There is a big shift in prices coming with Sodium Ion batteries. At about 1/4 the price of Li-ion they save substantial money all be it a little less dense. For all but the highest range cars Sodium Ion is going to do the job and BYD is talking about $12000 cars. Not quite a cheap car yet but still given the savings electrical vehicles bring on running costs its a significant step.

Its not just volume production the materials in the batteries are driving a lot of the high price. You can get a second hand Zoe for £4-5k but they are quite limited in range. A full range EV for £12k is going to be a big deal.



Sodium Ion energy density isn’t the best, it’ll probably impact grid storage more. For cars that need less than 200 miles of range I agree though.
