Zusammenfassung:Provided is an anode active material, including: an amorphous carbon material in which the ratio of moieties having a distance d002 of 3.77 Å or more between crystal planes is 4% to 15% based on the entire crystal plane distance distribution. When the anode active material is used, the lifespan characteristics of a lithium battery may be improved while exhibiting high capacity.
