摘要:
The carbon-coated MnO/C micro-nano composites were fabricated via precipitation, followed by thermal treatment, with Mn(CHCOO)(2)center dot H2O, ethylene glycol and oxalic acid dehydrate as the reactants, PVP, C6H12O6 and C6H4(OH)(2) as carbon source. The structure, morphology and electrochemical properties of the MnO/C materials Were characterized with X-ray diffraction, scanning electron microscope, transmission electron microscope and electrochemical experiments. The results indicate that the prepared MnO/C composite with a 3 nm carbon-coated layer may be a good anode material for lithium-ion battery. It shows an excellent cycling stability of 586 mAh/g after 50 cycles and excellent structural stability after several high-current charge and discharge courses.
