A composite of reduced graphene oxide (r-GO) decorated densely with 20 nm Fe3O4 nanoparticles has been prepared by a facile solvothermal method. The Fe3O4/r-GO composites are used as the anode material for lithium ion batteries, which show an extremely high initial discharge specific capacity of 1702 mAh/g. Compared with the pure Fe3O4 nanoparticles, the composite anode exhibits a higher capacity retention capability since its specific capacity fades very slowly and retains a value of 711 mAh/g after 30 cycles. The r-GO sheets worked as an ultra-thin and conductive substrate can not only prevent the detachment and agglomeration of Fe3O4 nanoparticles, but also compensate for the volume change of Fe3O4 nanoparticles during the charge-discharge cycles, and thus extend the cycling life of the Fe3O4/r-GO composites electrode.

Silicon carbon nanoparticles (SCNPs) coated with reduced graphene oxide (rGO) were fabricated by a hydrothermal method and subsequently by a simple heat treatment process. SCNPs/rGO exhibit excellent electrochemical performance which not only attributes the rGO layer to inhibit the volumetric expansion of silicon and reduce the impedance between the active material and lithium ions during the electrochemical process, but also improves the electrical conductivity of SCNPs/rGO. The as-prepared compound was cyclically tested at a current density of 150[Formula: see text]mA/g, with the first charge and discharge capacities of 3152.2[Formula: see text]mAh/g and 3342.7[Formula: see text]mAh/g, respectively. Moreover, the electrochemical performance of SCNPs/rGO was better than SCNPs. The [Formula: see text] values for fresh battery, after 1 cycle and 100 cycles, are 120.9[Formula: see text][Formula: see text], 120.5[Formula: see text][Formula: see text] and 104[Formula: see text][Formula: see text]. Thus, compared with SCNPs, SCNPs/rGO exhibited lower overall impedance values. These results indicate that the addition of graphene layer significantly improved the electrochemical performance of SCNPs electrodes and reduced the internal resistance of the battery.
