Abstract
Provided are an anode active material including carbon-based particles, silicon nanowires grown on the carbon-based particles, and a carbon coating layer on surfaces of the carbon-based particles and the silicon nanowires, and a method of preparing the anode active material. Since the anode active material of the present invention is used in a lithium secondary battery, physical bonding force between the carbon-based particles and the silicon nanowires may not only be increased but conductivity may also be improved. Thus, lifetime characteristics of the battery may be improved.
