The main drawback of using sodium instead of lithium was energy density and weight. Sodium-ion batteries achieved something like 150 Wh/kg, compared to well over 200 Wh/kg for lithium-ion batteries. That’s a competitive disadvantage that our market-driven economies simply would not tolerate at the time.

Sodium ions are three times heavier, too. Even though the sodium component accounted for only about 5% of the overall battery weight, it still made them heavier than their lithium-based cousins.

There would be still a huge market for stationary batteries where price and availability is more important than weight or power density. This market is still dominated by lead-acid batteries, that Sodium batteries easily beat performance wise.

agreed. my opinion besides that article is that there shall be no market. this should be DIY/T(together) and easy to build yourself. cause the market sucks. also i'm really desperate of seeing fellow human beings believing in such technologies to save us for a brand new green capitalist system. it won't work, we have to listen to the indigenous, they don't need no batteries, we really consume to much we destroy the world of them, of animals, of plants, of everything. no more markets. DIY/T forever!
