  "textContent": "An anode active material for a secondary battery according to an embodiment of the present invention includes a plurality of a composite particle. The composite particle includes a carbon-based particle containing pores therein, a silicon-containing coating layer formed at an inside of the pores and/or on a surface of the carbon-based particle, and a surface oxide layer formed on the silicon-containing coating layer. The surface oxide layer contains silicon oxide. A silicon oxidation number ratio defined by Equation 1 of the composite particle is 0.6 or less.",
