Oh look it's the quarterly "revolutionary battery tech incoming" article.
With a small but significant difference: it's in production already.
where can i buy one ?

They might be a bit bigger than you want for home.
Re: Sodium-ion "salt" batteries will revolutionize electric-vehicle and grid storage
#53Something to be aware of, and this is still in flux as the market is so new, but when sodium-ion batteries that use Prussian Blue/Prussian white cathodes enter thermal-runaway (or catch fire for whatever other reason), they release hydrogen cyanide gas. Obviously manufacturers are aware of this and other chemistries of sodium-ion exist, but when a market is new you can sometimes get all manner of competing tech float…
Lithium batteries will also produce HCN in a fire. I believe sodium batteries actually produce less than lithium, but I do not have a primary source handy.

#54It is time to standardize EV batteries like wheels: 5-10 mainstream types & competition on quality vs. price vs. range. Regulator help is needed here.

I don't like the impulse to regulate, especially as a formative measure. Regulating new technology before industry has time to experiment seems like a recipe for high prices, few choices, and low competition.

CATL isn't the first to put sodium-ion batteries into production, but they are the first large established manufacturer to do so, so chances are they won't go bankrupt before production ramps up to general availability.

#57There is no reason I can’t put a swimming pool size battery under my house. I don’t care what the energy density is, make it bulletproof and cheap and massive.
"There's no reason" just "make it safe and cheap in huge size". Kind of like there's no reason we can't go to Mars for tourism. Just make it as convenient, safe, and cheap as a jet to London.
I failed to land my point, it’s that instead of chasing small and complex battery systems to put in cars, lower tech, bigger, less convenient battery tech of the pool-under-house scale, could be an incredible option. Stationary batteries don’t have the same constraints as the portable batteries we are familiar with from even before the lithium ion age.

Ask your local fire department about putting fires out in battery-powered cars versus gasoline cars. Yes, there is a qualitative difference and it's not in favor of the battery-powered cars. That's not to say that it's a stopper for them; it's just part of the cost/benefits analysis. The idea of technologies that are better on all parts of the cost/benefit analysis at once is a science fiction or video game concept.…
If I'm not mistaken, a lithium battery grid-level energy storage firefighting protocol is "evacuate people and let it burn."
Same protocol for a burning pile of tires at your favorite bumrocks exurban service station, amusingly. Yet no one loses their shit on HN about that horrifyingly dangerous technology.
I give up. This is a proxy war for something else. No one seriously is scared of batteries in the way people here keep trying to justify.

Why so sensitive? There are other battery chemistries (say, VRFB) that are less dangerous and that are less like tire fire.
