https://hackaday.com/2026/04/27/why-solid-state-batteries-short/ supposedly solid state batteries aren't as safe and solid as claimed.
Dendritic growth and mechanical stress is worse due to the inflexible nature, causing these to short out while charging similar to older lithium batteries.

@thoralf
Das war wohl so zu erwarten. Der Schaden, der durch solche PR-Stunts entsteht, ist wahrscheinlich groß - wie es im Text heißt:"they’re intentional statements to delay people’s EV-buying purchases by making them think a breakthrough is just around the corner"
Und trotzdem hoffe ich irgendwie auch selbst immer darauf und bin dann enttäuscht.

A leader at one of #DonutLab’s key partners (#NordicNano) has filed a criminal complaint against the Donut, stating that the company has overstated its offering (I guess relating to their #solidStateBattery. Article behind paywall.

Yep, it’s fast: Donut Lab’s solid-state battery gets its first test result

The first third party test of the #DonutLab (claimed) #solidStateBattery are released. Done by VTT, it confirms that the battery is capable of very fast charging without active cooling.

So far, I haven't read nothing but skepticism about the extraordinary promises of #DonutLab and their new #solidstate #battery.
Even #derStandard (Austria) released an article that summarizes expert opinions on that: https://www.derstandard.at/story/3000000309341/donut-lab-es-mehren-sich-zweifel-am-solid-state-wunderakku-aus-finnland
So it's either a remarkable #scam (more likely according to sources) or an interesting new technology. 🍿

Heard about #DonutLab yet? Me neither.
However, they released an amazing new #DonutMotor 2025 in multiple products and now they're releasing a new kind of #solidstatebattery #DonutBattery that may disrupt the whole market according to their promo video: https://www.youtube.com/watch?v=Y-aPS2AwMbc
- cheaper than #LiIon
- 50% weight or +100% capacity for same weight
- full charge in 5min
- no loss due to temperature
- more cycles than you will ever need
- no degradation over time due to fast #charging
- no problematic materials
- ...You "donut believe"? Well, they want to prove their point soon: https://www.youtube.com/watch?v=uiOma6v_EZY
Now, they have my attention. 🍿

Someone, presumably #DonutLab themselves (the company making big claims about a #solidStateBattery), has just launched this website:

New information related to the #DonutLab #solidStateBattery saga. The #Verge #EV motorbike company, which is closely related to Donut Lab, has finances that are in such a mess that the auditor refused to sign the financial statement. Missing inventory management, sales receipts etc paint a picture of irregular business practises. A statement reads that the company's continuation depends on 'ongoing funding discussions', which currently 'lack commitments'.

Weekly output: FCC frees Verizon from phone-unlocking rule, Donut Lab’s solid-state battery, Wikipedia turns 25, Google traffic trends
This week brought a lot of unpleasant headlines, but none made me feel uneasy like the news that Washington Post reporter Hannah Natanson was subjected to an unexpected visit by the FBI at her house Wednesday that concluded with investigators confiscating her work and personal laptops, her phone and her smartwatch–all seized, it now seems, on a fraudulent pretext. Since then, the man who spent his equivalent of pocket change to buy the Post in 2013 has said nothing about that in public, yet another way in which Jeff Bezos has shown himself an unworthy successor to Katharine Graham and her son Don Graham.
In addition to what you see below, I wrote a post for Patreon readers sharing bonus bits about what I learned at CES two weeks ago.
1/12/2026, FCC Unties Verizon From 60-Day Phone-Unlocking Rule, PCMag
Two days after the Federal Communications Commission granted Verizon’s wish, Verizon suffered an hours-long outage that people could work around relatively easily if their phones were unlocked to allow them to add a third-party eSIM.
1/15/2026: Wikipedia Is Now 25 Years Old [Citation Not Needed], PCMag
I had made a mental note to myself to write an essay about the free online encyclopedia hitting the quarter-century mark, but then the actual date snuck up on me. Fortunately, the lede and the headline basically wrote themselves.
1/17/2026: Donut Labs’ Solid-State Battery-Powered Motorcycle Turned Heads at CES, But Big Questions Remain, PCMag
Writing this left me feeling over my skis more than usual–I don’t cover battery technology in any great depth, this startup has disclosed almost nothing about the design of its solid-state batteries, and two outside analysts weren’t willing to assess their pitch. But reading up at length on this company and on others working on better EV batteries did make me realize one thing: There’s enough innovation happening here that we don’t need Donut’s invention to work.
1/17/2026: AI Is Still Hammering News Sites, Google Search and Social Referrals Plunge, PCMag
The brutal declines in Google search traffic reported in a study published Monday by the University of Oxford’s Reuters Institute for the Study of Journalism caught my eyes and those of my editors, but I also found some news value in this report’s stats about which online platforms and technologies newsroom leaders plan to emphasize or back away from.

Some small details in this Finnish article about #NordicNano and #DonutLabs (and their claimed #solidStateBattery):
Here the Nordic Nano boss seems to be stating that the battery being discussed is not a super capacitor.

Battery Experts Say Donut Lab’s “Miracle” Solid-State Battery Is a SCAM | Electric Viking

En terwijl #Trump oorlogen voert om, naar het schijnt, #olie te bemachtigen (of gewoon om een bully op wereldschaal te kunnen zijn), hebben ze in #Finland de #solidStateBattery uitgevonden. Deze laadt in 5 tot 10 minuten op, maakt gebruik van ruim beschikbare, betaalbare en geopolitiek veilige materialen zonder zeldzame of gevoelige grondstoffen en geeft de auto een actieradius tot 600 kilometer. De productiekosten liggen laag.
Fietsen blijft altijd beter, maar toch.

The #DonutLabs CEO posted on one Facebook conversation to say that third party tests of their #solidStateBattery will be published in a few weeks.
I still can’t make head or tails of this announcement. There is some speculation it’s a capacitor. I mean, more power to them if it is (kind of weird some say that as criticism), but capacitors have had substantially lower energy density.
Also capacity drain energy quite quickly.

A platform of solid state battery tech coming out of stealth in Finland by #donutlabs #finland #suomi #solidstatebattery
Congratulations to the team working on saving our planet. This could transform the world as we know it.

One spec that is curiously different is energy density. In #DonutLabs marketing they state 400Wh/kg. This is a remarkable figure as it would enable battery operated planes. It is significantly better than current batteries. However HBP’s site states their #solidStateBattery at 150Wh/kg. This is in line with current Li-Ion batteries (though their battery has other benefits).

Here is the website of the German company I suspect is the key partner for Donut Labs’ / Verge’s battery. With more information on their #solidStateBattery:

I’ve done some investigation into the big claims by #DonutLabs and their first use of a #solidStateBattery (in the #Verge #EV motorbike). In an old interview on Finnish public broadcaster Yle, #NordicNano (Donut portfolio company) stated to be working with a German ‘innovator’ on a battery. I think I may have found them:
https://apers.ro/2023/10/16/german-engineers-create-battery-10x-longer-life-40c-operation/
All the specs match what Donut is claiming. We don’t yet know what power output it has and how (likely small scale) production will work.

Finnish #DonutLabs is promising the first in-production #solidStateBattery and to be used in the #EV motorcycle #Verge. Claims are that this can be done at a smaller cost, with high energy density, with very rapid charge times, safer and with a longer lifespan (100,000 cycles) than existing batteries.
Very big claims. Revolutionary even. We wait and see.
