This paper reports the synthesis MoS2/graphene composite as an anode using commercial graphene as conductive enhancer and structural modifier. X-ray powder diffraction (XRD) and morphology details show that the as-synthesized MoS2/graphene composite has hexagonal structure and shows three-dimensional hierarchical network structure. The anode electrochemical properties of MoS2/graphene composite and pure MoS2 were measured and analyzed by galvanostatic charge-discharge cycling vs. Na/Na+ at different current densities in 0.05-3.0 V. Compared to pure MoS2, MoS2/graphene composite demonstrates great specific capacity (509 mAh g(-1) at the current rate about 0.3 C), excellent rate capability (305 mAh g(-1) at the maximum current rate 5 C) and relatively good cycle-life (capacity reached 84% after 100 cycles). Moreover, the facile synthesis strategy of MoS2/graphene can provide a reference for designing other transition metal chalcogenides composites containing graphene for high performance SIBs.
