摘要：
A SiOx/C/graphene composite anode for lithium ion batteries with excellent electrochemical performance was prepared from SiO, SBR and graphene via the disproportionation treatment of SiO at high temperature, mechanical milling, spray drying and pyrolysis. The phase composition, morphology and electrochemical performance of the composites were detected by X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), energy disperse spectroscopy (EDS) and constant current charge-discharge test. The electrochemical test results revealed that the initial discharge capacity of pyrolytic SiOx/C/graphene composite anode material was 1 807 mAh/g. The reversible capacity reached 1 349 mAh/g and the Coulombic efficiency was 99.1% after 100 cycles, indicating a much higher cyclic stability compared to the SiOx/C and SiOx/C/graphene precursors, along with a good rate performance. © 2017, Materials Review Magazine.
