The massive amount of production-oriented research in solid state and semi solid state batteries indicates to me that this stuff is coming soon in a big way. I've been curious about buying an electric car recently, and if I buy one right now it would only be a used one, don't want to fully invest in something about to be obselete.
The founders have sketchy track records. They do a carefully managed social media build-up. There are credible rumors that they’ve been simultaneously raising money by cold-calling moderately wealthy people around the country. (Finland has extremely little oversight for private fundraising; you can basically sell shares in your zero-revenue startup to grandma next door — as long as you’re careful about wording your claims as “projections”.)
So lots of red flags. Everyone would love it to be real of course because it’s been a long since Finland’s tech scene had a global hit like Nokia and Supercell… And perhaps the Donut founders are counting on that mood.

I make the same argument when I buy a computer. If I just wait a little longer, there will be a faster cheaper version of what I can buy today. When buying anything that depreciates, the best strategy is to wait (possibly forever) and only buy when you really need it now.
Earlier quoted context omitted.
Unfortunately that's not the same as VTT. VTT would be more like "National Institute of Scientific Research"
It says its sign by this guy: https://www.vttresearch.com/en/news-and-ideas/petri-soderena... He has an e-mail address and a phone number, I doubt that if the report is falsified it won't come out.
Promising the moon and stars just like with Donut.
Donut Labs also had a video presentation of some kind of automotive design software that also sounded too good to be true.
This guy is a serial scammer.
First report for Donut lab battery is out. Here is the TLDR Specs 26 Ah nominal capacity at 1C discharge rate 94 Wh nominal energy with 3.6V nominal voltage Operates within 2.7V – 4.15V recommended range (max charging to 4.3V) What was verified 5C charging (130A): 0-80% in ~9.5 minutes, 0-100% in ~13.5 minutes 11C charging (286A): 0-80% in ~4.9 minutes, 0-100% in ~7.3 minutes Successfully delivered 98.4-99.6% of char…
Edit: Reading the report, they talk about “charge capacity” (Amp hours in/out) efficiency of 98.4% to 99.6%, but this seems potentially misleading. The actual charge energy efficiency is more like 90%.
> Successfully delivered 98.4-99.6% of charged capacity even after extreme 11C charging
Note the Wh numbers for discharge vs. charge energy.

Apparently the first 3rd party test was on fast charging and the 3rd party is VTT, which is the government affiliated(owned?) "VTT Technical Research Centre of Finland" The people listed on this report appear to be on LinkedIn, so I guess it will be easy to confirm if the test document is authentic. The announcement of the test: https://youtu.be/d2QU_LpkSPs Hopefully, soon we will find out if this seemingly "too good…
Fast charging, long life, low cost – pick two. Actually, there are a bunch of other variables (energy density, stability, discharge current, etc. etc.), so the probability of a technology that improves one significantly without negatively affecting at least one other is vanishingly small. Hence the number of overhyped battery technologies that get reported but never productised.
