Abstract
An interweaved silicon monoxide/graphite/carbon nanotubescarbon nanofibers SiO/G/CNTsCNFs composite has been easily synthesized by using highenergy wet ball milling spray drying in combination with a subsequent chemical vapor deposition method CNTsCNFs grow on the interface and the internal interspace of the spherical composite composed of SiO and graphite during the calcination process The existence of CNTsCNFs and graphite not only provides a buffer medium to accommodate the volume expansion of SiO during the electrochemical reaction process but also provides high electrical conductivity for electrode material When used as an anode material a reversible specific capacity is approximate 6723 mAh g−1 after 100 cycles at a current density of 100 mA g−1 which is about 18 times larger than that of the commercial graphite electrode 372 mA g−1 Due to the facile synthesis process of the composite and excellent performance of the asprepared electrode great commercial potential is envisionedThis work was financially supported by the National Science Foundation of China NSFC Nos 51201066 and 51171065 the Natural Science Foundation of Guangdong Province No S2012020010937 the Science and Technology Project Foundation of Zhongshan City of Guangdong Province of China no 20123A326 and the Scientific Research Foundation of Graduate School of South China Normal University Grant No 2014ssxm17
