Silicon anode is considered as one of the most potential candidate materials for lithium ion batteries due to its high theoretical specific capacity and low lithium potential.However,the commercial application of silicon negative electrode is seriously hindered because of its poor conductivity and remarkable volume effect.Multi-wall carbon nanotubes (MWCNTs) with high electrical conductivity and mechanical strength were used to construct Si/CNT/C composites with 3D conductive network by a simple and easy-to-operate ball milling method.Base on a series of analyses,it indicated that the ball-milled nano-silicon in Si/CNT/C was evenly distributed,had a stable conductive network,and exhibited excellent electrochemical performance.Therefore,the Si/CNT/C prepared by this method had potential commercial applications.
