The wide application of Li metal anodes is hindered by the inhomogeneous growth of Li dendrites. Herein, we propose an ultrafast microwave-induced synthesis method for a lithiophilic 3D porous mesh skeleton converted by commercial brass mesh. Due to the lithiophilic oxides (FeO and CuO) granular layer and 3D porous structure, this novel skeleton can be used as a current collector to achieve a high-stability of Li metal anode. A dendrite-free deposition morphology Li metal anode is obtained with noticeable cycling stability up to 1000 h (2500 cycles) at 5 mA cm⁻² current density with 1 mA h cm⁻² capacity. This skeleton is used to assemble the full-cell with the commercial LiCoO₂ (LCO) cathode. A stable full-cell is obtained with 87.2 % capacity retention after 500 cycles at 0.5C. The microwave-induced synthesis method in this work can prepare 3D lithiophilic skeleton in a brief period, which provides guidance for the design of Li metal anode.

锂枝晶的不均匀生长阻碍了锂金属负极的广泛应用。在此，我们提出了一种超快微波诱导合成方法，用于由商业黄铜网转换的亲锂 3D 多孔网格骨架。由于亲锂氧化物（FeO和CuO）颗粒层和3D多孔结构，这种新型骨架可以用作集流体以实现锂金属负极的高稳定性。^{获得了无枝晶沉积形态的锂金属负极，在 5 mA cm -2}电流密度和 1 mA h cm ^-2容量下具有明显的循环稳定性，最长可达 1000 小时（2500 次循环） 。该骨架用于与商业 LiCoO _{2组装全电池}(LCO) 阴极。在 0.5C 下 500 次循环后获得稳定的全电池，容量保持率为 87.2%。本工作中的微波诱导合成方法可以在短时间内制备出3D亲锂骨架，为锂金属负极的设计提供指导。
