The burst demand of lithium-ion batteries (LIBs) for energy storage leads to an increasing production of LIBs. The huge amount of electrode scraps produced during the industrial production cannot be overlooked. A sustainable and simple method was developed to regenerate Li(Ni1/3Co1/3Mn1/3)O2 electrode scraps as new cathodes for LIBs. Three different separation processes, including direct calcination, solvent dissolution, and basic solution dissolution, were applied to obtain the active materials. Then, a heat treatment was used to regenerate the scraps. The effects of separation methods and heat treatment temperatures were systematically investigated. The results show that the scraps regenerated with solvent dissolution and heat treatment at 800 °C deliver the highest reversible discharge capacities of 150.2 mA h g–1 at 0.2C after 100 cycles with capacity retention of 95.1%, which is comparable with commercial Li(Ni1/3Co1/3Mn1/3)O2 cathodes. When cycled at 1C, a highly reversible discharge capacity of 128...
