Finnish technology company Donut Lab has revealed a new generation of batteries known as Donut Lab batteries. The technology could significantly improve the future of electric vehicles.
These batteries rely on solid-state battery technology. Many experts consider this the next major step in EV battery development.
Unlike traditional lithium-ion batteries, Donut Lab batteries use solid materials inside the cells. As a result, they can offer better safety and higher efficiency.
What Are Donut Lab Batteries?
Donut Lab batteries are a new type of solid-state battery designed for electric vehicles. The company introduced the technology during CES 2026 in Las Vegas.
One key advantage is the absence of liquid electrolytes. Instead, the batteries use solid materials inside the cells.
This design reduces the risk of overheating or fire. It also improves overall energy storage efficiency.
In addition, the battery pack can potentially be lighter than current EV batteries.
Charging Speed of Donut Lab Batteries
One of the most exciting promises of Donut Lab batteries is ultra-fast charging. According to the company, the battery could reach a full charge in about five minutes.
That charging time is similar to refueling a gasoline vehicle. Because of this, charging delays could become far less common.
If the technology performs as expected, electric vehicles could become far more convenient to use.
Higher Energy Density and Longer Range
Another advantage of Donut Lab batteries is their high energy density. The company claims the batteries can reach about 400 Wh per kilogram.
This figure is higher than most current lithium-ion batteries. Many existing EV batteries range between 200 and 300 Wh per kilogram.
Higher energy density creates two possible benefits.
First, electric vehicles can achieve longer driving range with the same battery size.
Second, manufacturers could build lighter battery packs while maintaining the same range.
Long Lifespan of Donut Lab Batteries
The company also claims Donut Lab batteries could support up to 100,000 charging cycles.
This number is significantly higher than most batteries used today. As a result, the battery could last much longer without major degradation.
This factor is important for EV owners. It may also reduce long-term vehicle ownership costs.
Where Donut Lab Batteries May Appear First
The first real-world use of Donut Lab batteries may appear in electric motorcycles from Verge Motorcycles.
The companies plan to begin using the technology around 2026.
If the tests succeed, the batteries could later move into electric cars. They might also appear in trucks and other heavy vehicles.
Could Donut Lab Batteries Change EV Technology?
At the moment, Donut Lab batteries still need further real-world testing. Industry experts want to confirm their performance outside the lab.
However, the technology looks extremely promising.
If it succeeds, electric vehicles could charge faster. They could also become lighter and more efficient. Most importantly, they could deliver longer driving ranges.
