Something about this really stinks...

Electrek’s Take:

We’ve been tracking the Donut Lab story since Verge first announced its solid-state motorcycle at CES, and we’ve maintained that extraordinary claims require extraordinary proof. This first VTT report is a step in the right direction, but only a step with arguably the least impressive metric announced.

I’ve been watching this, I mean proof is proof while the validity may be the question with a Finnish lab completing the testing for a Finnish company.

Like we don’t believe that covid most likely came from wuhan.

Again I want it to be real and I’m sure we are some time away from this being affordable on the scale of a vehicle sized battery, the facts that remain unverified are really important to the continued interest out of the community imo.

I agree with you. The release this week was a start. Very large claims remain unverified. But they have a cell and it takes a charge. Baby step.

More to come. I am eagerly waiting and enjoying the mostly civil conversation around the claims and proof.

I love putting people on ignore when they provide no value. Saves time when catching up on the forum, less posts to read. Just sayin....

Being skeptical is healthy, we should question everything. There's certainly a precedent for major breakthroughs to fizzle out. Nikola's hydrogen trucks and Theranos' magical blood test come immediately to mind. Especially in science, we can't just take anyone's claims at face value. Recall the room temperature superconductor claim?

That said, being skeptical is not the same thing as immediately calling something a scam. The claim of a scam implies evidence of falsehood. Thus far, we have no evidence to disprove the claims. We only have suspicion and are awaiting validation of the claims. I think it would be fair to call it vaporware until it becomes tangible. I think it's fair to doubt that the company will fulfill it's promises. I do not think it's fair to presumptively claim it's a scam.

I'm not overly excited, as I'm tired of reading about SSB claims and always being 10 years away from them being in production. Like many here, I'm not holding my breath, but I am watching.

Can you imagine charging a 100kWh battery at 11C? We have a hard enough time finding chargers at 400kW right now. While I'm not a doubter that we can make the grid work for EV's, that's a huge step up in power required to charge. It seems like the major advantage with this tech would be simply maintaining a higher rate for a longer time. Charging at 2-3C from 10-90% would be massive.

let’s not forget the same guy announced an AI consciousness last year too. It was vaporware.

if you aren’t factoring that into your skepticism here then you’re absolutely doing it wrong.

Certainly puts a lot of fuzziness in trying to install future charging stations. If you can charge in 5 or 10 minutes, except at a Buc-ee’s, no one needs 20 stall Superchargers but you probably will need a Megawatt battery storage unit.

How many times has Elon claimed FSD? Yet Tesla puts out a quality product. So no....the AI claims have negligible bearing in my opinion.

Any PR is good PR?

The guy sounds like an expert to me

 

[Zprime29]

Just watched this last night, haven't had a chance to vet him but I've seen a few other videos and he definitely seems like he at least has a solid background. Several valid points, although I think his final point complaining about cycle life testing I think is a bit over dramatic. I'm not going to ding them for extrapolating lifetime cycles from a degradation curve.

A brief search says 6 months to 1 year for full life cycle testing of standard Li-Ion cells, so I think it's fair to assume similar testing was done with Donut's battery. If at 1 year, the curve was indicating it would take another 3 years to finish the testing, I'd call it day too. We have yet to see the evidence for that, so it is simply an assumption at this point.

The rest of his points, all the similarities to standard Li-Ion characteristics, is quite alarming and disappointing. I'm still watching, but no longer hopeful.

SSB. Sounds like what we used to say about Brazil.
Brazil -dominant economic power of the future. Always was. Always will be.

edit: waiting for godot.

 

[El Duderino]

This is another good video reviewing the lastest Donut video and lab report. This one is more objective. But it still arrives at the conclusion the voltage curve looks like NMC Lithium Ion cell...

Pretty difficult to be objective about this fairly obvious scam at this point -- but good on them.

If this turns out to be all a bluff, the reputational damage alone for such a small company will be difficult to come back from. They have everything to lose and nothing to gain by trolling us on the tech.

Attention, clicks. Note no one seems to care that they did the same thing with an AI intelligence just a year ago that didn't exist either.
