Electric cars are no longer held back by crappy, expensive batteries

Sodium batteries run at very high temperature and are finicky. They have been used for decades on submarines where they can be managed by trained personnel and where a large heat sink is available. I would be wary of consumer sodium based batteries.

I think that's sodium-sulfur batteries. There is work being done on sodium ion batteries. And also aluminum ion batteries. In thoery these are both similar to lithium ion batteries. In practice figuring out how to produce high quality ion batteries is not easy.
