The invention provides a preparation method of a rod-like powder electrode material, which comprises the following steps: S1, simultaneously adding a palladium precursor material and a mercury precursor material into an organic solvent, adding a reducing agent, uniformly stirring at normal temperature, and reacting at high temperature and high pressure; and S2, after the reaction is completed, cooling at room temperature, carrying out centrifugal separation, washing and re-centrifugal separation on a product to obtain a black substance, and drying the black substance to obtain a powder electrode material with a black rod-like morphology. According to the method, the heavy metal element mercury is successfully introduced into the palladium-based electrode material, modification of the precious metal element palladium and resource utilization of the heavy metal element mercury are achieved, operation is easy, implementation is easy, and the prepared rod-shaped powder electrode material has ...
