Applying 'extreme heat' to lithium-ion batteries reportedly restores their capacity, and I think it's the sustainable tech breakthrough of 2025

  Is this before or after they reach the spicy pillow stage?

    The trick is to let them apply this heat themselves.

  brb chucking my batteries in the oven

  it’s a cheap and easy thrill

  I hope this article is well peer-reviewed. Otherwise this reads like some LLM came up with the idea

    The “peer” that reviewed it was another LLM.

  Sounds like a horrible idea if not carefully controlled. Perhaps up to 80 degrees in an oil bath could redissolve some of the electrolytes. I guess it could work.

    So you’re saying I SHOULDN’T preheat my toaster oven to 425F???

    UH-OH!!!

    brb. Gotta put out some fires.

    How is the boiling point of water relevant to something that’s made of plastic and metal?

    • Rolive@discuss.tchncs.de ⁨3⁩ ⁨hours⁩ ago

      Well the electrolyte solution is water based so exceeding the boiling point will cause pressure buildup inside.

  Que dumbasses tossing their iphones in the toaster oven in 3… 2…

    Microwaving the iphone was close to the right answer.

      What, you didn’t know you had to crank the power to high before microwaving your phone? Rookie mistake

    I love the typo because it covers so many things at once

    Queue as in they’re lining up to do it; cue, as in that’s their cue to be stupid; and que (spanish for what) as in what the fuck are they thinking?

  Sure. But we need to see pics, or it didn't happen.

  The abstract doesn't mention them re-gaining their old capacity. It only says they shrink. And something about voltage. So I have my doubts. I mean it's nice if my spicy pillow shrinks a bit. But what does that help if it's still nearly dead? And an application in products would be hard to accomplish. At that temperature, all the plastics and the solder are going to melt.

    Yes. If you aren’t reading any battery tech article with a huge amount of skepticism you are doing it wrong. More than any other tech sector I can think of, battery research is just absolutely plagued with low quality research that consistently gets picked up by media outlets.

  In the good ol’ days when I ran out of battery and every charger had a different stupid little connector, I often put my phone on the window still or heater to get a little bit of juice to do what I needed to do.

  I guess I am a scientist.

    We did the opposite, put it in the freezer

    Wow, this brought back memories of me rubbing my hands against my old Nokia battery in middle school to heat it up and get a couple extra %.

  Wait, nobody came up with this before?

  Reminds me of the old days of putting my LG G4 in the freezer

  source

  • Rolive@discuss.tchncs.de ⁨4⁩ ⁨hours⁩ ago

    For me that was not so long ago. I still used an LG G4 as permanent car navigation until a year ago or so. I’m still surprised that one didn’t end up bootlooping.

    source

    • Ulrich@feddit.org ⁨4⁩ ⁨hours⁩ ago

      Why’d you put it in the freezer if it wasn’t bootlooping? Just like cold phones?

  Oven, 450?

    Nah, set it to broil for optimal results /s

  Thanks, climate change.
