Solar panel production doesn't use lithium. They're made from sand and a lot of energy. A bit like silicon wafers.

You might mean the storage to keep those data centers running throughout the night though and yeah. But this problem is not very big in the scope of other battery challenges like transportation. Because for data centers you don't need the best energy per weight or volume which you do need in a car.

And there's other sources of renewable energy too.
