If sodium batteries need less cooling(or none), they may not be too far off. Particularly when you get to comparing cold environment range loss, they may even come out ahead in Canadian winters.
The reason it caught my eye was specifically the cold temp ability for Canada.

These would probably replace the lithium phosphate batteries and even Tesla's are that high. It's not just the cooling issues for the lithium batteries, but the fire propagation suppression. About one in a million it so cells have a defect that can start fires so they put in stuff to stop it from showing cell to cell. You don't need that with the sodium batteries so I do think they'll eventually replace lithium phosphate in cheaper EVs
