In the present study, a molybdenum disulfide MoS₂ nanosheets (MoS₂ NSs) were synthesized via a lithium intercalation and exfoliation method. The morphology and structure of the as-prepared MoS₂ was characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and Raman spectrometer. The MoS₂ NSs electrode exhibited higher specific capacitance (148 Fg^-1 at 1 mVs^-1 or 142 Fg^-1 at 1 Ag^-1) with excellent cycling stability, compared with bulk MoS₂. The result shows that MoS₂ is a promising electrode material for electrochemical supercapacitor.
