Schematic illustrating the synchronous activation of carbon and oxygen bonds in spent LIBs: By leveraging graphite from anode materials, the HKUST team promotes interfacial carbon–oxygen bond activation, which accelerates the thermal decomposition of nickel–cobalt–manganese (NCM) cathodes at significantly lower temperatures—enabling efficient recovery of lithium carbonate (Li₂CO₃) and transition metal oxides (Ni, Co, Mn) for closed-loop recycling.
