At the right price, there is no shortage of lithium capacity. What is in short supply are the reserves of lithium that can be extracted at relatively low cost, which generally come from salt flats in places like Chile; there are few such resources in the world. On the other hand, there is a vast amount of spodumene mineral which can be converted into lithium at a higher cost. And theoretically (say, in 100 years), there is plenty of lithium in the ocean; it would just take a much higher price per pound of lithium to justify extracting it.
