Lithium-Ion Battery Anode Electrochemical Properties of Si/C Composites Using Graphite and Glucose as Carbon Source

Abstract:

Si/C composites were synthesized by using graphite and glucose as carbon source. The samples were characterized by X-ray diffractometer (XRD) and ﬁeld emission scanning electron microscope(SEM). The electrochemical charge/discharge test was used to evaluate capacity and cycling stability of the composites. The first discharge and charge capacity of SGC composite using graphite and glucose as carbon source were 1661mAh/g and 1259.1 mAh/g, and the first coulombic efficiency was 75.8%. After 20 cycles, the capacity of SGC composite was 380 mAh/g and the coulombic efficiency remained over 98%.
