There are mid Sodium Ion based EVs that do 150 miles and they are maybe $10k. Sodium Ion wont be able to get to the 300+ mile mark as they are heavier and bulkier and longer ranges will be dominated by li-ion and the upcoming almost solid state li-ion but that 150 miles covers a lot of peoples usual daily scenarios. The extra topping is the batteries last a lot more cycles too (6000) so after your car has long fallen apart you can use it in your home to buy cheaper night power or for solar storage.
Iirc sodium ion is more akin to LiFePO4 in energy density. Sodium ion battery tech is also fairly immature compared to lithium ion batteries, so we have lots of room for improvement
