Donut Lab has unveiled a solid-state battery, set to go into production with Verge Motorcycles in Q1, 2026, reportedly ready to scale to series production volumes.
“While the advantages are obvious, the future of solid-state batteries has been a moving target constantly delayed when companies working in electrification are asked about when they will become a reality,” commented Donut Lab CEO Marko Lehtimäki. “At Donut Lab, our answer on solid-state batteries being ready for use in OEM production vehicles is now – today – not later. Donut Lab has engineered a new high-performance solid-state Donut Battery that can be scaled to major production volumes and seen now in real-world use in the Verge Motorcycles bikes out on the road in Q1.”
Donut Lab asserts that its all-solid-state battery delivers 400Wh/kg of energy density, can be charged to full in just five minutes without limiting charging to 80%, and supports full discharge – safely, repeatedly and reliably.
Unlike conventional lithium-ion batteries, the Donut Battery is reported to experience minimal capacity fade over its lifetime, with a design life of up to 100,000 cycles, offering practical longevity that far exceeds existing technologies. Safety is built in at the core: no flammable liquid electrolytes, no thermal runaway chains and no dendrite formation. This eliminates the root causes of battery fires, making the Donut Battery extremely safe and truly revolutionary.
Performance has been rigorously tested across extreme conditions. At -30°C, the battery retains over 99% of its capacity, and when heated to temperatures exceeding 100°C, it continues to retain over 99% capacity with no signs of ignition or degradation.
Notably, Donut Lab states that its solid-state battery is made entirely from abundant, affordable and geopolitically safe materials, does not rely on rare or sensitive elements and demonstrates a lower cost than lithium-ion.
