Lithium metal batteries are regarded as promising candidates for next-generation energy storage systems. However, their anodes are susceptible to interfacial instability due to significant volume changes, which significantly impacts the cycle life of lithium metal batteries. Here, a rapid method for the fabrication of 3D-hosts with interface modified layers is reported. A simple infiltration and heating process enables the transformation of copper foam into Zn-BDC-modified copper foam within 1 min, rendering it suitable for use as a current collector for lithium metal anodes. The Zn-BDC nanosheets with high lithiophilicity are uniformly distributed on the surface of the current collector, facilitating the uniform deposition of lithium and reducing the volume change. Consequently, the half cell exhibits a remarkably low overpotential (26 mV) at a current–density of 4 mA cm⁻² and is cycled stably for 1000 h. Furthermore, it demonstrates a significant enhancement in performance in the LiFePO₄ full cell. This study provides a crucial reference on the connection between the interfacial modification of the current collector and the lithium deposition behavior, which promotes the practicalization of lithium metal anodes.

快速制备的亲石框架通过改变锂沉积模式来稳定锂阳极


锂金属电池被认为是下一代储能系统的有希望的候选者。然而，由于体积变化很大，它们的负极很容易出现界面不稳定，这会显着影响锂金属电池的循环寿命。在此，报道了一种快速制造具有界面改性层的 3D 主体的方法。简单的渗透和加热过程可以在1分钟内将泡沫铜转化为Zn-BDC改性泡沫铜，使其适合用作锂金属负极的集流体。具有高亲锂性的Zn-BDC纳米片均匀分布在集流体表面，有利于锂的均匀沉积并减少体积变化。因此，半电池在 4 mA cm ⁻² 的电流密度下表现出非常低的过电势 (26 mV)，并稳定循环 1000 小时。此外，它还证明了 LiFePO ₄ 全电池性能的显着增强。该研究为集流体界面改性与锂沉积行为之间的联系提供了重要参考，促进了锂金属负极的实用化。
