The lanthanum fluoride layer functions as an insulator, and its corrosion resistance and low polarization contribute to the facilitation of zinc ion diffusion while suppressing hydrogen evolution, thereby effectively reducing electrode interface impedance. In this paper, a precipitation method was employed to prepare a spin-coated lanthanum fluoride coating on commercial zinc foil in order to investigate its impact on dendritic growth of zinc and electrochemical performance of the full cell. The results demonstrate that the lanthanum fluoride coating significantly reduces both nucleation energy barrier and overpotential for Zn2+. Zn@LaF3 symmetric cells exhibit exceptional cycle life (over 3 000 h) at a current density of 1.0 mA·cm-1. Even after undergoing 3 000 cycles at high current density, Zn@LaF3||VO2 full cells still retain 75.8% capacity (116 mAh/g), which is substantially higher than that observe in Zn||VO2 full cells (33 mAh/g). Utilizing lanthanum fluoride as a negative electrode coating for zinc provides a practical approach towards constructing dendrite-free zinc negative electrodes and achieving high-performance aqueous zinc-ion batteries.
