While you're not wrong, sodium batteries coming on the market have 200 Wh/kg. This is comparable to where LFP batteries were a few years ago. That means the newer sodium batteries are about as good as what's in lots of EVs right now.

The ceiling is going to be lower than with lithium. Sodium ions themselves weigh about 3 times more than lithium, for the same +1 charge. So it's not just that sodium is a certain number of years behind lithium. It's that it'll likely plateau at a point permanently behind where lithium will likely be.
