Thank you. What if I reframed the question to: What amount of lithium is currently extractable at an effective cost and how long does it last if we replace every vehicle on the planet with an EV overnight. My searches seem to come to a number of ~14million tonnes which seems to be enough for ~1.4b Tesla's(at ~10kg of lithium each) Is my math here wildly incorrect or maybe I am not understanding the potential for increased extraction at a reasonable cost?
