A composite ion exchange membrane, a preparation method therefor and a use thereof, and a zinc-iodine flow battery. By introducing halogen adducts onto a porous membrane, a composite membrane based on a series of localized high iodine concentration (LHIC) coatings is constructed to suppress the problem of crossover of active polyiodide compounds in a catholyte. Specifically, metal oxides exhibit a strong physicochemical adsorption effect toward halogens, and halogen oxide adducts are formed, the halogen oxide adducts becoming effective halogen carriers. An LHIC coating is constructed on the porous membrane by utilizing the strong adsorption characteristic of the carriers and halogen (such as iodine), thereby enhancing the selectivity of the porous membrane toward iodine species. On the basis of Donnan exclusion and concentration gradient effects, a constructed localized high-concentration membrane can effectively suppress the diffusion of halogens from a positive electrode in a zinc-iodine battery / zinc-bromine battery, mitigating the problem of capacity loss of a zinc-iodine / zinc-bromine flow battery, and achieving long-term cyclic stability.
