Rapid extraction of valuable metals from spent LiNixCoyMn1-x-yO2 cathodes based on synergistic effects between organic acids

•Valuable metals of spent LIBs were leached efficiently by AA-assisted VC route.•The leaching efficiency was improved by ∼ 90% compared to single acid system.•Additional reducing agents were not required.•DFT calculations were introduced to evaluate the intensity of synergistic effects. The slow rat...
