The new battery delivers 400 Wh/kg of energy density, enabling longer range, lighter structures, and increased flexibility in vehicle and product design. It can be charged to full in just five minutes without limiting charging to 80 percent, and supports full discharge safely, repeatedly, and reliably.
Donut Lab says the battery experiences minimal capacity fade over its lifetime, with a design life of up to 100,000 cycles, offering practical longevity that far exceeds existing technologies. There are no flammable liquid electrolytes, no thermal runaway, and no dendrite formation, thus eliminating the root causes of battery fires and ensuring safety.
Testing has found that the at –30°C, the battery retains over 99 percent of its capacity, and when heated to temperatures exceeding 100°C, it continues to retain over 99 percent capacity with no signs of ignition or degradation. The 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.
“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” said 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.”
The Donut Battery can be produced in custom sizes, voltages, and geometries, enabling structural integration and non-traditional formats like serving as the body of a drone or a vehicle chassis.
Verge Motorcycles Donut Battery powered bikes will be introduced on to the road in Q1. They can be charged in less than 10 minutes, deliver up to 60 kilometres of combined range per minute of charging with the long-range version delivering 600 kilometres of range on a single charge.
The battery is also being deployed in defence platforms, with current projects in development including a four-wheel tactical buggy and a next-generation drone platform.
