Sodium-Ion is still valuable because Sodium is in resource abundance and more importantly, is a mineral which can't be used as geopolitical leverage (at least until large scale asteroid mining becomes a thing).
One of the largest sectors for generating value in the next 100 years, will be mass production of energy dense LiOn batteries for species scale energy storage.
