Unexpected Phenomenon Observed In Lithium-Ion Batteries [self healing!]

Brookhaven National Laboratory scientists have observed an unexpected phenomenon in lithium-ion batteries – the most common type of battery used to power cell phones and electric cars. As a model battery generated electric current, the scientists witnessed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing.

This discovery, published in the journal Science Advances, is a major step toward improving the battery life of consumer electronics.

Esther Takeuchi, a SUNY distinguished professor at Stony Brook University and a chief scientist in the Energy Sciences Directorate at Brookhaven Lab said, “If you have a cell phone, you likely need to charge its battery every day, due to the limited capacity of the battery’s electrodes. The findings in this study could help develop batteries that charge faster and last longer.”

Inside every lithium-ion battery are particles whose atoms are arranged in a lattice – a periodic structure with gaps between the atoms. When a lithium-ion battery supplies electricity, lithium ions flow into empty sites in the atomic lattice.

The conversion reaction sweeps rapidly across the surface before proceeding more slowly in a layer-by-layer fashion through the bulk of the particle. Image Credit: Brookhaven National Lab.

Bttt.

I assume it would be good for electric vehicles too.

Yep!....................

"This diagram shows the spread of positively charged lithium ions across the custom-built FeF2 nanoparticle..."

Ridiculous diagram...Everyone knows that Li ions are green and Fe ions are black...

Looks kind of like a ferrous wheel

Red Badger,
You just posted a lot of good articles about energy storage breakthroughs but you’re leaving out the one that will be the biggest (and soon), imo. EEStor.

They are using transcolored Fe ions................

Great pun!,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Got link?......................

claims to have developed a solid state polymer capacitor for electricity storage.[1] The company claims the device stores more energy than lithium-ion batteries...

Only if graphene is involved... https://en.wikipedia.org/wiki/EEStor

News isn’t out yet. They have a long (>10 year) history of false starts and setbacks, but they’ve survived. Word is that they will reveal shortly. Could be any day. The wikipedia page is pretty good. And this page is by a stockholder.. https://eestorlonginvestors.wordpress.com/technology/ The good news is the technology company is American. It is 70% owned by a Canadian company though. (I own some of the stock.) I’ll send you a PM if they come out with news.

Keep us posted!...................

Quit Li-ion.

Nice pair of articles! I don’t have nerves steely enough to ride that $50-100 trading range of Tesla, but I don’t think it’s going to completely crater this year, still too many koolaid drinkers out there. Fisker Inc is banking on a quick charge for their cars.

Will we soon be able to charge electric cars in just a minute? [Super capacitors?]
