A MoS2/graphene composite was synthesized at 240 degrees C by a hydrothermal method using graphene oxide, Na2MoO4 and CS (NH2)(2) as the raw materials. Results indicate that the spherical flower-like MoS2 structure was self-assembled by thin MoS2 micrometer size layers and dispersed uniformly on the surface of graphene. The MoS2/graphene composite as an anode material retains a capacity of 735. 2 mAli/g after 100 cycles under a current density of 100 mA/g and has a good rate performance (490.3 mAh/g at 400 mA/g and 411.9 mAh/g at 800 mA/g). The excellent electrochemical performance of the composite is attributed to its special structure. The thin MoS2, layers shorten the diffusion and transport paths for Li+ ions and electrons. The abundant mesopores are beneficial for ion diffusion and act as a buffer to inhibit volume changes during charge-discharge. Graphene increases the charge-discharge rate of MoS2 effectively owing to its high conductivity and high surface area.
