Fe3O4/RGO复合材料的制备及其电化学性能研究
Synthesis of Fe3O4/RGO composites and their electrochemical performance
摘要
Abstract
With reduced graphene oxide (RGO) as the precursor, Fe3O4/RGO composites were synthesized via a hydrothermal method combined with annealing treatment;the crystalline phase, microstructure and component of Fe3O4/RGO composites were characterized by XRD, SEM, TEM and Raman spectra.As a new type of lithium battery electrode materials, their electrochemical performance and the corresponding performance enhanced mechanism were investigated by the CV and EIS tests.The results indicate that high loading Fe3O4/RGO anodes after charge-discharge 60 cycles show high reversible capacities of 709mAh/g at 200mA/g and 479mAh/g at 600mA/g, with a very good rate performance.Compared with the Fe3O4 electrodes, Fe3O4/RGO electrodes exhibit better electrochemical performance, which is associated with a synergy between the stable RGO matrix and its good conductivity;such a nano-sized configuration may not only facilitate the electron conduction but also help to maintain the structural integrity of active materials.关键词
