Developing an effective recycling process for reclaiming valuable metals from lithium-ion batteries is urgent issue owing to increasing battery waste electric vehicles. In this study, we developed a leaching method that enables the direct separation of lithium other critical metals, namely, nickel and cobalt, using two-phase system consists deep eutectic solvent (DES) water. The DES consisting 4,4,4-trifluoro-1-phenyl-1,3-butadione tri-n-octylphosphine oxide showed highest performance when combined with Several operational parameters, such as aqueous fraction, solid-liquid ratio, reaction time, operation temperature, were evaluated. optimum results in obtained 1:1 DES-water ratio 10 g/L reacted at 80 °C 24 h. An in-situ stripping phenomenon was observed, revealing transferred phase phase. application black mass leaching, significantly enhanced Co, Ni, Mn extraction into thus plays important role separating metals. efficiency reached 99% within
