摘　　要：One of the main reasons that limit the application of aqueous zinc ion batteries(ZIBs)is the growth of zinc dendrites.In this paper,three different sizes of UiO-67 were synthesized,named B-10,B-15 and B-20,by hydrothermal method and their different performances in ZIBs were compared.Among them,B-10 has the smallest size,larger porosity,as well as a high content of Zr-OH/H_(2)O groups which are excellent zincophilic sites.It is also noteworthy that zinc symmetric batteries composed of zinc foils coated with B-10 have excellent zinc plating/stripping performance at different current densities,with minimal overpotential and up to 700 h of cycling stability at a current density of 0.5 mA·cm^(-2).B-10 also has the lowest resistance and highest ionic conductivity compared to B-15and B-20,and has the best ability to inhibit zinc dendrite growth.
