Constructing Oxygen‐Vacancy‐Rich ZnO/CuO Oxide Lithiophilic Interlayer on Carbon Cloth for High Mass Loading and Stable Lithium Metal Batteries

To address the challenges of unstable interface and dendrite growth in lithium metal batteries, this study developed an oxygen‐vacancy‐rich metal oxide modified carbon cloth (O V –ZnO/CuO@CC) using a solution‐based coordination assembly method followed by thermal treatment. The synergistic integration of ZnO and CuO, coupled with the introduction of oxygen vacancies, significantly enhances the lithiophilicity of the 3D framework. Electrochemical results reveal that the composite anode exhibits exceptional electrochemical activity, characterized by a markedly suppressed lithium deposition overpotential of merely 7.8 mV and a low overpotential of 20 mV in symmetric cells. These properties effectively accelerate the charge‐transfer kinetics and guide uniform lithium nucleation. When paired with a high‐loading LiFePO 4 (LFP) cathode (10 mg cm −2 ), the Li@O V –ZnO/CuO@CC||LFP full cell delivers a high specific capacity of 150 mAh g −1 at 0.1 C, demonstrating superior interfacial electrochemical reaction even under demanding mass‐loading conditions.
