SILICON-BASED CARBON COMPOSITE, PREPARATION METHOD THEREFOR, AND ANODE ACTIVE MATERIAL COMPRISING SAME
An embodiment of the present invention relates to a silicon-based carbon composite, a preparation method therefor, and an anode active material for a lithium secondary battery, comprising same, and, more specifically, the silicon-based carbon composite of the present invention is a silicon-based carbon composite having a core-shell structure, wherein the core comprises silicon, silicon oxide compound and magnesium silicate, the shell comprises at least two carbon layers comprising a first carbon layer and a second carbon layer, and the second carbon layer is reduced graphene oxide, and thus, during application of the silicon-based carbon composite to an anode active material for a secondary battery, the charge/discharge capacity, initial charge/discharge efficiency and capacity retention of the secondary battery can be improved.
