摘要
Abstract
A facile solvothermal approach has been developed to fabricate graphene-based MoS2 composite,which used PVP decorated graphene as the carrier and sodium molybdate and thiourea as the starting materials. The structure and morphology of the composite were characterized by field-emission scanning electron microscope(FESEM),transmission electron microscope(TEM), X-ray diffractometer(XRD)and X-ray photoelectron spectrum(XPS)respectively. Electrochemical performances of the material were also evaluated. The result demonstrated that the usage of graphene as substrate can prevent the aggregation of MoS2 sheets and thus lead to adequate contact between the active material and the electrolyte. MoS2/graphene composite manifests superior reversible specific capacity(about 800mA·h/g,50 cycles)and excellent rate capability as anode materials in lithium-ion batteries.关键词
