As a scientist this is how you science. Independent verification is the bedrock of science.

The numbers and data speaks for itself.

This kind of breakthrough is not just about EVs the modern world simply doesn't exist without the energy density of the lithium ion battery. It's in everything smartphones, tablets, laptops, medical devices, anything that's portable that requires an electric current simply put modern society doesn't exist without the energy density of lithium type cells. These solid state cells have the same density or more, but can charge in a fraction of the amount of time even if never adopted at the EV level these will fundamentally change consumer devices.

What's equally impressive is the lack of the need for active cooking even at a record 11C rate and no high pressure structural bindings that liquid filled cells need.

Cells like these are the next generation of cells for the trillion dollar consumer battery market. Smartphones that charge in 4 min or under , same for laptops or tablets. Drones, EV scooters and Ebikes too.

The 21st century is gonna be lit y'all.

but it takes what ? a hundred times the power that the slow chargers do ?

When does Donut Lab go public?

I really like it when science is done well.

Not to hijack the thread, but it’s my opinion that topics like Climate Change and also Evolution are simply not approached like other scientific areas. Observable? Repeatable? Testable? Falsifiable? I figure people can believe whatever they want to believe. If it’s an article of religious faith that mankind is changing the climate or that all life sprang up randomly from nothing, then it’s not my place to attack that faith. But those particular bits of “science” cannot ever be handled the way Donut Lab just got verification from VTT.

Kudos to Donut Lab and to VTT.

Not equal to LFP or Li-Ion double.

“The Finnish startup claims 400 Wh/kg energy density, under 10-minute charging”

LFP is 160wh/kg
LI NMC is 220wh/kg

I hope the IPO soon.

Why do they not give the time for 100% charge? Does the last 20% take far longer time? Always question why they report in this manner, because there is a reason that they report it as they do.

I saw a video yesterday that indicated the whole thing is a boondoggle.

The guy was going over VTT's results, and he said there was a lot of troubling things in there, and it looked like Donut Labs was misleading people.

He said the battery looked like a lithium battery based on it's power curve, power density, and other data.

And there was no proof presented that it was actually solid state.

And burn out the battery after 5 charges?

What did the temperature of the battery hit while charging at such high rates? Would that severely lessen the life of the battery? Increase chance of fire?

Can someone explain something to me? I thought when a battery “discharges” that means it gives up its electrical energy. So how do these battery maintain 80-90 percent of their energy after “discharge?” Please enlighten me if I read it incorrectly.

I’ll wait until they know what the life of that battery is before getting excited.

Are the SS batteries a fire hazard like the lithium ion batteries?

What size was the battery and capacity? i mean was it a AA cell? An EV size battery? Not enough info unless i skiopped a paragraph....I’ll try tio look it over again.

This is what my wife needs for her cell phone. She is always running her battery down, constantly recharging it.

Interesting but I will wait till these hit the commercial market and whether or not they meet expectations before praising.

Also, if these things aren’t made to be economically recycled it’s just more e-waste heading to the landfills.

Does it go flat as fast as it charges?

Sounds promising but knowing the actual temperature rise is essential and not stated.

How quick long does it last on a cold night with the heat on driving back mountain rodes?

EVs suck. I’ll take a high horsepower V-8 with a great cam and headers any day. Loud and proud.

Is this Samsungs Silver battery? They are very careful not to mention Silver battery as Silver is in a mining deficit, and the U.S. Crimex is close to defaulting on Silver deliveries.
