So does carbon, oxygen, hydrogen, and other elements that bond to make oil. It's not lithium by itself that becomes a battery, but some complicated chemical compound of which lithium is a vital and hard to get part. C, O, H can be recombined into crude oil, gasoline, diesel fuel, natural gas, etc. at the expense of a certain amount of energy. Similarly, extracting lithium from an old battery and turning it into a new one requires energy. I wonder how much energy is needed (in both cases - lithium-to-battery and carbon+hydrogen-to-oil).
