Cue dumbasses tossing their iphones in the toaster oven in 3… 2…
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
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
putting it over the stove.
¿Que dumbasses?
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?
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
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.
rolls of film
Oh right, those were stored in the fridge… weird to think about it.
Wait, nobody came up with this before?
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.
brb chucking my batteries in the oven
it’s a cheap and easy thrill
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.
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!
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
brb, putting e-bike battery in oven
One simple trick to make your ebike fly.

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.
Who greenlit this article ?
Yes but how can shareholders profit from this??
By not switching to Na based batteries and keeping a lid on Li mining.
Even BYD is betting on Na tho.
By making battery renewing devices.

Sounds like “microwave to charge” for the modern era.
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
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.
it would almost certainly need to be done at a fast charger, not at home unless it could do only a few cells at a time. Remember the golden rule: “Don’t set the house on fire by overloading the wiring”.
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.
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.
this feels like bait
In reality, this doesn’t affect the existing batteries we have, it’s just for future battery technology.
