Fair points. I heard somewhere (probably here) that they were working on sodium solid state batteries or something. I look forward to new developments.
There's been "new" battery technology in the works since we starting using lithium ion and nothing so far has come anywhere near close enough to replace it. Sodium just like all the other "exciting" failed ideas in the past decade isn't gonna go anywhere either.
Sodium batteries on the infrastructure level would work wonderfully but you'll never see them in your phone or even a car. The energy density just is shit. There would need to be some unexpected advance in the technology to gain ~50% energy density just to meet lower end lithium ion.
But really electric cars aren't the future anyway what we need to invest in is public transportation. Electric busses, trains, trams, hell why not self driving scooters that's way more practical than a whole ass car.
