Silicon/carbon (Si/C) composite anode materials are successfully synthesized by mechanical ball milling followed by pyrolysis method. The structure and morphology of the composite are characterized by X-ray diffraction and scanning electron microscopy and transmission electron microscope, respectively. The results show that the composite is composed of Si, flake graphite, and phenolic resin-pyrolyzed carbon, and Si and flake graphite are enwrapped by phenolic resin-pyrolyzed carbon, which can provide not only a good buffering matrix but also a conductive network. The Si/C composite also shows good electrochemical stability, in which the composite anode material exhibits a high initial charge capacity of 805.3 mAh g−1at 100 mA g−1and it can still deliver a high charge capacity of 791.7 mAh g−1when the current density increases to 500 mA g−1. The results indicate that it could be used as a promising anode material for lithium ion batteries.

A composite anode material of SnO2/graphite(GT)/carbon nanotube(CNT) for lithium-ion batteries was prepared by ball milling. It was observed that SnO2 particles were homogeneously embedded into the buffering matrix of graphite particles. This composite anode material showed an increased initial coulombic efficiencies of 56% in the first cycle, and after 25 charge–discharge cycles, a reversible capacity of 431 mAh/g was obtained, much higher than 282 mAh/g of SnO2/GT composite and 177 mAh/g of pure SnO2. The improvement in the electrochemical properties of the composite anode materials was mainly attributed to good electric conductivity of the CNT network and the excellent resiliency.
