There 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.
Really hoping this enables safer battery tech too. Lithium fires are scary
And gasoline fires and high speed collisions aren't? This is the bit of paranoia around EV deployment that I genuinely fail to understand. Personal vehicles are by far the most dangerous apparatus with which we interact, already. And we're fine with it! Have you ever, even once , called a Civic or Vespa "scary"? But put a battery in it suddenly they need new tech before you'll be comfortable?
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. In the real world there's always a mixture of positives and negatives between two different technologies.
note sodium-ion is no longer two or three times the weight of lithium-ion, there is only a +33% penalty apparently the problem is there is not yet enough volume in production to compete on price, which I thought was the whole point? > sodium-ion specs have improved to the point that the technology could break into the general EV market.

I do wonder if there will be a convergence between sodium-ion battery architectures and cheaper, renewable-powered desalination. Could industrial seawater mining be competitive as a sodium feedstock source?

Why under the house? It can sit under your yard, no need to bother with so many tons of construction concrete on top of it.

My understanding about sodium though is that the performance in cold and heat is excellent. So even if you pay a penalty for weight, you can drop the thermal management, which saves quite a bit.
For grid storage, this chemistry will be a game changer. For vehicle, I think it has a ways to go before being preferred over LFP, but that's a guess.
Oh look it's the quarterly "revolutionary battery tech incoming" article.

doesn't burn like LiFePo4 so no fire risks, though I am not sure what a short-circuit would do in damage/danger
why even under a structure though, just do it like a septic tank?

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.
