Selective lithium recovery via solubility-driven cobalt elimination in supercritical CO2: A new strategy for recycling lithium from spent lithium-ion batteries
• Lithium was selectively transported by P(B12C4EMAAm- grad -FDA) copolymer. • Cobalt was eliminated from the system by strongly chelating ligand bipyridine. • Lithium and cobalt recovery yields were found to be 40% and < 2%. • Lithium-cobalt separation factor was increased from 6.2 to 34.8 (5.6 folds).
