摘　　要：Aqueous zinc ion batteries(AZIBs)are promising energy storage devices.However,the formation of dendrites,hydrogen evolution,and corrosion reaction seriously affect their electrochemical performance.Herein,the synergistic effect of ion-migration regulation and interfacial engineering has been confirmed as the potential strategy by kaolin functionalized glass fiber separator(KL-GF)to alleviate these problems.The rapid and orderly Zn^(2+)migration was achieved to improve the transfer kinetics and induced uniform zinc deposition by more zinc-philic sites of KL-GF.Based on the interfacial engineering,the side reactions were effectively mitigated and crystal planes were regulated through KL-GF.The hydrophilicity of KL alleviated the corrosion and hydrogen evolution.Importantly,a preferential orientation of Zn(002)crystal plane by KL-GF was induced to further realize dendrite-free deposition by density functional theory(DFT)and X-ray diffraction(XRD)characterization.Hence,the Zn|KL-GF|MnO_(2)cell maintained a high discharge capacity of 96.8 mAh/g at 2 A/g after 1000 cycles.This work can provide guidance enabling high-performance zinc anode for AZIBs.
