  "textContent": "The present invention relates to an anode active material for lithium secondary batteries and a method for manufacturing same, the anode active material comprising: a core part including a carbon-silicon complex and having a cavity therein; and a coated layer which is formed on the surface of the core part and includes a phosphor-based alloy. The anode active material of the present invention, including the phosphor-based alloy coated layer formed on the surface of the carbon-silicon complex having the cavity therein, enables stress resulting from a volume expansion caused by the alloying of lithium and Si to be released by coating the surface of an Si-based active material with a phosphor-based alloy. Also, the manufacturing method for the anode active material according to the present invention enables easy adjustment of the thickness of the coated layer.",
