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.
Article says operating temperature range. -20 to 60 C
Lithium batteries are often -30 to 80C, but that's just saying what's possible to squeeze some kind of voltage out of them. Basic principle is that the colder it is, the harder it is for chemical reactions to happen, and thus this will affect all chemical batteries to some degree.
