Great sleuthing he did! I agree with him…Donut Lab is using their partner Nordic Nano’s low-temp solid-state printing process to create a high energy density cap.

Again, a claim, and a prototype, not a production vehicle.

As yet there have been no production versions of the Donut battery delivered either !
forcast is for Q1 2026. ?
And none at CES 26, not even pre-production units ?… despite the big announcement.
“IF” as seems likely , they are using the NN technology and facilities, that production is not due to even start up until “1H 2026” ( first half of 2026 ?).
And it would be optomistic to expect commercial quality from first production runs ….( ask Tesla)

The whole discussion is about this new, as of yet unproven product, being better than what is currently available. All you're saying is it's claims aren't as good as other claims of unproven products. I'm really not getting your point. We should find out relatively soon if Donut meets their claims, and if so and it's a shipping product it will in fact be better than what is shipping in EV's today.

I guess we just have to wait and see what comes out of these claims .

Probably a higher specific energy cathode and better general packaging, although another possibility is much lower first cycle losses by better anode engineering.

Interesting work out of Korea that matches the specs of Donut's claims:

Looking through the study in that article I'm confused by different numbers in this section:
At a current density of 1 A g−1, high specific capacitance of 623 F g−1 (59 F g−1 based on fiber's mass) was obtained by calculation of GCD profile. Based on the high electrochemical properties of PgC10 fiber, the volumetric energy density and power density were calculated as 820 mW h cm−3 (418 W h kg−1) at 23,010 mW cm−3 (11,740 W kg−1) and 192 mW h cm−3 (98 W h kg−1) at 1,150,480 mW cm−3 (587,000 W kg−1) from GCD profile (Fig. 4d). These high energy density and power density results are outstanding compared to other supercapacitor devices [29–32,56,57]. The volumetric energy density and power density based on fiber's mass/volume can be calculated as 77 mW h cm−3 (39 W h kg−1) at 2160 mW cm−3 (1100 W kg−1) and 18 mW h cm−3 (9 W h kg−1) at 108,030 mW cm−3 (55,120 W kg−1).

Ricky interviews the CTO and tries to get more details, adds a bit more color to what they are doing. Interview starts around the 20 minute mark.
Yeah. This guy makes Musk sound like an understating introvert. Either this is huge, as in geopolitics changing huge, or they are brass monkey balled con artists.
I think this is him in 2013.

Marko Lehtimäki is a Finnish serial entrepreneur and tech strategist with over 20 years of experience in digital transformation and electric mobility.
Professional Career
AppGyver (2011–2021): He was the Co-Founder and CEO of AppGyver, a pioneer in "no-code" software development tools. The company was acquired by SAP in February 2021, where the technology became SAP Build Apps.
Verge Motorcycles: Following the acquisition, he joined Verge Motorcycles as CTO and later Chairman. He was instrumental in developing the Verge TS, an electric motorcycle featuring a distinctive hubless rear-wheel motor.
Donut Lab (2024–Present): He currently serves as the CEO and Co-Founder of Donut Lab, which spun out of the technology developed at Verge. The company focuses on "opening the IP" of their in-wheel motors and solid-state batteries to other EV manufacturers.
Kasey Group: Since 2007, he has been the CEO of this group, which develops mission-critical software for the automotive and aviation industries.
Background and Education
Early Interests: Lehtimäki began coding during his youth in Seinäjoki, Finland. He co-founded his first company with his brother, Tuomo, while waiting to re-enter university; they initially built ERP systems and imported scooter parts.
Education: He studied Computer Science at the University of Helsinki from 2004 to 2007.
Memberships: He is an official member of the Forbes Technology Council, a position he has held since 2015.
Role at Asilab
Leadership: He has served as Chairman since mid-2023, steering the company’s mission to develop "synthetic intelligence".
Asinoid Project: Lehtimäki is the public face for Asinoid, a proprietary AI model that Asilab claims functions similarly to the human brain with features like permanent memory and neuroplasticity.
Vision: He has described Asinoid as a "synthetic life-form" and compared current Large Language Models (LLMs) to transistors while positioning Asilab's technology as the "first real computer" of AI.

Well , even if they are using NN tech, it would appear that NN may be suspicous too !
a Finnish local has posted that as of today, the NN site in Imatra refered to is just an abandoned empty building !
” "Investment in Imatra was boosted by the 2,9 million euros in funding received as a JTF development grant. The total amount of investment support is approximately 3,6 million euros."
NN has only 2 two investors , JTF and Donut.
€3.6m doesnt represent a significant business ?

It seems undenyable that they are using NN technology.

In the video I was interested in the SA124 model in the 21700 format. Do we have any information about it? Next to it is the SA112 model, which is 6500mAh @ 22.5Wh, which I should be able to test soon.

It’s a true energy cell, designed for low current use only at about 6.5A or lower. Even at that level you will see very little of its extra capacity unless discharging below about 3V. You really need to be down near 2A-3A to get most of that extra capacity.

I curse you for making me watch an E. Viking video, I avoid him like the plague since he's the one usually claiming a "battery breakthrough" in almost every video. At least he's showing some skepticism for once.

The main reason I boycott all of these kinds of channels is that they deliberately don't include ANY of their sources.

Every Electric Viking video lists its sources.

He does the minimum, and sometimes, many of the things he shows or talks about in their videos doesn't have anything to do with the singular source.
BatteryMooch

He certainly has listed more than one source for some videos and no one lists all the sources for all the things they bring up. I understand what you were getting at, and I have a lot of issues with Electric Viking’s content (and many others), but we can’t say that no one lists any of their sources.
What we think should be listed (or discussed) is a huge new topic all its own.
