lots of lithium is potentially available, most of it come from brines today.
large amounts of lithium are not needed in batteries. Lithium is abundant in nature, just not highly concentrated.

the main expense of Tesla's batteries is raw materials and the most expensive part of those is the metals used in the electrodes. If BEV ever get even close to the 80 million per year cars made today, cheaper and more readily available materials are going to be needed to replace the nickel and cobalt presently used by Tesla.
