The draw-back with sodium batteries needs to be known, because they won't replace lithium anytime soon.

The density is lower, which is a great problem in EVs.

Not trying to be negative, but for an EV, or anything handheld, you get more weight for less power. Which is essential in a car, that uses more power the heavier it is.

What sodium IS the best at, are use cases where weight and size doesn't matter. Like with battery farms.

In this case they are much better than lithium.

What other benefits do they have? Do they have less wear or are cheaper per Wh to produce?

Or at least, about to be when production ramps up further?

They are dirt cheap, don't have the fire safety issues as some lithium chemistries (not all lithium chemistries do that), and sodium is abundant.

Well, sounds great for any non mobile storage then. Don't think anybody cares whether their 10kWh solar battery is twice the size and weight if it's half the price.

Thank you :)

It's also great for grocery getter cars where total range isn't super important. Current EVs are ~250 miles range and top out around 300-400, which is insufficient as a gas replacement for road trips but overkill for a commute or around-town car.

There are a lot of use cases for something inexpensive but technically inferior.
