A high capacity MnFe2O4/rGO nanocomposite for Li and Na-ion battery applicationsElectronic supplementary information (ESI) available: TGA, CV and cyclic stability for pure MnFe2O4. See DOI: 10.1039/c5ra11439j
A porous MnFe 2 O 4 /reduced graphene oxide (rGO) nanocomposite with high storage capacity was prepared by a hydrothermal method. The MnFe 2 O 4 /rGO nanocomposite sample was characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy and high resolution transmission electro...
