Preparation method of indium-doped (002) zinc metal negative electrode

The invention discloses a preparation method of an indium-doped (002) texture zinc metal negative electrode, which comprises the following steps of: cleaning and drying a zinc sheet, then putting the zinc sheet into a roller press for cold rolling treatment to obtain a zinc sheet with a (002) texture, polishing the surface of the zinc sheet, putting the zinc sheet into an indium chloride solution for soaking, taking out the zinc sheet after the surface is polished, and cleaning and drying the zinc sheet. According to the method, the roller press is used for rolling the zinc foil to achieve the strong (002) texture, the obtained (002) texture zinc foil is placed in the indium chloride solution for replacement, rapid preparation of the indium-doped (002) texture zinc metal negative electrode is achieved, and compared with an existing method, the zinc metal negative electrode obtained through the method has the strong (002) texture and good hydrogen evolution inhibition and corrosion resistance, and can be used
