°F (100°C), addressing a key limitation of liquid electrolyte batteries. Safety is also emphasized, with the cells designed to prevent thermal runaway or ignition if damaged. The startup also notes that the battery’s materials are widely available and “100 percent green,” reducing dependence on scarce or geopolitically sensitive resources while lowering manufacturing costs compared with conventional Li-ion batteries.
In practical terms, Verge’s TS Pro motorcycle demonstrates the technology’s capabilities. The standard model maintains a city range of 217 miles, consistent with its previous lithium-ion-equipped version, but a larger battery option boosts range to 370 miles while cutting charging time from nearly 35 minutes to under 10 minutes. Verge intentionally extended the nominal charging duration to give riders a short break, illustrating real-world usability considerations alongside technical performance.
Donut Lab CEO Marko Lehtimäki highlighted the significance of the launch, noting that solid-state batteries have long been delayed despite industry anticipation. The introduction of Donut Lab’s all-solid-state battery could address persistent limitations in EV energy storage, including charging speed, thermal stability, and long-term degradation, potentially accelerating adoption across motorcycles, passenger vehicles, and heavier applications such as commercial trucks and construction equipment.
