Nanoengineer Finds New Way To Recycle Lithium-Ion Batteries (latimes.com)
Zheng Chen, a 31-year-old nanoengineer at UC San Diego, says he has developed a way to recycle used cathodes from spent lithium-ion batteries and restore them to a like-new condition. The cathodes in some lithium-ion batteries are made of metal oxides that contain cobalt, a metal found in finite supplies and concentrated in one of the world's more precarious countries. Los Angeles Times reports how it works: The process takes degraded particles from the cathodes found in a used lithium-ion battery. The particles are then pressurized in a hot alkaline solution that contains lithium salt. Later, the particles go through a short heat-treating process called annealing, in which temperatures reach more than 1,400 degrees Fahrenheit. After cooling, Chen's team takes the regenerated particles and makes new cathodes. They then test the cathodes in batteries made in the lab. The new cathodes have been able to maintain the same charging time, storage capacity and battery lifetime as the originals did. Details of the recycling method were recently published in the research journal Green Chemistry, submitted by Chen and two colleagues.
A chemistry is performed so that a chemical reaction occurs and generates a signal from the chemical interaction with the sample, which is translated into a result, which is then reviewed by certified laboratory personnel.
His Wife Has To Pull Her Head Out Now! Fucking a bunny when she was having his baby! TRUMP!
This should make EV's more price-competitive! take out your tesla battery after 300,000 km for a refresh and your car is as good as new!
Yes, I'm left. You have a problem with that?
Come on, can't you find decent sources?
Please don't keep this person waiting for their due. (fingers crossed this really is true!)
Re-using Particles is a thing now?
Please remove yourself and your relatives from the jean-pool.
Wow. It's early and we've already got today's battery story out of the way on Slashdot. If only we could get the global warming story out of the way early on then we might have some interesting possibilities open for the rest of the day.
Do he have a big bushy Muslim-style beard and thick black glasses?
TRUMP!
As long as we are stuck on this planet, everything is in finite supplies.

If they got a miniengineer they could do this on a much larger scale.
What is a Fahrenheit?
So many Chinese lies, so little science.
like, reeeaaaaallllllyyy smalll
The real news in this story is that they've apparently shrunk an engineer down to the scale of a few dozen angstrom units. How did they do that? There must be a huge number of applications for such a compact engineer.
Oh but it is!!!! Brawndo's got electrolytes!
There's no shortage of cobalt, nor is it concentrated in one precarious country.
Cobalt is abundant and commonly occurs with nickel and copper. Most nickel and copper mines don't bother with extracting it because the price hasn't justified it yet. As soon as prices look like they're going to stay at an elevated level, you bet your ass that the big miners will add the extraction facilities to their existing monster mines.
