A facile 2-step method was realized to synthesize graphene-like layered structure MoS2 nanoparticles:producing Mo nanoparticles by the DC arc-discharge method and then reacting with S to obtain MoS2 nanoparticles.Various analytical methods including XRD,TEM and etc.were carried out to ascertain the morphology and microstructure of MoS2 nanoparticles,and the results shown that the MoS2 interlayer distance reached 0.70 nm which was much larger than its bulk counterpart of 0.62nm.MoS2 nanoparticles exhibited excellent electrochemical performance as cathode materials for lithium-ion batteries.The first discharge capacity reached 1439mAh/g at the current density of 100mA/g.After 120 cycles,the reversible discharge specific capacity still maintained about 860mAh/g.
