They don't mention it in this article but the big positive going for Sodium batteries is the cost, they are half the price of li-ion per KWH and about a third the price of Li-Pho. There are already quite cheap Sodium battery based cars out from BYD and while they are the lower range end of things (200 miles) they are also considerably cheaper.
So I think Sodium will find its way into the lower range EVs and home/grid storage since its so much cheaper. But I don't imagine we will want less power in phones or laptops as sodium is bigger and heavier.
