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?
Yeah they tricked people into believing that Apple added something that allowed users to charge their phones by microwaving them
It's "Delete system 32" and "magnetize to wipe your hard drive" all over again.
Who is this "4chan"?
do we even know?
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.

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.
People shouldn't compare things to gatekeeping unless they can build a cast iron gate
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.
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.
Dimethyl carbonate boils at 90° so the battery could pop
Good news everybody!
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?
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?

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
Well, there is some data/rumours out there, stemming from a Dutch Tesla forum, that suggests that some fast charging might be beneficial for battery longevity. This seems to corroborate that. I can't remember the case for always fast charging, though.
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.
How did that process work? Did you just connect the +/- ends of the cell to the +/- 12v wires of the PSU and let it feed from the high-amp outputs? Imagine there's plenty of amps on the GPU and CPU power wires
Yup, just plugged it in there. The internal resistance of these cells was high enough that it limited the current somewhere between 3-8A. And this was done only briefly as these cells got quite...warm.

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.

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