摘要
Abstract
Novel Si/C microsphere composites with different nano silicon contents were prepared by high-temperature pyrolysis.The obtained samples were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscope (TEM),constant current charging and discharging and cyclic voltammetry test.The results show that when the addition content of nano silicon is 8％,the first discharge capacity of Si/C composite microsphere anode material is 991 mAh/g at 100 mA/g;and after 100 cycles it remains a capacity of 321.8 mAh/g.The good perfromance was attributed to the high electric conductivity and relatively large surface areas of amorphous carbon.关键词
