The Finnish 'Donut' That’s Giving the Battery World Indigestion
There's a storm coming from Finland, and for once, it's not just a depressing cold front full of snow and seasonal affective disorder. Since the Consumer Electronics Show in Las Vegas wrapped up, the entire automotive world has been jabbering on about a solid-state battery from a company called Donut Lab. Yes, Donut. I suppose "Reindeer Powertrain" was taken.
I'm guilty of the chatter as well. I wrote about the new Verge motorcycle due in the next few months, largely because it's powered by this magic battery and looks like something Tron would ride if he had a better budget. I had my reservations - as I always do when someone promises me the moon on a stick - but since I am mostly optimistic, I hope there's more to this story than just sugary marketing glaze.
The world, however, is up in arms. Large Chinese companies are not mincing their words, calling it a scam and suggesting Donut Lab is nothing but a fraud. It's a proper bar fight, and I've got a front-row seat. Here is the claim that has everyone spitting out their coffee. A small startup from Helsinki, a place usually reserved for heavy metal bands and rallying drivers, claims to have beaten Toyota, Samsung, and the entire industrial might of China to the solid-state finish line.
The numbers they are throwing around are bonkers: Energy Density: 400 Wh/kg - that's nearly double what you get in a Tesla. Charging in five minutes - not enough time to scratch your nose, let alone drink a coffee. 100,000 cycles before it gives up the ghost - your current EV battery conks out after about 1,500 to 3,000 cycles. This thing would outlive you, your children, and possibly the concept of personal transport itself. Apparently, the new battery works happily from -22°F to 212°F, and it costs roughly the same as current batteries.
If that's true, it's not a breakthrough. It's a miracle. It's like discovering that Guinness is actually a health drink. But the experts have questions, and I don't blame them. Usually, when something sounds too good to be true, it is. But the keyword here is "usually."
Because the plot thickens when you look at where this wizardry is coming from. Donut Lab points toward work done by another Finnish outfit, Nordic Nano. Last October, Donut dropped a "significant strategic investment" in Nordic Nano, which specializes in nanotechnology for solar and battery applications. Nordic Nano then released a report claiming they developed a "bipolar electrostatic capacitor" with specs that look suspiciously like Donut's battery claims. Same 400 Wh/kg density, same immortal lifespan, same fireproof safety.

Boy oh boy. Forget the whole Greenland shenanigans - THIS is the important stuff here. I mean, why would Verge fake the battery? The lie will eventually unravel, and it will take the company down with it. Same goes for Donut Lab. The good news is it's only a matter of weeks, not years, before experts start tearing down the battery pack to see if the solid-state technology is real or just a box of hamster wheels.
