Donut Lab, a Finnish company, has unveiled a production-ready solid-state battery that delivers 595 km of driving range with just 10 minutes of charging. Set to power Verge Motorcycles’ 2026 models, this battery features 400 Wh/kg energy density, extreme temperature resilience, and a 100,000-cycle lifespan, marking a significant leap in EV energy storage technology.
How Does Donut Lab’s Solid-State Battery Achieve Fast Charging?
The Donut Battery supports DC fast charging at up to 200 kW, allowing it to gain 60 km of range per minute. By replacing liquid electrolytes with solid materials, the battery avoids flammable components, thermal runaway, and metallic dendrites that can cause internal short circuits. This design enables rapid, safe energy replenishment without compromising performance or longevity.
What Are the Advantages of Solid-State Batteries for EVs?
Solid-state batteries offer several key benefits over conventional lithium-ion cells:
High Energy Density: At 400 Wh/kg, the battery stores more than twice the energy per kilogram than typical EV batteries.
Extreme Temperature Performance: Tested from -30°C to 100°C, it maintains over 99% of its range in these conditions.
Long Lifespan: Designed for 100,000 charging cycles, far exceeding lithium-ion’s typical 1,000–5,000 cycles.
Sustainable Materials: Uses abundant, green materials, reducing reliance on rare or geopolitically sensitive resources.
These features collectively improve driving range, charging convenience, safety, and environmental sustainability.
| Feature | Conventional Li-ion | Donut Lab Solid-State |
|---|---|---|
| Energy Density (Wh/kg) | 180–200 | 400 |
| Charging Time for 60 km | ~6–10 minutes | 1 minute |
| Thermal Safety | Moderate | Excellent |
| Cycle Life | 1,000–5,000 | 100,000 |
| Material Sustainability | Limited | High |
Which Vehicles Will Use Donut Lab Batteries First?
The first production units are scheduled for Verge Motorcycles in 2026, with pricing starting at £31,980 in the UK. Donut Lab has announced over 200 OEM partnerships, though additional deployment plans remain undisclosed. This initial adoption will likely pave the way for broader integration into electric motorcycles and potentially other EV segments.
How Do Solid-State Batteries Compare to Current EV Batteries?
Compared with lithium-ion and LiFePO₄ cells, solid-state batteries excel in energy density, safety, cold- and heat-resilience, and lifespan. Their solid electrolytes eliminate flammable liquids and metallic dendrites, drastically reducing risks while supporting high-rate charging and stable power output. These features make SSBs particularly suitable for high-performance motorcycles, long-range EVs, and extreme climate operations.
