Abstract: 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 andmicrostructure of MoS₂ nanoparticles ,and the results shown that the MoS₂ pinterlayer distance reached 0.70 nm whichwas much larger than its bulk counterpart of 0.62 nm.MoS₂ nanoparticles exhibited excelent electrochemical performance as cathode materials for lithium-ion batteries.The first discharge capacity reached 1439mAh/g at thecurrent density of 100 mA/g.After 120 cycles,the reversible discharge specific capacity still maintained about 860 mAh/g.
