> It is unavoidable that in the long term the cost of sodium batteries will be much lower than of any lithium batteries.

The question is, will it be meaningfully lower?

if processes are mature, and because of economies of scale the difference comes out to something like a few cents (or less) per cell... at that point it might become meaningful to ask if the density becomes in play again.

Sure for grid density is not an issue, but installing and setting up a pack still has a cost... so let's say the cost saved by sodium allows them to buy an extra pack... but lithium's density allows them to save the headache of installing that extra pack... won't it even out?
