In this work, to avoid volume expansion of silicon during intercalation/ de-intercalation of lithium we coated pitch on silicon particle. Carbon/silicon composites were synthesized by mixing silicon powders with petroleum pitch and subsequent heat treatment. Also, we used carbon black as conductive material to improve electrical conductive. The physical characteristics of the synthesized composites were analyzed by SEM and XRD. In addition, their electrochemical properties were examined by the electrochemical analysis techniques such as charge/discharge performance, cyclic voltammetry. |
