Synthesis and electrochemical properties of MoS 2 /NC composite as a novel anode for lithium battery

The MoS2/NC composite is synthesized successfully by electrospinning combined with calcination. The expected compounds are characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscope (TEM) techniques. The MoS2 and carbon doped with nitrogen (NC) are principal component in the composite (MoS2/NC). The composite took on morphology of nanofibers and exhibited outstanding electrochemical performances as novel anode material. The optimum synthesis conditions for the expected compounds were presented in this work. When load current density was 0.1 A g-1, the capacity of MoS2/NC composite can maintain as high capacity as 827 mAhg-1 after 200 cycles. When load current density was increased to 1 A g −1, its capacity can maintain as high as 554 mAhg−1 after 500 cycles. The MoS2/NC composite with typical morphology and composition not only owned high reversible capacity but also good rate performance, Therefore, it is promising anode material for lithium ion battery application.
