While lithium extraction technologies generally focus on ways to get the essential metal out of the ground, there’s another source to mine: existing batteries that no longer work. A new technique could now make that process economically viable.
Idk where they got the picture from but 4300mah in aa size would be insane. Thats like 2.5 times as much capacity as how much the best ones provide currently.
It’s probably an AI gen image.
Was gonna say maybe they’re 18650s but it Def says AA on them. I’m gonna go with it’s a made up / AI-generated image
Yeah probably tho i kinda wish they existed lol
They would have to be 21700 cells to hold 4.3AH. 18650 cells top out around 3.6AH. While it is possible to make higher capacity cells, there are some major downsides with doing so.
It’s just a stock photo used since at least 2017 that appears to have had the 4300mah text added on more recently.
Looks like AI to me. Also, those would most likely be NiMH batteries, which AFAIK don't have any lithium.
The way its packaged with the indent at the top would make it a lithium cell but yeah its fake anyways
In case anyone’s curious: it is likely a cell wrapper misprint/typo.
4300mWh AA lithium ion cells are a standard extended-life chemistry. 2866 mAh is their actual rated capacity.
Maybe they’re just ultra fire batteries?
There are plenty of cells that size over 3000mah.
The highest capacity one that is properly commercially available is the vapcell f15 which is known for quality control issues. Its advertised capacity is 1500mah but multiple sources measured it at an actual usable capacity of 1250-1350.
That means battery prices will be coming down, right? Right?
No. For a process to have an impact to the economy at large it must either be substantially cheaper or be given enough time.
You say that like they havent been? The price per kWh for lithium batteries has been consistently falling for over a decade. I see no reason to believe that this tech wouldn’t result in further price decreases if it could be built at scale.
If this truly works, that would be fantastic news, but getting clean lithium out of a used battery that has been degraded and the lithium has become contaminated sounds extremely complicated, so I’m still a bit skepical on the feasibility of it.
The process honestly sounds to me a little bit like decaffeination, which also feels like witchcraft to me. So it might work!
🤞 a paper comes out.
Not related directly to the article, which I found interesting, but I’d never heard of this website before and there seems to be many great articles on it! Another website to follow for me!
Bullshit, just like we can replace fossil fuels by making algae biofuel (leaving out the part where there’s no possible way to scale that enough to do ANYTHING)
May well be bs but for different reasons.
Algae is an alternative fuel and has no link to fossil fuels. This takes an existing but expired fuel and extracts usable material, or so it says. In any case they aren’t comparable.
Comparable in that it’s presented as a solution to a problem when it’s really not a solution at all, I meant

I have a hard time believing it’s cheaper than from my local lithium guy.

I have a slight suspicion we’re not talking about the same lithium here

Stop it before you give some MAHA influencers the idea for a new “ditch your mood stabilizers, lick used batteries instead!” trend… 😵

That’s the advantage of sourcing it locally, of course. I have a feeling these guys have gamified lithium collection through an app like uber or grubhub or airbnb, ultimately taking all the advantage we once had for simply being local…

Yeah, but with him you gotta go over to his shitty apartment and let him charge a bit to make the deal
