Solid-state battery race accelerates

[mkhuffman]

A guy on YouTube compared the Donut test results with the Samsung 25R, which is a 10 year old battery. Per his calculations, the 25R is a better battery than the Donut battery because it is more efficient. A 10 year old battery.​

​

Donut is obviously a scam.​

This is the video where you see the charge curve of the Donut cell compared to a standard wet electrolyte lithium-ion cell also including other comparisons which pretty much confirm it's not a Solid State cell..

Great video.

He does say it is an impressive battery and at the limits of what he has seen before:



Sad that their grand claims are just a big nothingburger. It may be a decent battery, but not what they claim it is.

Unsurprised in Virginia.

The Donut Labs battery apparently doubled the range of the Verge motorcycle. I just have a hard time believing the Donut Lab guys would go through the trouble of renting a display at CES to pull a prank. They already have a respectable product in there hub motor. They weren't looking for investors. Their claim does sound to good to be true, no rare elements, 5 minute charge , 100,000 cycles, no thermal runaway concerns and double current density cheaper than lithium ion. I do love how the Chinese proclaimed it was impossible to do because they couldn't do it with their exponentially larger labor force. We should know in the next few months as they start delivering the motorcycles and the competing manufacturers tear them down.
I'm guessing you to make a statement like you did you must know something that you're not willing to share with us.

The will "do" it a week after someone does it.

Donut released part 2 of their series. Per this guy's analysis, it performed better than a lithium battery typically does, but there was evidence of outgassing. Which if it did release gas, indicates it was not a successful test.



So far the testing has shown some unusual (in a good way) results, but also warning flags about their claims. The biggest claims have yet to be proven.

Not so sure it was outgassing as much as melting of the bag sealant

The point is we don't know. Which is concerning.

Some of the ratings are far beyond practical.
I assume running at half the max charge or discharge will be overkill and plenty safe if everything else checks out.
