Are Lithium-Ion Batteries Too Expensive for Storage?

I often wonder why Lithium is used for anything other than mobile applications such as vehicles or personal devices.

For stationary applications Sodium is nearly as good, the weight is a less critical issue and the batteries are about 2/3rd the price.

IMO the supply of Lithium batteries for stationary storage will mainly come from redundant EV batteries which have lost a proportion of their capacity but are still functional.

Otherwise better options for storage and fast response are Pumped storage;

and Regenerative rail

Because it was easier to go with the lithium flow? I'm not sure anyone thought how much storage we'll need with all the renewable installations.
