In a word, the SGC series composites anode were successfully synthesized by a FTCVD way in a FTCVD device. EDX elemental mapping and cross section SEM image of SGC granule indicates that the SGC is made up of homogeneous distribution of oxygen, carbon and silicon elements and the carbon is focusing on the external of SiO particles, which indicates that the granules are uniformly coated with carbon layer. Electrochemical tests show that the SGC-37 present a good cycle stability and rate

A series SiO/[email protected] (SGC) composites electrode are successfully prepared by a fluidization thermal chemical vapor deposition (FTCVD) route in a kilogram-scale fluidized bed CVD equipment. This strategy can avoid the effect of particle agglomeration on carbon coating during heating reaction. The phase composition, element distribution, particle appearance and electrochemical properties of the as-obtained SGC composite is investigated in detail. The charge specific capacity of SGC-37 is close to 799.1 mAh g−1 after 100 cycles at 200 m...
