Sodium-based batteries currently have a lower energy density than lithium-based batteries so they are only useful in some applications.
-
Mainly for cheaper applications which are not as weight (and size) sensitive. One example is entry level EVs or home energy storage.

It sounds like they need to do a lot more work to increase the cycle life.

That's usually the problem with these ultra high capacity batteries. The electrode structures just don't hold up
