Cue dumbasses tossing their iphones in the toaster oven in 3… 2…
Microwaving the iphone was close to the right answer.
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?
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.
brb, putting e-bike battery in oven
One simple trick to make your ebike fly.
Sounds like “microwave to charge” for the modern era.
How does heat mitigate the dendrites? Also doesn’t extreme heat damage the batteries? They barely hold up under high temperatures as-is.
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.
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 %.
Where’s my blowtorch?
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.
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.
Edit: hmm seems I might be generalizing too much. Not all batteries use water based solutions. My point is that you should avoid a pressure buildup inside the battery due to reaching the solvents’ boiling point.
wha wha what
no, it’s an organic solvent like ethylene carbonate/propylene carbonate + some other stuff, which have a boiling point of 230+°C ( 446°F)
heating up batteries is (mostly) fine (under controlled scenarios with known good batteries, spicy pillows can always happen with bad batches) as long as the plastic holding them together doesn’t melt
you physically CANNOT make a lithium ion battery with water because lithium reacts with water
from the wikipedia page
Lithium reacts vigorously with water to form lithium hydroxide (LiOH) and hydrogen gas. Thus, a non-aqueous electrolyte is typically used, and a sealed container rigidly excludes moisture from the battery pack. The non-aqueous electrolyte is typically a mixture of organic carbonates such as ethylene carbonate and propylene carbonate containing complexes of lithium ions.[45] Ethylene carbonate is essential for making solid electrolyte interphase on the carbon anode,[46] but since it is solid at room temperature, a liquid solvent (such as propylene carbonate or diethyl carbonate) is added.
So you’re saying I SHOULDN’T preheat my toaster oven to 425F???
UH-OH!!!
brb. Gotta put out some fires.
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.
I tried it on my car but it doesn’t turn on anymore. Deceiving news
Sounds like a 4chan prank, but… 🪦
This turns everyone else on, though.
Oh boy! Idiot TikTok kids is going to start microwaving devices.
didn’t 4chan do that once?
4chan did everything once
Not meth
You sure about that?
This is giving me racist dog-whistle vibes.
TIL ADHD is either a “race”, or the diagnosis is “racist.”
Fuck off, troll.
Its actually the “went to church, talented white folk there”, posted by “fren”, somehow they learned random old dude was “88” which has no bearing on the story and isn’t usually something that comes up in short conversations, and the “I was like <common behavior from easily influenced person> before I did these things”
It gives recruitment/fishing vibes to me. If 100 people read it and 99 see ADHD and move on, but 1 person asks them how they could also feel good about themselves, boom, one more Nazi recruit. That’s how dog whistles work. You toss an innocuous thing like “88” in your story, it let’s those in the know that you’re part of the team and you’re on the job.
Who is this “4chan”?
do we even know?
This title is pretty bad, the paper focus is in designing new battery technologies not magically restoring capacity on the batteries we have today.
Is the paper in the article? I couldn’t find it.
Would you be so kind as to link us?
it is this one: https://www.nature.com/articles/s41586-025-08765-x
Oven, 450?
Nah, set it to broil for optimal results /s
Warning: heating earbuds batteries to over 300F also causes fires
Reading this tells me the author has absolutely 0 idea of how physics work and is nothing but a blogger of consumer grade equipment. People like that should refrain from trying to understand how science or scientists work.
Obviously, physics aren’t done in Fahrenheit.
Had to laugh at your comment. Not that it matters in this case, your ear buds are not going to magically combust at just 150°C
They’ll not combust, I’d hazard a guess that air pods are made from ABS which has a glass transition temperature of 105C, so they will melt.
Dimethyl carbonate boils at 90° so the battery could pop
ABS which has a glass transition temperature of 105C, so they will melt.
Well, they’ll deform. ABS won’t melt at 150°C, it’ll just become soft and flexible. But yes, it’s a bad idea for your earbuds.
Thanks, climate change.
