1. A method, comprising:
mixing a lithium source including a transition metal with a solvent containing an oxidation reagent to oxidize the transition metal in the lithium source and extract lithium, forming an extracted lithium solution;
purifying the extracted lithium solution by precipitating and filtering impurities; and
precipitating the lithium in the purified lithium solution to generate Li2CO3.
