The world of electric mobility has just experienced an earthquake. During the latest CES trade show in Las Vegas, a small Finnish company called Donut Lab dropped a bombshell: a solid-state battery with capabilities that seem straight out of a science fiction movie.
As expected, the announcement quickly sparked controversy. In the competitive battery sector, overpromising is usually synonymous with skepticism, and some even dared to use the forbidden word: scam.
Why all the fuss? Basically, because Donut Lab claims that its cells can charge to 80% in just 5 minutes and withstand up to 100,000 charge cycles. To give you an idea, this would render current lithium batteries obsolete in an instant.
It's understandable that a young startup, appearing seemingly out of nowhere with figures surpassing giants like Toyota or Samsung, would raise doubts. However, the company's CEO hasn't been idle. He recently presented tests conducted by external experts (such as the VTT center in Finland) to certify that his cells are real and deliver on their promises.
Seeing these units in operation is a giant leap. Having institutions outside the company give their seal of approval is a very positive sign. But, as experts, we must remain grounded: a prototype is not a production car.
Manufacturing a few cells under controlled conditions is commendable, but mass-producing millions of units is a whole different ballgame. The automotive world is extremely demanding. A battery must perform equally well in the cold of Lapland as in the heat of Seville, and do so for decades.
Moving from the laboratory to the assembly lines requires a colossal investment and flawless logistics. We still need to see how these components age under real-world use and whether manufacturing costs will make them affordable.
Hopefully, Donut Lab will overcome these challenges. Having our own technology in Europe would give us significant energy independence. For now, we must be patient: the commercial journey is just beginning, and it will be a few years before we see these batteries in dealerships.
We wish this Finnish team all the best. If they deliver on their promises, they will help change the future of transportation.
