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.

采用复合溶胶-凝胶法结合后续热处理，制备了具有包埋结构的氧化亚硅/碳（SiOx/C）复合负极材料。扫描电子显微镜分析结果表明：氧化亚硅纳米颗粒嵌入在无定形碳中。电化学性能测试表明：SiOx/C复合材料具有较高的比容量、优异的循环稳定性和倍率性能。材料在0.1 A/g的电流密度下100次循环后的可逆比容量为710 mA·h/g，容量几乎无衰减；在1.6 A/g的电流密度下，可逆比容量为380 mA·h/g。优异的电化学性能是由于材料的包埋结构能有效地缓冲SiOx充放电过程中的体积膨胀，保证材料的结构完整性和电化学循环稳定性。

摘要
收起

采用复合溶胶-凝胶法结合后续热处理，制备了具有包埋结构的氧化亚硅/碳（SiOx/C）复合负极材料。扫描电子显微镜分析结果表明：氧化亚硅纳米颗粒嵌入在无定形碳中。电化学性能测试表明：SiOx/C复合材料具有较高的比容量、优异的循环稳定性和倍率性能。材料在0.1 A/g的电流密度下100次循环后的可逆比容量为710 mA·h/g，容量几乎无衰减；在1.6 A/g的电流密度下，可逆比容量为380 mA·h/g。优异的电化学性能是由于材料的包埋结构能有效地缓冲SiOx充放电过程中的体积膨胀，保证材料的结构完整性和电化学循环稳定性。

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.
