💡 Novelty & Significance:
This work pioneers a synergistic recycling strategy, using carbon from spent lithium-ion battery anodes and recovered transition metals to synthesize low-platinum medium-entropy intermetallic Pt(NiCoMn)₃. The catalyst induces lattice distortion and electron redistribution, optimizing Li₂O₂ kinetics. It achieves 0.35 V overpotential and 319 cycles, offering a sustainable, high-performance route for lithium–oxygen batteries.
