Preparation and Performance of Si/Al/C Composites Anode Material Prepared by Glucose-Modified

Article Preview

Abstract:

Si/Al/C composites were synthesized by the method of doping aluminum and glucose-modified. The samples were characterized by XRD, SEM, and the capacity and cycling stability of the composites were tested by electrochemical charge/discharge test system. After glucose was pyrolyzed, the first discharge and charge capacity of Si/Al/C composites were 1312 and 956.7mAh/g, and the first coulombic efficiency was 72.9%. After 50 cycles, the capacity of Si/Al/C composites was 440mAh /g and the coulombic efficiency remained over 98.1%
