The invention belongs to the technical field of water-based zinc batteries, and discloses a zinc metal negative electrode material, a preparation method thereof and application of the zinc metal negative electrode material in water-based zinc batteries. The method comprises the following steps: dispersing an ion conductor with an ion conducting effect, an electron conductor with an electron conducting effect and zinc powder in an organic solvent, stirring to form slurry, pouring the slurry on a polytetrafluoroethylene mold, and volatilizing the organic solvent to obtain the zinc metal negative electrode material. The process is simple and convenient, the operability is high, the pouring area and thickness of the material are easy to control, and mass production is easy. The material can effectively block air and water, so that the zinc metal negative electrode is effectively protected. The material has excellent mechanical flexibility and can meet the application requirements of flexible wearable batteries. T
