This study explores the use of a deep eutectic solvent (DES) composed choline chloride and pyrogallol (1:1 molar ratio) for recovery lithium, cobalt, nickel from spent lithium-ion battery cathodes based on LiNi0.33Co0.33Mn0.33O2 (NMC111). The DES exhibits moderate viscosity, intrinsic redox activity, strong complexation ability, enabling efficient metal dissolution under mild conditions. effects both temperature (50–80 °C) time (up to 12 h) leaching efficiency were systematically investigated. Optimal parameters—80 °C, 8 h, liquid-to-solid ratio 50—yielded extraction efficiencies 92% Li, 85% Co, 88% Ni. Kinetic modeling indicated pseudo-first-order behavior with activation energies 26.6, 22.1, 25.2 kJ/mol Ni, respectively. Mechanistic analysis confirmed dual role as reducing agent (facilitating Co3+ Co2+ conversion) chelating ligand.
