The invention relates to the field of nanometer material preparation, in particular to a method for directly preparing nanometer silicon powder materials in the electrolytic refining process. The method comprises the steps that SiMe alloy with Si is used as an anode for electrolysis, and a cathode obtains electrolytic refining metal Me; anode mud produced through electrolysis is collected and acidized, after metal impurities are removed, deionized water is used for thorough cleaning, and therefore nanometer silicon powder with the particle size being 20-30 nm is obtained; and the SiMe alloy comprises, by mass, 0.5-13% of Si and the balance Me. Compared with an existing nanometer silicon preparing method, the method is low in cost, easy to operate and suitable for large-scale production.
