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 as if 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. Anything above 100 is asking for trouble.
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?
Well the electrolyte solution is water based so exceeding the boiling point will cause pressure buildup inside.
Good point. It’s highly concentrated inside a battery if not saturated. Hmm. I still wouldn’t expose them to such high temperatures.
Perhaps a longer duration at lower temperature is safer. I might try it some day with some waste batteries and a battery tester.
Wait, nobody came up with this before?
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 %.
brb, putting e-bike battery in oven
One simple trick to make your ebike fly.

Sounds like “microwave to charge” for the modern era.
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 continues to stay nearly dead? And an application in products would be hard to accomplish. At that temperature, all the plastic etc is going to melt. Maybe the solder as well.
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.
Cue 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?
¿Que dumbasses?
Where’s my blowtorch?
How does heat mitigate the dendrites? Also doesn’t extreme heat damage the batteries? They barely hold up under high temperatures as-is.
I think it has to do with whether or not the battery has a current going through it while hot. I imagine heat probably makes the lithium more soluable in the electrolyte liquid, then the disolved material migrates with the current flow. Heating it without a current flow might allow it to redissolve and at least distribute it more evenly so it doesn’t make one long spike that shorts the battery.
Reminds me of the old days of putting my LG G4 in the freezer
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.
Why’d you put it in the freezer if it wasn’t bootlooping? Just like cold phones?
Well it was my 4th LG G4. Four times a charm I guess.
Thanks, climate change.
Oven, 450?
Nah, set it to broil for optimal results /s
