Production ready solid state battery

Comes from a Finnish company, Donut Lab, sounds really positive, biggest ones are the lack of impact cold weather has on it and charging times.

Yes quite a shock this one, since this is a very small company and it has come out of nowhere. Though perhaps it was really developed with/by a partner.

Massive companies have spent billions trying to develop this technology like QuantumScape.

We will have to see if others can verify the claims.

European as well, I see they have a boy working there who is ex McLaren and Rivian.

They also make ev motors so seems at the forefront of stuff

Yes, that is why it is particularly surprising.

They are an electric motor company, not a battery company, though I think I read they had close relationships with a battery company.

Got a VPN on my phone, so has an add blocker never knew there were any there😁

advertised on the Verge website as 2 sizes available
 
I hope this is true, it would be a big development.

However, there is a problem in working out what 'solid state' means and firms have been found to be making false claims about solid state batteries before...

Is Yoshino REALLY a Solid State Battery? - Undecided with Matt Ferrell

I published a video a while back about a solid state battery that’s available to purchase for yourself today, but very quickly, questions sprang up around its solid state bonafides. A few of you pointed me in the direction of a company that did a breakdown of Yoshino’s battery that showed it...

This is what leads people to a bit of scepticism until the claims have been verified by third parties.

Indeed!

Unless it is just hype and no product which might lead people to distrust the industry going forwards.

How do you have something that is commercially available, but still at the production ready stage?
If you watch the advertorial video, note the EV bike promotion is in the same staged facility the Donut talkfest is produced.

Not one bit of actual testing is show throughout the whole thing, freezing a box claimed to be a solid state cell with no actual charging or discharging occurring, along with the reproduceable and therefore verifiable testing equipment attached showing real life testing and live readings in both current and voltage, the same with baking the box, it's nothing more than a smoke and mirrors show.

The only bit of video showing anything, is a package being charged and a meter showing 4v ..... LTO cells 2 in series x however many required to accept a charge for the time it took to do that video clip, inside that package, would give the same results in the very short piece of video provided.

The EV bikes travelling down the road look like an AI generated piece, shows nothing but hype ..... the Guinness world record, was for riding 350kms around London on a single charge, not exactly highway cruising is it, but all the video accompanying the flash on the certificate shows highway cruising ...... and the video actually says that wasn't using the solid state battery ..... yet the hype certainly suggests it .....

The era of foil cell tabs has passed sometime ago, yet, here they are in this flash new solid state cell/module .....

This is generally referred to as vapourware, a lot of hype designed to get the vulnerable to invest their probably borrowed money, into building their dream machine, only to find none of it actually exists in the real world.

They might have some lab produced specimens, but having actually been tested at the high charge and discharge rates for even thousands of cycles ...... really, where is the independent Quality Assurance testing facility data and verification ..... you'd think that would be something he would mention ......

I like his estimations that it is a 3D printed capacitor. The real difference between a capacitor and a battery is, the thickness of the anode and cathode material coating, the trade off is the amount of energy it can actually store.
Sodium ion uses a "hard" carbon anode (negative plate), with a graphene separator, even if a dendrite built up and pierced the separator, graphene has the unique ability to self repair ..... it's all to do with how the bits cling together to form this nano-sized mesh.

If they have made a large capacitor, added a current/voltage limiter, you would get the flat charge curve, then add a voltage booster to increase the voltage fed into the capacitor, double the voltage, halve the current and 1/4 the resistance, double that again and so on, you end up with a very high voltage capacitor but not a lot of storage, but reverse the process till the output is back to 4v @ 60 amps.
The claimed energy storage of 400wh/kg, so a claim of 100Ah @ 4v storage ..... so 60 amp charge rate is around 0.6C, less than LFP and Na+ (sodium ion) .....

That leads to the possibility that this is an advanced Na+ 3D printed battery using their "secret" solid electrolyte that is part of the tech owned by the company they absorbed.

Cycle life and capacity degradation are yet to be verified ........
I do agree with his analogy, give the money to either invest or gamble ..... with enough insider information, I'd probably back the horses ......
