Wait… did they do all three?
“Global action requires working together to access critically important materials,” Meng said.
So… nope.
Huh ?
What information are you trying to convey by quoting that sentence from the article?
I know colonizer-speak when I see it.
I know everyone wants to point out that she may be referring to the brutal colonialist exploitation that lithium ion battery technology rests upon - but the way the quote is placed and framed tells me instead that we are not being told everything about this “techno-miracle.”
If materials are not easy to access, then it won’t scale cheaply.
Any way to read the paper published without subscribing to nature?
Calling BS
No batteries are ever anode free so you are right to call bullshit on this title …
Yet, what they meant was that, at the time of fabrication, there is no sodium at the anode side and only while charging the battery, sodium is deposited so creating the anode.Also BS because this is such a common BS article “Amazing breakthrough in batteries will change everything and is 100 times better!”
Always BS
I’ve been reading about various breakthroughs in battery world for past decade or so. So far none ended up in a consumer product.
I’ve been reading about battery breakthroughs for decades. And I remember when the latest in battery tech was alkaline, then Ni-Cd, then Li-Ion, and now LiPo. All of those have ended up in consumer products.
Also, the battery pack for a cell phone 30 years ago was about the same volume and weight of an entire smartphone, with a capacity of about 500 mAh. They are also far cheaper if you account for inflation.
Batteries have improved incapacity by about a factor of 10 and the cost per watt-hour has reduced by about 99% in the last 30 year. All without a single advancement in the technology, apparently.

All without a single advancement in the technology, apparently.
What do you mean by that?
I would say there have been a great many advancements in technology. I mean, that’s what all these improvements are, right?
It was sarcasm, which seems to be harder to convey in text than any number of battery advancements.
You skipped Ni-MH there, that was major for not having the memory problems of Ni-Cd. We still use those in AA and AAA rechargeable batteries.
Ni-MH production for EVs was effectively shutdown by Texaco and later Chevron through patent acquisitions.

totally TIL worthy
Holy shit. I had no idea.
Chevron is pretty fucking evil for a lot of reasons, but we’ll add this one to the pile, I guess.
Ni-MH
iswas also in a lot of hybrid cars.
This seems like a pretty big deal, right?
Indeed, the fact that they filed a patent is also an indicator that this is not purely an experiment, but a tangible way forward. Let’s hope this can scale up quickly.
There’s a pile of battery patents that are all game-changing but when a company decides to make a dedicated factory that’s when you know shit is going down.
Eh, the patent office hasn’t had standards for practically for like a century, just that you describe a novel method
it’s not just another article about a new revolutionary discovery because that’s the only way to have funds?
Yup. Studies on sodium batteries has been going on for years. If they finally achieve good enough state this is big since lithium is limited and expensive while sodium is everywhere. However sodium batteries will never be effective as lithium batteries because of the atom size. Lithium is much smaller than sodium.
True, but this is solid state so it may be higher density than current Lithium based batteries. But it might not beat a hypothetical lithium solid state battery. On the other hand, sodium batteries today beat out lithium in many other ways than capacity, and if those things are true for solid state then as long as there is a big enough jump in capacity due to the solid state transition then I think sodium is going to be the go-to for most uses in the future.
Don’t actually know about density differences but I’m quite positive that sodium batteries will be used in many sectors because it will be much cheaper. Probably not on cars, maybe not on phones as well. It will be enough for all other small appliances I think.
Well we are in dire need of grid size storage so this is excellent then.
