Oh boy! Idiot TikTok kids is going to start microwaving devices.
didn’t 4chan do that once?
multiple times the big one was to wrap a spoon in duct tape and microwave it or boil bleach and drip alcohol in it to make crystals.
4chan did everything once
Not meth
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
so putting batteries in the fridge wasn’t useful after all, we should put them in the oven
so I can now put my spicy pillows in the oven and tell the insurance men the internet told me to?
Yes but how can shareholders profit from this??
By making battery renewing devices.

By not switching to Na based batteries and keeping a lid on Li mining.
Even BYD is betting on Na tho.
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
Important note near the end of the article - they aren’t saying we should cook batteries really -
“The team’s hypothesis is that the structural disorder developing inside LIBs may become a “tunable parameter” that, if tweaked using chargers at precise voltages to alter said battery composition, could be used to rejuvenate the batteries in our tech without fires.”
This is a good old idea that goes back to the days of desulfating lead batteries with powerful shocks of high-amperage current. Might just need a special Healing Charger that applies the right voltage/current to dissolve the bad crystals in lithium-ion systems
I remember recovering dead 18650 cells from laptop batteries and “restoring” them with a 12V modded PC PSU. Quite a few of them actually started working again and had some capacity for a few tens of additional cycles. Those cells were never left unattended in a charger and they were always only used in a device you could chuck in a moment’s notice.
10/10 do not recommend.
Oh God I can already see all the questionable “Restorer Chargers” and the like from Temu that will be more likely to burn down the house…
With electric cars you might not even need a special charger so much as a special charging cycle. Its already the norm for cars to tell the charger what voltage and current they want, and its already the norm for cars to carefully control their battery’s temperature during charging.
That’s not to say you’d necessarily be able to do this with just a software update, but its not too far off from the current paradigm.
Yeah that’s a good point. Ours uses the same refrigerant system as the AC to cool the battery, and the actual “charger” for the battery is inside the car being controlled by its software etc. The cables that plug in on the outside are technically just power wires, with the charging brains inside the car. That would be amazing if they could update the software to rejuvenate the battery once a year or something.
Neat! So if I put my phone in the microwave it will reset the battery?
Only if you want it soggy, air fryer works better
So is a toaster the new wireless charging hub?
this feels like bait
In reality, this doesn’t affect the existing batteries we have, it’s just for future battery technology.
Is this before or after they reach the spicy pillow stage?
I think before, but there’s a trick for spicy pillow just poke a vent hole, trust me I was in IT for 6 years ;p
i was just thinking i could use an excuse for some skin grafts
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
Otherwise this reads as if
some LLM4chan came up with the ideaRemember kids, updating to iOS 7 enables your phone to charge wirelessly in the microwave.
The “peer” that reviewed it was another LLM.
Well if it was a human it wouldn’t be a peer, would it
Connection reset by peer.
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.
80 degrees what?
See, this is where the problems begin.
heat to 80K…oh wait
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.
Edit: hmm seems I’m saying nonsense. The solvent may be able to handle higher temperatures.
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.
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.
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?
I was gonna say there’s no typo but the comment has been edited. What was it originally? Que?
Yup, que
¿Que dumbasses?
brb, putting e-bike battery in oven
One simple trick to make your ebike fly.

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.
It might be less the quality of the research and more this:
(This comic is a bit outdated nowadays, but you get the idea).
Except the headlines say “scientists report discovery of miraculous new battery technology using A!”.
Also i think people don’t realize how long it takes to commercialize battery technology. I think they put them in the same mental category as computers and other electronics, where a company announces something and then its out that same year. The first lithium ion batteries were made in a lab in the 1970s. A person in 2000 could have said “I’ve been hearing about lithium ion batteries for decades now and they’ve never amounted to anything”, and they would be right, but its not because its a bunk technology or the researchers were quacks.
Hmm, you’re right. At a guess, this field might represent the maximal combined interest of both scientific and pedestrian readership within technology research, since on the one hand energy density and storage logistics is the key limitation for a ton of desirable applications, and on the other most consumers’ experience with batteries establish them as a major convenience factor in their day-to-day.
Edit: you’re*
