The invention discloses a method for preparing conductive powder by recoating aluminum-doped nano zinc oxide with aluminum. The method comprises the following steps: firstly, preparing aluminum-doped zinc oxide powder; secondly, coating the aluminum-doped zinc oxide powder with an aluminum-containing film; finally, mixing the coated aluminum-doped zinc oxide powder with zinc powder, grinding, and calcining in an inert gas atmosphere to obtain the conductive powder. The method has the advantages that the zinc oxide conductive powder is prepared through primary aluminum doping and secondary aluminum coating, the primary aluminum doping improves the whiteness and the water dispersion of the nano zinc oxide and reduces the particle size of the nano zinc oxide, and the secondary aluminum coating further increases the defect concentration of zinc oxide crystals and improves the conductivity of the nano zinc oxide; the aluminum-doped zinc oxide is coated with a thin oxide film, so that zinc ions in water are unlikely to dissolve out, and the ball milling process of the zinc powder and the aluminum-doped zinc oxide is facilitated; the prepared conductive powder is high in conductive ability, small in particle size, light in color, wide in sources of raw materials, low in production cost, simple in preparation method, high in security, relatively light in environmental pollution, and suitable for industrial mass production.
