We have developed a Si/graphene oxide electrode synthesized via ultrasonication-stirring method under alkaline condition. Scanning electron microscopy (SEM), transmission electron microscope (TEM), EDS dot-mapping and high-resolution transmission electron microscopy (HRTEM) results show that Si particles are evenly dispersed on the graphene oxide sheets. The electrochemical performance was investigated by galvanostatic charge/discharge tests at room temperature. The results revealed that Si/graphene oxide electrode exhibited a high reversible capacity of 2825mAh/g with a coulombic efficiency of 94.6% at 100mA/g after 15 cycles and a capacity retention of 70.8% after 105 cycles at 4000mA/g. These performance parameters show a great potential in the high-performance batteries application for portable electronics, electric vehicles and renewable energy storage.
