Preparation process of zinc negative electrode based on molybdenum disulfide modification

The invention belongs to the field of aqueous ion batteries, particularly relates to a preparation process of a zinc negative electrode based on molybdenum disulfide modification, and aims to solve the problems of hydrogen evolution, passivation and dendritic crystals possibly occurring in a bare zinc negative electrode in an existing water battery system, the invention provides the following scheme: the preparation process comprises the following steps: S1, preparation of an electro-deposition solution: weighing sodium perchlorate, adding a molybdenum disulfide solution, and uniformly stirring; according to the preparation method disclosed by the invention, the content and morphology of MoS2 on the surface of the zinc sheet can be controlled, the corrosion phenomenon on the surface of the negative electrode sheet can be relieved, zinc ions are effectively guided to deposit and fall off, and the generation of zinc dendrites is inhibited, so that the electrochemical performance is improved, and relatively good
