Summary:Disclosed are a carbon-coated silicon oxide powder for an anode material of a secondary battery, and a manufacturing method thereof. The manufacturing method of the present invention comprises: a first step of forming a porous material by mixing silicon chloride and glycol, a divalent alcohol; a second step of forming silicon oxide by heat-processing the porous material in an inert gas atmosphere; a third step of forming a liquid composite by mixing silicon oxide formed at the second step and hexane; and a fourth step of forming carbon-coated silicon oxide by heat-processing the liquid composite in an inert gas atmosphere. Here, when the silicon oxide is represented in a general formula, SiOx, the content of oxygen (x) is in a range of 0<x<2.
