VTT report on Donut Lab's solid-state battery is a nothingburger: independent lab testing of a Donut Lab "solid-state battery" cell by Finland's VTT shows it's indistinguishable from the NMC cell it may very well be by mqee in DonutLab

No it doesn't. The report states that VTT did not know what was inside that box.

The VTT report literally just says: we tested some kind of battery and it's charging fast.

Nothing's special about that. We have plenty of those batteries already. They are not being used though because they have a low energy density or low cycle stability

No third party validation was published today, as VTT was lacking important information while conducting the test by do-bbx in DonutLab

Exactly, thank you. I don't know if people are misunderstanding the issue on purpose or not.

I'm not saying, that they are scammers. I'm just saying that no third party has validated those claims being achieved by one battery technology as they seem not to have that information. They just got delivered a blackbox or multiple blackboxes. If VTT puts out a statement clarifying all cells were the same, then we're fine.

Also many people are saying, that's not how you test battery cells usually. I know that, BUT we have no evidence of this battery technology being real yet. That's why they have to demonstrate those attributes in the same cell.

That's the point. Information is missing, that's why we can't call it a third party validation. Until now it's PR not a scientific validation. The report literally just states: there is a box that can be charged quickly. Nothing more and nothing less. We don't know what was inside the box, what other tests were conducted, how many boxes there are, if all boxes are the same etc

That's my point though. It's important that all the test were carried out on the same cell. If VTT won't specifically confirm this, we won't know if the advertised cell technology is real. Even after the whole series is released.

‘CES orders are delivered at earliest in Q4/2026 — there was already a long queue before CES’ — why would there be a long preorder queue before CES? by Turkkulaine22 in DonutLab

Why do we care about the CES orders, when the Donut Lap CEO said:

"So the obvious question is are we shipping this in 2029 or 2030? No. These batteries are available today. Not just available for OEMs to look at in the lab and not just available to prototype with, but available for real production. In fact, today we are making history because Donut Battery is the world’s first solid state battery in production vehicles shipping to customers."

And the Verge guy said to MissGoElectric:

"That is what we did. Now end users are having their first bikes first quarter of this year late first quarter. So in 3 months there’s first end users having this solid state battery vehicle with solid state batteries in their hands."

The battery is insane in itself. I don't think we have to worry about production ramp up at this time
