ANODE ACTIVE MATERIAL FOR RECHARGEABLE BATTERY, RECHARGEABLE BATTERY, AND METHOD FOR MANUFACTURING THE SAME

摘要

Disclosed is an anode active material for a rechargeable battery. The anode active material according to an embodiment of the present invention contains first spherical particles in which first particle precursors, which are scaly graphite fragments, are headed; and second particles that are dispersed between the scaly graphite fragments in the first particles. The second particles contain (i) at least one selected from a group consisting of SiOx, Si1-xMxOy, and a combination thereof; (ii) a combination of SiOx and Si; and (iii) at least one material selected from a group consisting of a combination of Si1-xMxOy and Si.
