Chile is sitting on the largest deposit of lithium in the world, by far. And Bolivia has the second largest. If Push came to shove we can extract it from sea water.
Well, that’s just great. When they figure out how to make a lithium ion battery without lithium manganese dioxide, 97% of which is in China, then Chile will be in the driver’s seat. (rolls eyes) BTW, Nevada has quite a lot of lithium also.
