I get the cost, but it should be an option to upgrade any current EV to this new style battery.
How viable would something like this be for powering a home? Solar panels+this?
Not very. There's a different sodium based battery being designed for home storage. Not nearly as energy dense, but will last a very long time, can be left outside the house, and uses cheap components (no lithium or other rare metals).
That's the battery you'll want.
How much is that in loading cable diameter?
This is a most excellent place for technology news and articles.
