Zinc dendrite, active iodine dissolution, and polyiodide shuttle caused by the strong interaction between liquid electrolyte solid electrode are chief culprits for capacity attenuation of aqueous zinc-iodine batteries (ZIBs). Herein, mullite is adopted as raw material to prepare Zn-based solid-state (Zn-ML) ZIBs through zinc ion exchange strategy. Owing merits low electronic conductivity, diffusion energy barrier, adsorption capability, Zn-ML can effectively isolate redox reactions anode AC@I
