▎ 摘　　要

SrWO4/graphene composite was synthesized via a sol-gel method. The morphology and structure of the products were analyzed by SEM, TEM and XRD. The electrochemical performances of SrWO4/graphene composite were investigated by galvanostatic charge/discharge method, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results showed that the first cycle of the reversible specific capacity of SrWO4/graphene composite can reach to 575.9 mAh g(-1) at 50 mAg(-1). The charge/discharge cycling study indicates that the SrWO4/graphene composite was provided with excellent cycle performance and outstanding rate capability.
