Abstract
An anode active material for a lithium secondary battery includes a silicon-based active material that includes a core particle and a carbon coating formed over or on the core particle. The anode active material satisfies specific relation within a specific range. A lithium secondary battery includes an anode including the anode active material, and a cathode facing the anode.
