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 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(This comic is a bit outdated nowadays, but you get the idea).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.

Oh boy! Idiot TikTok kids is going to start microwaving devices.
didn't 4chan do that once?
Yeah they tricked people into believing that Apple added something that allowed users to charge their phones by microwaving them

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 LLM~~ 4chan came up with the idea
Remember kids, updating to iOS 7 enables your phone to charge wirelessly in the microwave.
The “peer” that reviewed it was another LLM.
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?
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
i was just thinking i could use an excuse for some skin grafts
brb, putting e-bike battery in oven
Sounds like "microwave to charge" for the modern era.
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.
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.

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.
I think you mean they shouldn't write authoritatively about things they don't understand, because what you said is really gate keepy. There's nothing wrong with learning.

brb chucking my batteries in the oven
it's a cheap and easy thrill
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 %.

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

How does heat mitigate the dendrites? Also doesn't extreme heat damage the batteries? They barely hold up under high temperatures as-is.

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?

Neat! So if I put my phone in the microwave it will reset the battery?
