Synthesis and characterization of MnO/C micro-nano composites

Abstract:

The carbon-coated MnO/C micro-nano composites were fabricated via precipitation, followed by thermal treatment, with Mn(CHCOO)2?H2O, Ethylene glycol and Oxalic acid dehydrate as the reactants, PVP, C6H12O6 and C6H4(OH)2 as carbon. The structure, Morphology and electrochemical properties of the MnO/C materials were characterized with X-ray diffraction, scanning electro microscope, transmission electro microscope and electrochemical experiments. The results indicate that the MnO/C composite with a 3nm carbon-coated layer may be a good anode material for lithium-ion battery. It shows an excellent cycling stability of 586.1mAh/g after 50 cycles and excellent structural stability after several high-current charge and discharge courses.
