Lithium is not that limited, current reserves are based on current exploration. More sources will be found and exploited as demand grows.

And if you want an alternative, sodium batteries are already coming online.

In fact, the limiting element for Li chemistries is generally the Nickel. Pretty much everything else that goes into these chemistries is highly available. Even something like Cobalt which is touted as unavailable is only that way because the industrial uses of cobalt is basically only li batteries. It's mined by hand not because that's the best way to get it, but because that's the cheapest way to get the small amount that's needed for batteries.

Sodium iron phosphate batteries, if Li prices don't continue to fall, will be some of the cheapest batteries out there. If they can be made solid state then you are looking at batteries that will dominate things like grid and home power storage.

AFAIR Cobalt is also kinda toxic which is a concern.

But as far as that and

Isn't that part of why LiFePO was supposed to take off tho? Sure the energy density is a bit lower but theoretically they are cheaper to produce per kWh and don't have any of the toxicity/rarity issues of other lithium designs...

It's also very recyclable, so big batteries that reach end of life can contribute back to the lithium supply.
