A SiOx/C composite with an embedded-structure was prepared by a dual sol-gel one-pot method and subsequent heat treatment. Based on the analysis by scanning electron microscopy, SiOx nanoparticles are fully embedded in an amorphous carbon matrix. The results by electrochemical test indicate that as anode material for Li-ion battery, the optimized SiOx/C composite demonstrates a high specific capacity, an excellent cyclic performance and a rate capability. A reversible specific capacity of 710 mA·h/g is achieved without an obvious decline of the capacity for 100 cycles at a current density of 0.1 A/g, and a specific capacity is 380 mA·h/g at a current density of 1.6 A/g. The excellent electrochemical performance is attributed to the well-designed embedded-structure, which can effectively accommodate the volume variation of SiOx during charge/discharge process and therefore ensure the structural integrity and cyclic stability of SiOx/C electrode.
