description The invention discloses a novel multifunctional aqueous zinc ion battery electrolyte and a preparation method and application thereof, the aqueous zinc ion battery electrolyte takes diethylenetriamine pentaacetic acid as an electrolyte additive, a zinc negative electrode can be protected, and the electrochemical performance of an aqueous zinc ion battery is improved. The diethylenetriaminepentaacetic acid serving as a chelating agent can be chelated with zinc, guide uniform zinc flux and promote desolvation of zinc ions, and the diethylenetriaminepentaacetic acid is rich in carboxyl and can be preferentially adsorbed on the surface of zinc metal, so that direct contact between water and the zinc metal is blocked, and water-related side reactions, including hydrogen evolution, corrosion and the like, of the diethylenetriaminepentaacetic acid are inhibited. In addition, the diethylenetriamine additive can stabilize the pH value in the battery, reduce the generation of byproducts and improve the cycling stabilit
