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.
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?
To be fair, it's not much of a negotiation for him.
It's like convincing a salesman to let you take a Ferrari for a test drive. If you're a homeless junkie who hasn't showered in two weeks, you better be one hell of a negotiator. Whereas if you're a millionaire with a nice suit, all you have to do is ask.
I was going to say this isn't really Nobel Prize material, but then I remembered they have a peace prize ...
I removed myself from the jean-pool, and all I got was charged with indecent exposure.
Creating new, non-recycled batteries already requires smelting. And requires almost 2800 degrees Fahrenheit for cobalt.
Maybe stop swimming naked with guys named Jean.
I once jumped into a jean-pool, but i got cought in the zippers. Almost drowned.
with free egress and ingress.
From what I hear, this is not an accurate description of the 405.
No, he's just really, really, really, really short.
Depends on how you generate the heat. What if you used waste heat from something else? Or better yet, a solar furnace - many, many, many sun-tracking mirrors focused on a single spot, 2800 degrees shouldn't be impossible. Just take up a lot of desert...
Miffed because they awarded the peace prize to Kissinger (firebombing) and Obama (drones), or do you think it's bullshit for some other reason?
As long as we are stuck on this planet, everything is in finite supplies.

Like the Nano Doctor on Rick and Morty.
It must have been something you assimilated. . . .
If they got a miniengineer they could do this on a much larger scale.
What is a Fahrenheit?
What if you used waste heat from something else?
280F is waste heat. 2800F is not.
Steelmaking... but then it probably wouldn't be "waste" heat...
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.
TFA is the Los Angeles Times, so doubtless they converted the number to Fahrenheit for their readers. The original paper probably gives it in Celsius, but is paywalled so I can't confirm.
If you can find an international reference news article about a researcher in UC San Diego which retains the number in Celsius, you should submit that as an alternative source article. Otherwise, you must be new here if you're expecting the editors to convert Imperial to Metric in story submissions.
