Disclosed are a zinc powder anode material, a preparation method therefor, and a zinc-ion battery, which relate to the technical field of batteries. The preparation method for a zinc powder anode material includes the following steps: providing zinc powder and a conductive material; dispersing zinc powder and a conductive material in a solvent to obtain a mixed solution; performing ball milling of the mixed solution; transferring the ball-milled mixed solution to a sealed container, heating same to a target temperature, stopping heating, introducing carbon dioxide into the sealed container, stopping introducing carbon dioxide when a pressure in the sealed container reaches a target pressure, and leaving same to stand for preset time, where carbon dioxide reaches a supercritical state at the target pressure and the target temperature; and sequentially performing depressurizing, cooling, coating, and drying to obtain a zinc powder anode material.
