Abstract:
Provided are a carbon-silicon composite having improved capacity and cycle stability, and a method of preparing the same. More particularly, the present invention relates to a carbon-silicon composite, in which surfaces of silicon particles are coated with a carbon-based material that is doped with at least one type of doping atoms selected from the group consisting of nitrogen (N), phosphorous (P), boron (B), sodium (Na), and aluminum (Al), and a method of preparing the same.
