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.

I bought 18650 sodium-ion batteries last year. Price is about the same as lithium-ion in small quantities, capacity is about half.

But this is currently small batches backyard production, so I expect the prices to go down. Also, the materials are available practically everywhere, so even 3rd world countries should be able to make them.
