氧化还原石墨烯支撑的硫化锰负极材料
MnS anode material supported on rGO
摘要
Abstract
The rGO supported MnS electrode was designed based on physicochemical merits of rGO via a facile solvothermal procedure. The crystal structure and micromorphology of MnS/rGO material were investigated by XRD and SEM measurements, and also evaluating its electrochemical properties. The MnS/rGO electrode manifests excellent cycling stability (614.1 mAh/g remaining after 200 cycles at 1.0 A/g) and good rate capability (average discharge capacity of 142 mAh/g at 10.0 A/g). The outstanding electrical conductivity and mechanical toughness of rGO were beneficial for the MnS/rGO composites in terms of enhancing the surface electrochemical oxidation kinetics of Mn2+ to Mn3+, mitigating the volume change in the process of cycling and improving the structure stability, which endowing salient electrochemical performances. The unique advantages of MnS/rGO anodes might open an avenue for conceiving new generation lithium-ion batteries.关键词
