Preparation and application of hydrated molybdenum oxide modified composite zinc negative electrode

The invention belongs to the field of aqueous ion batteries, and particularly relates to preparation and application of a hydrated molybdenum oxide modified composite zinc negative electrode, a preparation method of the hydrated molybdenum oxide modified composite zinc negative electrode comprises the following steps: S1, preparing an electro-deposition solution, weighing ammonium molybdate into a volumetric flask, and fixing the volume by using water as a solvent for later use; s2, a zinc sheet substrate is prepared, specifically, a metal zinc sheet is cut into zinc sheets with the same size, the surfaces of the zinc sheets are cleaned with deionized water and ethyl alcohol in sequence, drying is conducted for ten minutes under vacuum, and it is guaranteed that the deposition area is consistent; the thickness of hydrated molybdenum oxide formed on the surface of a zinc sheet is controlled through the deposition time, an amorphous hydrated molybdenum oxide modification layer is formed on the surface of zinc,
