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.

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.

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 person whose signature is on it, is listed on VTTs website with the same title.

Considering the amount of publicity this thing gets, VTT or the person will publicly refute it pretty soon if it's a fake.

Earlier quoted context omitted.

The PDF is digitally signed with a cert from the Finnish „Digital and Population Data Services Agency“

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.

I think it is safe to assume, given the buzz all around the donut battery, that VTT would immediately release a statement if this report was fake.

Careful though, this test explicitly only tests the charge and discharge capabilities of the battery, not whether it's a solid state battery or not. According to ChatGPT, these results would in theory also be possible with a normal Li-ion battery. I am really hoping this is real though! And waiting for further tests.

Well there's this press release they would publish a report: https://www.vttresearch.com/en/news-and-ideas/donut-lab-comm... with as author the same name on the digital signature "Petri Söderena" for Organisation "Teknologian tutkimuskeskus VTT" and the chain is attested by "DVV Organisational Certificates - G4E" which is on the EU/EEA trusted list: https://eidas.ec.europa.eu/efda/trust-services/browse/eidas/... (by name and key signature). Looks like a legit VTT document to me.

Also, VTT had publicly confirmed earlier that they had conducted tests for Donut Lab.

I'm confident the document and tests are real, but other shenanigans are still possible (and likely IMO).

why?

Because that's not independent verification that the device tested actually _is_ a solid state battery. Just that whatever was tested had certain charging characteristics.

Tbh the exciting part isn’t so much the composition but whether it can actually meet the claimed performance. It could be made of wet gym socks for all I care if it can do 100k charge cycles at 90degC with comparable energy density and specific power to LiFePO.
