The design of lithiophilic three-dimensional (3D) skeletons has proven to be effective in inhibiting dendrite growth and improving the Coulombic efficiency of lithium metal anodes (LMAs). However, for the 3D skeletons with homogenous lithiophilicity, Li would preferentially deposit on the top of 3D collectors, what's more, the intrinsic low electrical conductivity of metal-organic frameworks (MOFs)-derived oxides which are often employed as the lithiophilic materials on 3D skeletons affects their electrochemical kinetics. We firstly prepare MnO/Co/C derived from MnCo-MOFs on carbon cloths (CC) by a simple method and a composite anode (Li-CC@MnO/Co/C) is obtained. The synergistic effect of the electrical conductivity of Co and lithiophilicity of MnO facilitates their electrochemical kinetics. The Li-CC@MnO/Co/C composite anode exhibites long cycle life and low hysteretic voltage in the symmetrical cell with a high areal capacity and current density (5 mA h cm, 5 mA cm) and a steady cycle performance of 80 mA h g at 10 C for nearly 300 cycles in easter-based electrolyte. This work might propose a rational design for a high-performance LMA, particularly suitable for practical applications.

双金属金属有机框架衍生的亲锂性和导电性MnO/Co/C实现高性能锂金属阳极的间歇沉积模型

亲锂三维（3D）骨架的设计已被证明可以有效抑制枝晶生长并提高锂金属阳极（LMA）的库仑效率。然而，对于具有均匀亲锂性的3D骨架，Li会优先沉积在3D收集器的顶部，而且，金属有机框架（MOF）衍生的氧化物固有的低电导率，这些氧化物通常用作3D亲锂材料骨架影响其电化学动力学。我们首先通过简单的方法在碳布（CC）上制备了 MnCo-MOFs 衍生的 MnO/Co/C，并获得了复合负极（Li-CC@MnO/Co/C）。 Co的导电性和MnO的亲锂性的协同效应促进了它们的电化学动力学。 Li-CC@MnO/Co/C复合负极在对称电池中表现出长循环寿命和低迟滞电压，具有高面积容量和电流密度（5 mA h cm、5 mA cm）以及80 mA的稳定循环性能h g，在 10 C 下，在复活节基电解液中循环近 300 次。这项工作可能会提出一种高性能 LMA 的合理设计，特别适合实际应用。
