World’s first all-solid-state battery in production vehicles

400 Wh/kg. Full charge in five minutes. Designed for 100,000 cycles.  Lower cost than lithium ion.

Key features designed for  real world deployment

Solid state batteries have been discussed for years, but most remain confined to labs and pilot programs. Donut Lab’s solid state battery was designed for vehicles, real duty cycles, and scalable production, and is available today.

Full charge in less than 10 minutes

Up to 60 km of combined range per minute

Long range version: 600 km on one charge

400 Wh/kg energy density

Donut Battery delivers 400 Wh/kg of energy density. In practice, this enables longer range, lighter structures, and greater freedom in vehicle and product design, delivering performance gains without architectural trade offs.

Full charge in 5 minutes

There is no need to limit charging to 80%. Full charge and full discharge are safe, repeatable, and expected in daily operation, supporting demanding use cases without limiting battery life.

Designed for 100,000 cycles

Unlike lithium ion, Donut Battery is designed to degrade at a significantly slower rate. Minimal capacity fade supports long service life under continuous use and repeated fast charging.

Case study

Proven in real programs. Battery-first.

All-solid-state batteries are often positioned as future technology. That’s no longer the case. Donut Battery is already deployed in real vehicles and active development programs.

Extreme Safety By Design

Donut Battery addresses the primary root causes of battery fires by design.

No flammable liquid electrolytes
No thermal runaway chains
No metallic dendrites that can cause internal shorts

Safety is not added later. It is built into the chemistry, structure, and system behavior from the start.

Cold performance test

Validated for operation in extreme cold environments.

Tested at sub-zero temperatures, demonstrating stable output and minimal capacity loss under cold operating conditions. At −30 °C, Donut Battery retains over 99% of its capacity.

Metal fins or panels are shown in the background, with the text "-30°C" prominently displayed in large white letters, suggesting extremely cold temperatures.

High-temperature test

Validated under sustained high-temperature operation.

Tested above 80 °C, maintaining stable operation without ignition or performance degradation. Even when heating the cell beyond 100 °C, capacity retention remains at over 99%, with no signs of ignition or degradation.

Built on abundant, geopolitically safe materials

Donut Battery is designed to scale globally without  supply chain bottlenecks, cost volatility, or  geopolitical dependency.

100% green and abundant materials with global availability
No reliance on rare or geopolitically sensitive resources
Lower material cost than lithium-ion
