I know I shouldn't reply to your FUD but it's too funny not to sometimes. I'd already read about Natron and their Sodium ion batteries before seeing your post and the important fact you left out which you could easily find on their website is below (I also note they use Wh/l not Wh/kg). The reason they are building Giga factories is because EVERYTHING is going electric so there's plenty of room for some LARGE and HEAVY Sodium batteries, mostly in BESS or similar applications.

Right, Devo, look at me, look at moiee, Lithium is lighter than Sodium. Now wipe that egg off and go do some bloody research!
