Have a look at The Limiting Factor episode "The Hype and Reality of Sodium Ion Batteries" https://youtu.be/KjiqqafD_0w?si=txe6eODkSiasSylg

It's really well done and digs into all the details on sodium-ion. Lots to like with sodium-ion (charge rate for one) but cost isn't going to be competitive for at least 5 and more likely 10 years.

That video seems over pessimistic to me. It has "sodium ion battery cells don't have a good chance of reaching parity with LFP cells until about 2039" but BYD who are making the things are talking about next year.

I could see quite a rapid takeoff if they prove successful next year after being mass produced because they look like maybe the best solution for grid storage.
