Thanks, I wanted to know about price. Isn't that the main benefit of sodium-ion. On par energy density with LFP, but a lot cheaper.
Think of it this way, Sodium metal is abundant and cheap with 30x the energy storage (and energy transfer) of other solutions yet nobody has used it in almost any product ever (including as a coolant). The volatility of Sodium is why. Unless they have a solution to this, then I would be shorting whoever is insuring these batteries.
You should also consider shorting Morton [0]. They sell sodium, combined with chlorine, one of the nastiest elements around! And for products that go in people's homes! On food!
It should be noted that most manufactures aren't doing pure Na-ion. They are mixing in a little Na with the Li to stretch Li supplies and gather data on the impact of the increased volatility on safety. I wouldn't expect their first use to be in cars. I would expect them to be in grid stabilizing batteries.
I was thinking of the aqueous sodium ion batteries, which do not have the issues described. I thought those were the ones that are commercially available, but that's not the case.
Nowadays, the manufacturers of refined table salt present you with a digusting proposition: sprinkle this worthless elemental sodium-chloride onto your food, because it is "salt" and they are 100% trading on its ancient reputation. Perhaps it is better to simply trample it underfoot?
Unfortunately, all the trace minerals are missing from refined salt. That pure white, homogeneous, translucent quality gives it away. The refining of salt is done purposefully, because the trace minerals are more valuable to supplement vendors.
All those trace minerals are separated out and sold out to companies who will assemble them into expensive dietary supplements. Your magnesium, and selenium, and zinc that you pay $30 a bottle for.
And that is also why sodium has such a nasty reputation in 2026. If you get CVD then you avoid sodium. If you get hypertension then you avoid sodium. Sodium is avoided like the plague. No physician will recommend sodium or table salt for a diet! Why should they? Adding sodium no longer introduces trace minerals or nutrition, it only introduces saltiness.
It is still possible to find unrefined salt. It may be sold as "sea salt" or "kosher salt" but you'll need to find it in transparent packaging. If it contains impurities that look like pepper or dirt, then it is unrefined. If it is imprinted with the obligatory fake warning about iodide, then it may be unrefined. (The mandatory FDA "iodide" warning is not only fake, it's misleading and downright malicious.)
Good luck with your salt! With love from your eponysterical HN noob!
However, the information is false. The amount of nutrients in unrefined salt is negligible. Yes it contains trace minerals but not in any significant quantity.
I have never seen or visited that website ever in my life. Why would I? I wrote my comment completely originally, and your accusation of bad faith is, in itself, bad faith.
In fact, none of the content which I typed into my comment is found in that blog article. How and why did you even find it? Anyone else here can read and confirm that I copied nothing. I quoted nothing. I owe nothing to anyone. My comment is original and copyrighted by myself (c) 2026, all rights reserved.

If they have not solved the problem, I still wouldn't recommend shorting any companies. Shorting a stock and waiting for years for it to drop is not a great strategy.
Huh? See https://www.terrapower.com/natrium/ -- and it's not exactly a new idea.
Also not uncommon to use sodium-filled exhaust valves in car, motorcycle, and aircraft engines.
In 75 years we won't need to extract more lithium - except the fraction needed to replace permanently-lost batteries.
Incidentally, you should be very careful when talking about "<resource> reserves", because the definition of a reserve is usually "<resource> that is profitable to extract" - and when we "run out", prices will go up and thus currently-unprofitable sources will become profitable, and POOF! Our <resource> reserves have increased, purely through the power of semantics.
Also, over the decades resource extraction becomes cheaper and thus more sources become profitable.
Personally though, I don't think any of that will matter -IMO the future is proton batteries, AKA Hydrogen batteries (which use an electrolyte of "ionic hydrogen", H+, which has 1 proton and 0 electrons - people claim lithium is the lightest metal, but it has 3x the protons of hydrogen). I think that the recent TABQ batteries, or something like it, will become commercially viable within 75 years (although who even knows what batteries will look like in the year 2101).
As for reserves, while you understand the economics you are missing the physics. For example, there is Li (and U) in the ocean. We don't extract Uranium from the ocean not only because it isn't economical, it isn't even energy efficient. This is because moving a billion tonnes of water takes more energy than the 3 tonnes of Uranium you would harvest from doing that. For Li, its takes just as much energy (and money) as its just as rare. In other words, there is a floor on that economic extraction argument specified by a positive EROEI (energy returned on energy invested).
If you have any other sources or information on why we can't recycle lithium please let me know. As far is battery failure goes it's a mechanical failure on a chemical level
The Li that comes out of the process you describe wouldn't be recycled. It would still be mostly exhausted. Specifically, something we don't understand about the structure of their electrons causes the batteries made with such material to have a far lower capacity than if you used freshly mined Lithium. My source is a Material Engineering class at MIT.
The lithium ions are the chemical process that actually store the charge, They move from the anode to cathode in charge and discharge. The loss of these ions is what causes the degradation of the battery which is a function of entropy here. It is simply that the concise arrangement that we required for this electro-chemical to take place falls out of balance.
Entropy problem is easily solved by mashing a battery up and reconstituting it into a new battery.
To put this all simply this is all fairly basic chemistry, even if there was some kind of structure being created that has a high bond enthrall we can still undo that with enough energy.
If you could maybe share some research or other information to back up your claims other than you went to a class at MIT i would really appreciate it also the company i was saying is called Li Cycle
They are always revising estimates up and down a bit. But Li demand just keeps rising and rising. And a single grid scale battery takes 10 years of current Li-ion battery production worldwide to build.
So do we have enough Li at current rates, sure. We don't have anywhere near enough to do anything like replacing even a fraction of FFs with renewables. I guess that's the real headline here. That's why people are experimenting with Na-ion. Putting it in a production car today, that seems...what's the word...homicidal. Making a grid stabilization battery (not for backup) with large amounts of space between cabinets to see what happens, that seems more wise.
I've seen that repeated a lot but I still can't buy sodium batteries cheaper than lifepo...
