Abstract
Disclosed herein is a non-carbon-based anode active material for lithium secondary batteries, including: a core containing silicon (Si); and silicon nanoparticles formed on the surface of the core. The non-carbon-based anode active material is advantageous in that the increase in the volume expansion during charging-discharging can be prevented by the application of silicon nanoparticles, and in that SiOx(x<1.0) can be easily prepared.
