Uneven lithium (Li) metal deposition typically results in uncontrollable dendrite growth, which renders an unsatisfactory cycling stability and coulombic efficiency (CE) of Li metal batteries (LMBs), preventing their practical application. Herein, a novel carbon cloth with the modification of ZnO nanosheets (ZnO@CC) is fabricated for LMBs. The as‐prepared ZnO@CC with a cross‐linked network significantly reduces the local current density, and the design of ZnO nanosheets can promote the uniform deposition of Li metal as lithiophilic sites. As a result, the Li metal anodes (LMAs) based on ZnO@CC (ZnO@CC@Li) enables a long cycle life over 640 hours with a low overpotential of 65 mV at a current density of 4 mA cm−2 with a capacity of 1 mAh cm−2 in the symmetric cell. Moreover, when coupling the ZnO@CC@Li with a LiFePO4 cathode, the assembled full cell exhibits excellent long cycle and rate performance, highlighting its promising practical application prospect.

通过 ZnO 纳米片改性碳布的定点锂沉积实现稳定的锂金属阳极

不均匀的锂（Li）金属沉积通常会导致不可控的枝晶生长，从而导致锂金属电池（LMB）的循环稳定性和库仑效率（CE）不理想，阻碍了其实际应用。在此，制备了一种用于 LMB 的改性 ZnO 纳米片（ZnO@CC）的新型碳布。所制备的具有交联网络的ZnO@CC显着降低了局部电流密度，ZnO纳米片的设计可以促进锂金属作为亲锂位点的均匀沉积。因此，基于 ZnO@CC (ZnO@CC@Li) 的锂金属负极 (LMA) 可实现超过 640 小时的长循环寿命，在 4 mA cm−2 的电流密度下具有 65 mV 的低过电势，对称电池的容量为 1 mAh cm−2。此外，当ZnO@CC@Li与LiFePO4正极耦合时，组装的全电池表现出优异的长循环和倍率性能，凸显了其广阔的实际应用前景。
