Aqueous zinc-ion batteries have gained interest as large-scale energy storage devices due to their high stability, low cost, and abundant reserves. However, a problem exists that the formation of dendrites due to the unstable zinc stripping/plating behavior of zinc reduces the cycle stability of the cell. In this paper, Zn@ZIF-8 anode is introduced to solve the problem of unstable plating/stripping behavior and realize a long-cycle aqueous zinc ion battery. The microchannel structure of ZIF-8 was able to induce uniform zinc stripping/plating behavior. As a result, a runtime of 5500 h under 1 mA cm-2 and 1 mAh cm-2 conditions was obtained in a symmetrical cell analysis, which is higher than that of a conventional bare Zn symmetrical cell. In addition, by introducing a PVDF binder-based Zn@ZIF-8 anode, side reactions at the electrolyte and electrode interface could be suppressed, thus inducing stable redox reactions.
