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?
Thanks, climate change.
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.
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 %.
We did the opposite, put it in the freezer
brb chucking my batteries in the oven
it’s a cheap and easy thrill
Where’s my blowtorch?

Sounds like “microwave to charge” for the modern era.
Wait, nobody came up with this before?
Oven, 450?
Nah, set it to broil for optimal results /s
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.
Well if it was a human it wouldn’t be a peer, would it
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.
Is this before or after they reach the spicy pillow stage?
The trick is to let them apply this heat themselves.
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
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.
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.
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.
All true, but I am going to be that nerd and point out that there were indeed commercial devices with lithium ion battery packs in them in the mid to late '90s, especially so in the late '90s. By 2000-2001 you couldn’t escape the damn things in cameras, disc players, PDAs, etc. So yes, it did take relatively forever for the technology to become commercially ubiquitous, but not that long. (And yes, the first couple of waves of Li-Ion batteries were indeed crap, and had all of us geeks clamoring for gadgets that still took AA’s for a while.)
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.
