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.

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
> In fact, the limiting element for Li chemistries is generally the Nickel
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 the exact reason LFPs are taking off, especially in grid storage scenarios.
The high cycle life combined with the fact that all the materials are easy to acquire and dirt cheap.
LFP cells have long since taken off. Tesla has been making vehicles with LFP battery packs for half a decade now.
