Abstract
An anode active material for a lithium secondary battery having high-capacity and high-efficient charge/discharge characteristics. The anode active material includes silicon single phases; and silicon-metal alloy phases surrounding the silicon single phases. A dopant is distributed in the anode active material, and the silicon single phases are formed through rapid-cooling solidification, and the silicon single phases have a fine microstructure due to the dopant.
