This invention discloses a novel anion exchange resin for adsorbing perchlorate ions and its preparation method. The novel anion exchange resin is prepared using polyvinylbenzyl chloride, dioxane, and N,N-dimethylethanolamine. This resin improves the adsorption efficiency and effect for perchlorate ions, has a high regenerability, can resist interference from complex systems, and enhances the stability and service life of the resin.

The invention relates to the field of energy storage devices, in particular to a multifunctional aqueous zinc-iodine battery and an electrolyte thereof, and the multifunctional aqueous zinc-iodine battery comprises zinc ions and an electrolyte additive, the zinc ion source is zinc salt, and anions of the zinc salt are one or more of sulfate ions, acetate ions, nitrate ions, trifluoromethanesulfonate ions, perchlorate ions and the like; during working, the zinc-iodine battery is subjected to an I- / I2 / I + reversible oxidation-reduction reaction on the positive electrode side, and is subjected to Zn / Zn < 2 + > reversible dissolution / deposition on the negative electrode side. When Zn / Zn < 2 + > reversible dissolution / deposition occurs in the zinc negative electrode, through interaction of the electrolyte additive and Zn < 2 + >, crystal face growth of Zn metal (002) is promoted, hydrogen evolution reaction is inhibited, uniform deposition of zinc in the negative electrode is finally induced, and the cycle life of the negative electrode is prolonged. On one side of the positive electrode, the electrolyte additive interacts with other functional groups through a halogenated group to form a negative potential accumulation region, so that stable existence of I < + > ions is realized.
