Fabrication of β-MnO2/RGO composite and its electrochemical properties

Abstract

MnO2 is considered to be a promising alternative anode material for lithium ion batteries. In this work, β-MnO2/RGO composite has been successfully fabricated via hydrothermal method. The sample is carefully investigated by X-ray diffraction (XRD) techniques, Raman spectra, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). When β-MnO2/RGO composite as anode material for lithium ion batteries, which shows good cycling performance and excellent rate capacity.
