Abstract

The present invention relates to a method for preparing an anode active material and a secondary battery including the anode active material. The anode active material may be prepared by a method including the steps of: obtaining byproduct particles that have not been spheroidized in a step of pulverizing and spheroidizing flaky graphite particles; preparing coated particles by mixing the graphite byproduct particles with composite particles and performing a mechanochemical reaction thereon to coat the surface of the graphite byproduct particles with the composite particles; and spheroidizing the coated particles and coating the surface thereof with amorphous carbon to prepare spherical graphite.
