摘要

A closed-loop recycling route for spent LiCoO₂ batteries, converting metal resources into high-value electrocatalysts with environmental and economic merits. Synergistic microwave plasma etching and hydrothermal method enable precise construction of Co₃O₄/NiFe-LDH heterostructures, optimizing material surface and interface properties. Charge redistribution at the heterointerface regulates oxygen intermediate adsorption, providing a new interfacial engineering idea for low-cost water electrolysis catalysts.
