英文摘要	首次采用介质阻挡放电等离子体辅助高能两次球磨制得Si-C复合材料，其结构为微纳尺度硅颗粒均匀分散于微米级碳基体上. Si-C复合电极首周期循环放电容量为1259 mAh·g-1，20和100周期循环的容量分别为474和396 mAh·g-1. 该电极充放电曲线和交流阻抗测试的结果表明，复合材料中的硅和碳均参与锂离子嵌/脱反应，且其电荷传导阻抗明显低于纯Si.; Silicon-carbon (Si-C) composites, with microstructure of multi-scaled Si particles being homogenously dispersed in micro-sized carbon matrix, had been prepared by dielectric barrier discharge plasma assisted two-step milling for the first time. The Si-C composite anode had a discharge capacity of 1259 mAh·g-1 at the first cycle, while the capacity retained 474 and 396 mAh·g-1 after 20 and 100 cycles, respectively. Charge-discharge curves and AC impedance response indicated that both silicon and carbon phases in the composite anode were involved during the lithiation/delithiation reactions and the electron transport resistance in the Si-C composite anode was much lower than that in the pure Si anode.; 国家自然科学基金项目（No. 51201065, No. 51231003）、中央高校基本科研业务费专项资金（No. 2012ZM0001）和广东省自然科学基金博士科研启动项目（No. S2012040008050）资助; 作者联系地址：华南理工大学材料科学与工程学院，先进储能材料广东省重点实验室，广东广州 510641; Author's Address: School of Materials Science and Engineering, South China University of Technology，Guangdong Key Lab of Advanced Materials for Energy Storage, Guangzhou 510640, China; 通讯作者E-mail：memzhu@scut.edu.cn
