Abstract: This research introduces a universal, eco-friendly methodology tailored for the efficient selective extraction of lithium from both single and mixed cathode materials. Achieving impressive selective leaching efficiencies of lithium, the method reaches 99.51% for LFP and around 90% for NMC111, with a remarkable increase to 97.24% in mixed cathode scenarios due to the lowered activation energy. The extracted lithium is refined into lithium carbonate, attaining an overall recovery efficiency of 95% and a battery-grade purity of 99.6%.
