Summary
A startup called Donut Lab claims it has created a "solid-state" battery that could change the world. The company says its battery is made from cheap materials, charges in just a few minutes, and can last for hundreds of years. While these claims sound amazing, many experts in the battery industry believe the technology is not real. As the company tries to prove its critics wrong with new videos and tests, more questions are being asked about whether this is a breakthrough or a clever marketing trick.
Main Impact
If Donut Lab is telling the truth, the impact on the electric vehicle (EV) industry would be massive. Currently, the biggest problems with electric cars are that they take a long time to charge, the batteries are heavy, and they eventually wear out. A battery that charges in five minutes and lasts for a lifetime would make electric cars much more popular than gas-powered cars. It would also reduce the need for rare and expensive minerals that are hard to find. However, if the claims are false, it could hurt the reputation of the entire green energy industry and make investors more afraid to support new technology.
Key Details
What Happened
At the start of 2026, Donut Lab announced it had a finished solid-state battery ready for production. This was a surprise because much larger companies, like CATL in China, do not expect to start making similar batteries until 2027. Donut Lab released videos showing their battery performing well, but they did not share the specific technical data that scientists usually look for. This led to a wave of doubt from experts who called the announcement a scam.
Important Numbers and Facts
The company makes several bold claims about its battery cells. First, they say the battery holds 400Wh per kilogram, which is about twice as much power as the best batteries used today. Second, they claim the battery can be charged and emptied 100,000 times. Most current batteries only last for about 1,000 cycles. Finally, they say the battery can go from zero to 80 percent charge in five minutes. In a recent test using a motorcycle, the battery took 12 minutes to reach that level, which is fast but slower than what was promised.
Background and Context
Most batteries we use today, like the ones in phones and cars, use a liquid or gel to move energy around. This liquid can sometimes catch fire if the battery gets too hot. A solid-state battery replaces that liquid with a solid material. This makes the battery safer, smaller, and able to hold more power. Because of these benefits, every major car and tech company is trying to build one. Donut Lab is a branch of Verge Motorcycles, a company known for making electric bikes with unusual designs. The CEO of Donut Lab, Marko Lehtimäki, has a history of making big promises, including a previous claim about creating an artificial human brain.
Public or Industry Reaction
The reaction from the battery world has been very negative. Leaders at major battery companies have called Donut Lab’s claims "clearly fake" and "a fraud." Many experts point out that the company has not shared the weight or size of the batteries they tested, which makes it impossible to verify their claims. In response, Donut Lab started a website called "I Donut Believe" to release weekly test results. They hired a Finnish research group called VTT to run independent tests. While the tests showed the batteries could work under high heat and fast charging, they also showed the batteries swelling up, which is usually a sign of failure in traditional batteries.
What This Means Going Forward
Verge Motorcycles says it is now shipping its new TS Pro bike, which supposedly uses this new battery technology. If customers receive these bikes and the batteries perform as promised, the skeptics will be proven wrong. However, the company is also spending a lot of time selling expensive merchandise, like $141 hoodies, to fund their videos. They have also started talking about "Generation 2" and "Generation 3" batteries before the first version has even been fully proven. This behavior makes many people think the company is more focused on hype than on real science.
Final Take
In the world of technology, extraordinary claims require extraordinary proof. Donut Lab has provided some interesting test results, but they have also avoided answering basic questions about their battery's weight and design. Until these batteries are in the hands of regular users and tested over a long period, it is best to remain cautious about these "miracle" claims.
Frequently Asked Questions
What is a solid-state battery?
It is a type of battery that uses solid materials instead of liquids to move energy. This makes it safer, lighter, and faster to charge than the batteries we use now.
Why are people skeptical of Donut Lab?
People are doubtful because the company's claims are much higher than what current science allows, and they have not shared enough data to prove their technology works as they say it does.
Can I buy a vehicle with this battery?
Verge Motorcycles claims their new TS Pro Gen 2 motorcycle uses this battery and is ready to ship, but it has not yet been widely tested by independent riders.
