An embodiment of the present invention relates to a silicon-carbon composite, a manufacturing method thereof, and an anode active material for a lithium secondary battery comprising the same, and more specifically, the silicon-carbon composite of the present invention has a core-shell structure. A composite, wherein the core comprises silicon, a silicon oxide compound and magnesium silicate, and the shell comprises at least two carbon layers comprising a first carbon layer and a second carbon layer, wherein the second carbon layer Since silver is reduced graphene oxide, it is possible to improve the charge/discharge capacity, initial charge/discharge efficiency and capacity retention rate of the secondary battery when applied as an anode active material of a secondary battery. |
