Abstract:

The tremendous volume change, the low conductivity and the aggregation of MoS2 lead to its unsatisfactory electrochemical performance. To overcome these disadvantages, hierarchical MoS2/C grown on reduced graphene oxide (MoS2/C@RGO) nanosheets were fabricated by a simple hydrothermal route in this work. By insertion of semigraphitized carbon, the interlayer spacing of MoS2 is increased, and the MoS2 nanosheets vertically adhere to RGO, leading to the formation of a three-dimensional conductive network for electron transfer and ion diffusion. Consequently, MoS2/C@RGO exhibits excellent rate performance and cycling stability as anode material for sodium-ion batteries, and delivers a reversible capacity up to 257 mA h g(-1) at 1 A g(-1) after 300 cycles with approximately 91% capacity retention.
