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.
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.
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.
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.
Hmm, your 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.
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.
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.
brb, putting e-bike battery in oven
One simple trick to make your ebike fly.
turn you into ghost rider.
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.
We did the opposite, put it in the freezer
IIRC freezing accelerates the chemical degradation of lithium ion (especially if you attempt to charge the battery at the same time) and tends to lower both the voltage and amperage of most battery chemistries, but it seems plausible that this might
- temporarily defeat a cell protection circuit, allowing a charging procedure to initialize, or
- delay a thermal failsafe cut-off of a damaged cell long enough to boot or charge a device
Regardless, for those tuning in at home, best to keep your batteries out of the freezer, especially lithium types, unless spicy pillows are what you’re after.
Oh, sorry, since we were talking about the good ol’ days I thought it was implicit I wasn’t talking about lithium batteries
Ah! Yeah it’s been a while but I seem to recall seeing alkaline batteries in a some freezers or refrigerators sometimes when I was a kid, along with other curiosities like rolls of film. No one ever explained why.
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 %.
Oven, 450?
Nah, set it to broil for optimal results /s
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.
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.
80 degrees what?
See, this is where the problems begin.
heat to 80K…oh wait
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.
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
Connection reset by peer.
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?
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.
Wait, nobody came up with this before?
brb chucking my batteries in the oven
it’s a cheap and easy thrill
Thanks, climate change.
this feels like bait
In reality, this doesn’t affect the existing batteries we have, it’s just for future battery technology.
