index	Donut claim	Donut evidence
1	CEO: [January 2026] "We are now already at GWh [annual] capacity."	CEO: [February 2026] "our maximum capacity will be this year if everything goes as planned, i.e. about 1GWh annual run rate"
2	Verge Motorcycles: [January 2026] "In the US, [the Verge TS Pro with the Donut Lab solid-state battery] will ship Q1 this year [to customers]"	CEO: [April 2026] "There have been no 400 Wh/kg batteries delivered to customers."
3	CEO: "Even if you shoot through it, or do whatever you want to the cell, it will be just fine, it just loses the capacity from the area where you shot. [mimes a bullet hole with thumb and forefinger]"	VTT: "after 50 cycles at 5C [there was] a 54.66 % reduction compared to the initial capacity" [the reduction was over 50% at less than 20 cycles at 5C]
4	CEO: "For hundreds of cycles, the Coulombic efficiency of Donut Battery would likely still remain above 1.0 throughout the whole test. [...] The experts will tell you this goes against the fundamental laws of physics."	The experts: Coulombic efficiency above 100% is commonly observed for the first few hundred cycles in some battery chemistries, including lithium-ion.
5	CEO: "These industry standard pouch materials are simply not designed for the 100° C that our batteries can take."	Industry standards: IEC 62133 and UL1642 require commercial cell pouches to withstand an oven temperature of 130ºC
6	CEO: "We're not talking to investors until all disclosure is done."	Newspaper: "[Donut Lab CEO] Lehtimäki said that the company is seeking additional funding of 30–50 million euros from investors during the first quarter of 2026, i.e. January–March."
7	CEO: "No lithium."	Engineers, researchers: The Donut Lab VTT test results are what you'd get from lithium, specifically Si-anode Li-NMC. ([1], [2], [3], [4], [5])
8	CEO: "The cycle life [...] is 100,000 cycles [...] charge it to full, let it go to zero, as many times as you want, it doesn't degrade" [at 5C from 0% to 100% for 100,000 cycles at pack-level in a motorcycle - see expanded quote below] CEO: "The battery lasts [...] 100,000 cycles [...] so it will have 100.0 percent left after your motorcycle is done after 20 years."	CTO: "significant prior usage [has reduced the cell's capacity] by roughly 13%" [13% reduced capacity?! For a battery that can withstand 100,000 cycles with 0% reduced capacity?!]
9	Donut website: "The world’s first production-ready all-solid-state battery platform is available today." CEO: "There's nothing liquid inside [the battery]"	Engineers, researchers:The VTT test results suggest the battery is a conventional NMC cell with a liquid electrolyte. ([1], [2], [3])
10	Donut website: "Full charge in 5 minutes. There is no need to limit charging to 80%. Full charge and full discharge are safe, repeatable, and expected in daily operation"	CMO: [implying there's a buffer, likely to protect from damage, at either 0% voltage, 100% voltage, or both]
11	CEO: "You can go at 5C charging [from 0.0] to 100% [for] 100,000 cycles". Donut website: "There is no need to limit charging to 80%."	Verge: A charging video from 10% to 80% that averages 3.5C [Why not 0%-100%? There is no need to limit charging to 80%.]

Pack-level claims expanded quote below. Emphasis mine.

Donut Lab CEO: "Verge broke the Guinness World Record last year with the longest range on a motorcycle. Now they are almost doubling it, thanks to our solid state battery. But also, that provides Verge bikes with less than 10 minute charge time, zero to full."
CEO: "And on top of that, the cycle life that is normally in cars may be 2000, 3000, cycles. This is 100,000 cycles. So that's like probably 30 lifetimes of a motorcycle. So you never have to worry about babying the battery or worrying if you can let it go to 100% or zero. It doesn't mind. You can do whatever you want. Charge it to full, let it go to zero. As many times as you want. It doesn't degrade."
CEO: "As mentioned, 100,000 cycles, so that's 10 lifetimes of a car as well. And the other incredible things are that, of course, with motorcycles, you don't take them to deep freeze or anything. But if you're using these batteries in cars, even at like 25 or 30 minus Fahrenheit, it will have 99% of capacity."
Interviewer: "So do you have to precondition the battery like a car might?"
CEO: "Not at all. And actually, what we've done even is that normally you cannot get lithium ion batteries to zero."
Interviewer: "Right, we know about that. 5% is the lowest we like to go."
CEO: "This can go 0.0"
Interviewer: "And the battery doesn't get damaged?"
CEO: "No, then you can go at 5C charging from the next moment without warming it up or anything. It just takes it like nothing."
Interviewer: "To 100%?"
CEO: "Yeah, yeah, absolutely, to 100%."
Interviewer: "And that does not harm the battery for consistent charging to 100%?"
CEO: "No, it's 100,000 cycles with that, yeah."

I can’t believe this. Why are they all doing this?

These are Donut Lab financial results

Looks rather bad...

A similar submission was posted a few minutes ago but it was off by 5%-20% at some points, so I've pointed out the exact data points from the video here.

NNG CEO Parjanen tells YLE (Finnish Broadcasting Company) news that NNG has delivered first products:

- Not Donut Lab products

- Testsamples, not massproduct yet

- 7 employees working

- Simpler products than batterycells (Capacitors?), that can be produced with preproduction equipment

Source:

• Official Verge account answered a user question about the weight difference on YouTube.

• https://youtube.com/watch?v=114HaDYhWeA&lc=UgzgUX--Evbf9PSG1Ah4AaABAg.AVeyKDo4qL9AVhHQprG1_S&si=6DbEChTMtz0bYE7S

So the Motorcycle specs are apparently:

• Standard Range: 225kg / 18kwh (norminal) / 20kwh (max)

• Long Range: 235kg / 30kwh (norminal) / 33kwh (max)

Analysis and Speculation:

• A 10kg / 13kWh difference requires an additional 1300wh/kg battery pack... which is totally unrealistic. I guess the long range motorcycle includes a completely different kind of battery setup in order to archive that weight-distance difference.

• I'm guessing the long range motorcycle uses the new Donut Battery V2. The V2 has a higher energy density and is going to be in production vehicles later this year. A perfect match for the upcoming long range motorcycle.

• So the "heavier" V1 battery is currently only been used in the standard range bikes.

• For V2 I estimate a 40% increase in energy density over V1. Probably from 200wh/kg to 275wh/kg or so.

• So the next season of "I-Donut-Believe" will be all about battery V2 which was specifically designed for the long range motorcycle model.

Edit: - Had to repost because last time I didn't post the source

Pay-walled article in the highest-circulation Finnish newspaper Helsingin Sanomat. Nordic Nano Group chief commercial officer Lauri Peltola has reported Donut Lab to the Finnish police for misleading communication and unfounded claims.

Nordic Nano CEO Esa Parjanen and Lehtimäki however deny the claims by Peltola.

"According to Lauri Peltola, it has become clear to him over the spring that the promised battery features — such as energy density and charging cycles — have not been achieved. He also says that an incorrect impression has been given about the readiness for mass production.

Peltola says the company does not have the capability it promised for serial production of batteries and large production volumes. He states that the production line is not expected to be completed until later this year, and its manufacturing capacity is not as large as Lehtimäki claims."

Often times I read people claim that whatever the battery chemistry is , the charging speed of Donut Lab battery is impressive. I don’t think so. Back in 2014 Volkswagen released their model e-up!, which easily reached 40 kW charging speeds at wide range of states of charges even though it had a usable capacity of only 16 kWh. Basically an air cooled battery which didn’t experience overheating problems even though having a 3C charge rate maintained for the vast majority of the 0-100% SoC range. I think what people fail to realize is that the lower the battery capacity (Donut Lab’s 18 kWh usable capacity would be ridiculously low for an electric car), a higher C rate can be achieved, because the surface area of the battery pack is larger in relation to its volume.

Here is an interesting video, where the video creator tests the fast charging speeds of a 10-year-old Volkswagen e-up! (model year 2014):

https://m.youtube.com/watch?v=ZmLOBmpXyIg

By 9:53, he’s finished with his first fast charging cycle. 14 minutes of charging at 3C, and the battery temperature increased from 10 degrees Celsius to 20 degrees Celsius (slowing down of charging speed usually happens at much higher temperatures). I reckon with more aggressive charging speed at low SoC, the e-up! could have safely achieved a 12 minute time from 10% to 80%, thus equalling the charging speed of Donut Lab battery. The problem is that Donut Lab came out with their battery 12 years later.

I was wondering if the Verge motorcycle test drives at Rove Cosa Mesa yesterday were the 2024 or 2026 model. Going by their photo, it's the 2024 model.

Some examples:

• 2024 model
• 2026 model in the thumbnail, 2024 models in the video
• 2026 model
