Sounds too good to be true. Seriously, if the CEO had any proof, he wouldn't need to hang out on CES. He would be showered with billions of $$$ and investors would fly in from all over the world. Instead he is selling motor cycles? Hard to believe. Why not have at least two different top universities having tested them?At least some insights into their production to verify the claims? And the motorcycle has a 33kWh battery for 600km? At what speed, 40kph?
Good luck to them anyway...
Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density

Re: Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density
#162I don’t understand, why would this debut only in a motorcycle? Wouldn’t there be a much bigger market and investor interest in putting it in a car initially?
It can be many things, like large car companies staying away from unproven tech or them demanding production capacities too large to gamble with brand new tech.
This niche motorcycle brand has already established business relationships with Donut Lab, they were using Donut Lab's electric motors. Probably the Donut people easily worked out a release pipeline together in a bar or something, which would have taken years with VW.

#163> Donut Lab’s all-solid-state battery delivers 400 Wh/kg of energy density This is damn impressive. I suppose all the makers of military drones are lining up at the factory already. I mean, electric bikes are fine, but who has the most burning need to increase range and payload?..
This could arguably be a huge contribution by EU to Ukrainian war aid, given the batteries are manufactured in Finland.

Um... Did nobody see the Verge motorbike which is now shipping as standard with this battery? And the three companies which are also deploying the new battery tech? If this is a scam, it's definitely a very very sophisticated one.
I don't know about a scam, but the EV skateboard they're using has been available for other companies to use for a few years, while the other two companies share the same leadership as Donut/Verge and appear to be founded within the last few months. The battery may be great, but the multiple company launch seems a bit of a marketing gimmick.
not too sure of your point. The skateboard has been available with conventional lithium ion batteries. What they're saying here is they've just upgraded it to the new solid state ones. Fairly logical.And I'm totally mystified by the shared leadership comment. What shared leadership?

#165I'm very skeptical of any company that just 'pops up' and makes a bunch of claims that will shake up the industry. I doubt they'd sell to endusers, but not having any partnerships with established brands with sales figures is a big red flag. No mention of manufacturing capabilities either so I think it's just hype (or worse a rug pull for early investors)

One thing that most people have missed is that in the Verge small print they discuss the range of the motorbike as being 217 miles for around town driving, which plummets to 127 at 56 mph per hour on the highway. That seems quite a big drop to me, but there again I'm not a battery expert.

Agreed. But you can supposedly book a test ride on a Verge motorcycle with this battery.[1] Verge has three stores in California, two of which are in Silicon Valley. Base price $35,000 with the good battery. Solid state batteries have been working for a while now, but they're still far too expensive. Mercedes has one demo car. Ducati has one demo motorcycle. Maybe they just decided to accept the high cost and sell a…
I'm not sure the test rides are for the version of the bike with this battery. The bike already exists with a more conventional battery pack.
I've had a brief test ride on a pre-production version of the Verge TS. All seemed OK but I thought the handling seemed weird - maybe due to the rear tyre size and geometry.

It depends; not all drones are kamikaze-type. Great many drones are used for delivery (food, ammo, medkits), for reconnaissance, as carriers of smaller drones, and as radio retransmitters. Bomber drones also fly a large number of sorties before getting shot down or breaking down from wear. Ground teams usually have a bunch of batteries for quick replacement, because charging is slow. With these fast-charging batterie…
I've looked at the stats, and it's: - 45 flights per recon consumer quadcopter drone before it's lost - 69 flights per heavy bomber drone before it's lost They switch the batteries before each flight anyway, so even batteries that are rated for 10 cycles would be good enough if the price/performance is good enough. Certainly batteries rated for 300 cycles are an overkill. Source (from March 2025): https://www.forbes.…
It's less about cycles and more about the energy density per kg. Nothing on the market comes close to 400Wh/kg.

#168If this is true, it's possible that the technology is from Nordic Nano. That would at least explain how a motor/software company could pull a battery out of thin air: https://www.donutlab.com/nordic-nano-investment/ Their chief scientist is working on solar-powered hydrogen production, which seems fairly unrelated to solid state batteries: https://www.nordicnano.co/chief-scientist-bela-bhuskute-will...

Yes, it is from Nordic Nano. It is nanoprinted and trivially scalable. Free of lithium, cadmium, lead, and cobalt. Uses abundant raw materials free from geopolitical constraints. https://yle.fi/a/74-20118784 Factory in Finland, started around Q3/2025. https://yle.fi/a/74-20180376 Verge Motorcycles bike with the new battery at CES, apparently at West Hall 5658.

Nanoprinted snakeoil - infinitely scalable. Good enough to grab 3M€ public grants and some more from gullible private investors.
Honestly, if they had the tiniest proof of their claims (400Wh/kg, 5min 0-100%, operating temp -30°C to 100°C, no Li/Co/Mn and somebody looking at the production and taking the output to the test) they would be absolutely drowned in money to the point that sama would become jealous.

That is only a picture of a factory building. They are 100% greenwash grant grabbers with no real substance. There are plenty of these people in Europe. The motorcycle is likely in China designed and produced.
If grant grabbing is what you'd consider a fulfilling life, then come to Europe - it will be an El Dorado for you.

#169This is so out there, checks every box imaginable or they’ve done some incredible copy writing. So then, elephant in the room, where is the catch? It’s it the cost? They haven’t left much else - - made from geopolitically abundant resources - unlikely to catch fire - fully charges in 5 mins - does not lose capacity over cycles - retains 99% capacity at -30C and 100C What is today, April 1st??
> [Is] it the cost?
The press release also claims:
"and demonstrates a lower cost than lithium-ion."
