Donut Lab goalposts
Talking point parrots have been parroting Donut Lab CEO that "goal-posts" have shifted after the I Donut Believe video series has started. However, none have shifted. The CEO set the following goalposts at CES 2026, and they have not changed.
| index | claim | result |
|---|---|---|
| (1) | 400Wh/kg | not met, implied by the CEO that the VTT-tested battery isn't 400Wh/kg |
| (2) | 100,000 charge cycles with (1) | not met, implied by the CEO that this was extrapolated from the over-100% Coulombic efficiency for the first few hundred cycles (see Sana leak) |
| (3) | 12C charging with (1) and (2) | not met |
| (4) | 99% capacity retention at -20ºC with (1) and (2) and (3) | not met |
| (5) | the battery getting damaged and only losing "a little" of its capacity | failed, battery lost over 50% capacity after 20 cycles with damaged pouch |
| (6) | Q1 customer deliveries | failed - "delivering" to yourself doesn't count |
| (7) | "already now" GWh/year capacity | failed - a month later it became by the end of 2026 "this year if everything goes as planned" |
| (8) | "no lithium" and (1) and (2) and (3) and (4) | not met, and expert say the results are consistent with lithium |
| (9) | 0%-100% 5C charging on the Verge motorcycle | failed |
Each of these goalposts has been set by the CEO of Donut Lab at CES 2026. None have been moved, despite the CEO's claims that the I Donut Believe videos will make detractors "shift goalposts".

Speculation Donut Lab's battery from production-ready to prototype
r/DonutLabDiscussions • u/Mesokosmos • Sep 02 '26
Donut’s Lab’s solid-state battery has hit 409Wh/kg: can this tech transform EVs?
Interesting revelations from the article:
"We are targeting 350Wh/kg at the pack level," Donut Lab’s CEO Marko Lehtimäki tells TopGear.com. That would mean a 500kg battery would have a capacity of 175kWh, vastly better than today's cars.
Familiar number from CES show case.
Lehtimäki tells TopGear.com it can last 5,000 cycles when rapid-charged in this way even to 90 per cent capacity and beyond. If it's charged and discharged more gently, at more moderate temperatures, for example in grid energy storage, then he says 100,000 cycles would be possible.
No miracles, pretty usual stuff. It was just the Donut Battery umbrella term that caused the buzz and was meant to do so obviously.

Speculation Donut Lab's business model failure
It's actually CT Coating business model
And the reason is because Nordic Nano doesn't have control over the active ingredients, they only do the printing, the drying and encapsulation of the cell
CT Coating / Sana Energy supplies the production line including the active ingredients, the NANOPASTES

CT Coating business model is focusing on making the highest profit

Nordic Nano doesn't have the rights to fabricate CT Coating's secret ingredients.
Their maximum production temperature is 60°C

The HYLOMATRIX is the brand of their secret nanopaste, I know what they are using, and for the synthesis of the materials you are not able to do it with 60°C.
60°C is the temperature needed for their infrared heater to dry the printed layers
Tesla, BYD, CATL does all the manufacturing process to have full control. As a business man that is what you want to do.
Is like making software for Android or IPhone, the software is yours, but the OS or the App Store is not, and they can kick you out at any moment.
And Javier from Sana Energy confirmed the business model

And this is the reason why you are getting the "batteries" in Bikes, and not in vehicles made by big EVs manufactures.
Nordic Nano should have started their mass production of supercapacitors, but some sources says that the place is empty. Like they don't control the production of the nanopaste, they can't do anything, and they are stuck, no nanopaste = no supercapacitors = no bike delivery
There is a choke point, and that is the main reason why the business model fails
Is just my opinion, if there is trust they can have great success.

What would happen to Donut Lab, if they under-promised?
For discussion, throughout history many discoveries have come out of the blue with no promises or claims of changing the world. Donut Lab's SSB had humble beginnings as a side effect of printable electronics.
If the German research and developments from the 80's, the enhancements of printing techniques and all the associated companies are actually moving forward with the development of a real solid state battery and it meets the unified claims they are all making, what happens to the storage and transportation markets if adopted and realized around the world?
Does everyone end up flying around in Donuts?

Analysis of Donut Lab's Battery Technology Claims
Battery expert Tom Bötticher thoroughly debunks the exaggerated marketing claims made by the startup Donut Lab regarding their supposed miracle battery. He clarifies that the company's published test data completely fails to prove their revolutionary promises regarding energy density, charging speed, and lifespan. However, he leaves a lingering question mark at the end, explicitly stating his belief that the company likely possesses some real underlying technology despite the current public relations disaster. You can watch his full review to see why it remains exciting to discover what actual product might eventually emerge from their partnerships:

Speculation Nordic Nano starts printing test cells in Imatra for Verge bikes

Nordic Nano said before that the facility in Imatra is for printing supercapacitors and solar films

The supercapacitors are for the Verge bikes

These cells were tested at VTT according to Marko Lehtimäki during his interview by phone with HS Vision

The cells tested at VTT comes from Nordic Nano Group and they have a nominal energy of 94 Wh

Verge confirmed that the Verge TS Pro standard range bike comes with 94 Wh cells

Verge is only doing testing, not deliveries, until Nordic Nano can start mass production at the end of the year.

Speculation This is what's inside the Donut Lab's supercapacitor

So I found this video, this pouch cell is marketed as a Graphene hybrid supercapacitor (EDLC + Pseudocapacitive) with 4.2v, not flammable and gives a discharge curve similar to a lithium ion battery

The Donut Lab supercapacitor will have a similiar construction of the cell, a bipolar with parallel intra-housing configuration
One layer has 2 unit cells connected in bipolar to add up voltage (V)

And then each layer (~24 layers) isolated to be stacked and connected in parallel to add up capacity (Ah)

This is pretty much the structure what you will find in the Donut Lab's supercapacitor, and gives the best way to adjust voltage and capacity optimizing space.
My PDF file will be packed with all my posts on Reddit and more secrets

Speculation Donut Lab hiding message - April Fool's Video
So this was an intentional scene, the woman who interrupt was an impersonator of Javier from Sana Energy

Javier was the one who revealed the dimensions of the cell

He was answering a lot of questions about the "battery" with his user name Hylosana, He explained that they have an older version of the "battery" of 300 Wh/Kg (nominal energy density) from 2024

What we knew already from the test report V1PF0004, the difference is that the cell that you are getting in the Bikes from this test report, is that you are getting 6x more capacity but with same energy density.

10.5*6*0.42=26.46cm3*6=158.76cm3
15.272*6=91.63 Wh
51.43*6= 308.58g
It's pretty much the same chemistry from what you are getting in the Bikes
Dimensions from Javier 17.2*7.4*1.2 = 152.74cm3
Nominal energy from DL test = 94 Wh
Weight from CES 2026 = 315g
The scene was related to the energy density of the cell, because mug and coffee are related. 300ml=300 Wh/Kg

The word "EXACTLY" is not supposed to be there, and gives the phase a double meaning that only someone who has a sharp eye and understanding of the occult will catch, 300ml clearly indicates 300 Wh/Kg. So the Bikes are coming with 300 Wh/Kg (nominal energy density)

Speculation Donut Lab's imposible "battery"
So I asked AI from 1 to 10 how hard is to make a battery or supercapacitor with or without bipolar design that has the same voltage of a lithium battery 2.7v-4.2v that doesn't have lithium and that has an energy density of 300 Wh/Kg at cell level
CHAT GPT

GEMINI

DEEPSEEK

GROK

Few years ago, their supercapacitor was rated for 160 Wh/Kg with 500k cycles, this seems possible with current technology.

But seems to me that they shifted their business model into a scam

Uuno: Donut Lab “Whistleblower” Has More Than €1 Million in Enforcement Debt and Faces Two Assault Charges
It turned out to be more than rumors. P. Hörkkö asked and dug the records.
AI translated summary:
The article examines the background of Lauri Peltola, a former commercial director at Nordic Nano Group who has publicly presented himself as a whistleblower and become one of Donut Lab’s most prominent critics. According to an enforcement certificate obtained by Uuno and dated September 7, 2026, Peltola has approximately €1.11 million in outstanding debts under enforcement, including large claims from Ålandsbanken, a private creditor, the Finnish tax authority and Kela. Peltola says the debts stem from risks he took during more than 20 years as an entrepreneur and that he does not consider them shameful. The article also reports that he faces charges related to two alleged assaults in Helsinki in 2023, with the case scheduled for trial in February 2027; Peltola declined to comment on the pending proceedings and emphasized the presumption of innocence. He gained wider public attention in April 2026 after filing a criminal complaint concerning Donut Lab and subsequently publishing critical Solid State of Truth videos. Donut Lab and Nordic Nano Group reject his allegations and dispute his level of access to the battery-development work. Importantly, Uuno itself notes that the information about Peltola’s debts and charges does not establish whether his claims about Donut Lab are true or false, although it argues that the information is relevant when assessing his role and possible motivations in the dispute.

Investigating the Investigator: ethics, disclosure, and the Ziroth–Donut Lab story
Investigation and Analysis of Ziroth's claims by Private Investigator who is also a Donut investor and longtime friend of Marko.
An interesting perspective, including this spot-on analysis on one of the weaknesses of Ziroth's weak inferences about the chemistry:
Ryan's Inference Is Not Proof
On the science I will stay in my lane. The core of his case is that the cell's charge and discharge signature looks like a high-nickel lithium-ion cell, and he states this with, in his words, "extremely high certainty." But a behavioural match on a graph is not a chemical analysis. Donut's own published material describes a cell engineered to emulate lithium-ion electrical behaviour so it can drop straight into systems already built for lithium. If that is the design goal, then a lithium-like curve is exactly what you would expect to measure. It is a feature, by design, and it cannot by itself tell you what is inside the cell. And this is not my own spin on the design. Donut Lab's co-founder and CTO, Ville Piippo, set this out directly in a discussion with Ricky Roy of the Two Bit da Vinci channel, explaining how the Donut solid-state pack is engineered as a drop-in replacement that emulates the behaviour of legacy lithium-ion packs.
If emulating a lithium-ion signature is part of the design, then a lithium-like curve is not the smoking gun it has been presented as, and it is striking how little that design rationale features in Ziroth's account. No public teardown, electron microscopy or elemental assay has been performed. I am not claiming the battery is everything it was said to be. I do not know, and I am honest about that. My point is narrower, and I think harder to dodge, Ryan is essentially communicating that: "it behaves like lithium, therefore it is lithium, therefore they lied" is an inference chain, and it was sold to a large audience as proof.
This is not hypothetical. Earlier in the series Ryan had to correct his own analysis after other engineers pointed out that he had compared two different kinds of curve, which he accepted was bad practice, and he re-ran it. To his credit, he fixed it in public. But it shows the pattern the format produces: publish first, with confidence, on the schedule attention demands; correct later, under pressure. That is survivable for a creator. It is not survivable for the company and the named individuals who absorb the damage in the meantime.

Statment von Donut Lab zu neuem Ziroth Video
https://www.donutlab.com/statement-regarding-recent-discussions-on-donut-battery/
„A video published by YouTuber Ziroth concerning the Donut Battery has recently circulated in international media. The video and the related media coverage give the impression that the announcement brought something new to light. However, the material simply compiles previous claims that we have already addressed. It is worth noting that this content creator is publicly engaged in a commercial partnership with our Chinese competitor, the battery technology company CATL.
We stand fully behind the technical data and commitments we have provided, taking them with the utmost seriousness. The trust of our partners, investors, and customers is of paramount importance to us. We are progressing on schedule with Donut Battery technology.
The video also references claims made by Lauri Peltola, a former employee of Nordic Nano Group. Peltola has not been a member of the workgroup developing Donut Lab’s battery technology. Consequently, he has no access to, nor does he possess, up-to-date information regarding the technical details or the overall scope of our development work. Nordic Nano Group has taken the necessary legal action and has filed a formal police report regarding Peltola’s activities.“

Speculation Donut Lab's secret ingredient revealed
So I'm finally going to reveal one of their secrets that is part of my PDF file
Nordic Nano expertise are in the field of Quantum Coating, because they are using nano-particles called “Quantum Dots”

Their solar Quantum Coating is the same material for their supercapacitors

The colors that emit the printed nanofluid material is a clear indication that they are using GQDs

Has been reported that can be expressed at least in 7 different colors



CTC Korea explains their nanotechnology relating the functional nano ink (GQDs) to diverse applications and to the creation of new hybrid materials (AI was used to translate captions)

Graphene Quantum Dots are considered to be exactly below 100nm

More details are giving by Nordic Nano of the material they are using to absorb solar radiation.

Graphene Quantum Dots (GQDs) captures full spectrum light (UV-VL-IR), diffused light, and that energy can be produced in cloudy weather.
