摘      要：Aqueous Zn-iodine(Zn-I_(2))batteries have attracted extensive research interest as an emerging redox conversion energy storage system due to the low cost and high ***,the shuttling effects of polyiodides arising from incomplete redox conversion and inhomogeneous Zn plating on the Zn anode surface always hinder the commercial application of Zn-I_(2)*** this work,a two-birds-with-one-stone strategy is reported for long-life Zn-I_(2)*** on the strategy,the sulfonate-functionalized carbon fiber not only acts as the excellent iodine limiter to inhibit iodine species shuttling,but also as the uniform Zn plating guidance layer on the Zn anode surface to prevent the inhomogeneous deposition of Zn^(2+).Consequently,a superior cycling stability(a capacity of 124 mAh g^(-1)after 10,000 cycles at 5 A g^(-1))is *** calculations illustrate that sulfonate groups successfully induce charge redistribution on the carbon substrate,thereby strengthening the electronic interactions of the iodine species with the carbon *** charge-enriched sulfonate groups can guide the uniform deposition of Zn^(2+)through a strong Coulombic effect with Zn^(2+).This work gives a new perspective on the integrated design of cathodes and anodes for rechargeable batteries.
