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 Ar atmosphere. Every sample was fabricated by controlling milling time, respectively. Their electrochemical characteristics as anode materials for lithium secondary batteries were investigated. Si particles are uniformly distributed throughout the nano-Si/graphite composite fabricated by ball milling. The fabricated nano-Si/graphite composite electrodes show improved cycle performance, but a large initial irreversible capacity.
