Recently, Si/Carbon composite have been suggested as a promising anode material for lithium batteries. In this study, nano-Si/graphite composites are fabricated by a ball milling method in Oxygen atmosphere. Every sample was fabricated by controlling milling time, respectively. Their electrochemical characteristics as anode materials for lithium secondary batteries were investigated. Mechanically induced oxidation on the surface is responsible for suppressing the fracture rate and preserving the crystallinity of natural graphite milled in Oxygen atmosphere
