Tremella-like molybdenum dioxide consisting of nanosheets as an anode material for lithium ion battery

Tremella-like structured MoO2 consisting of nanosheets was obtained via a Fe2O3-assisted hydrothermal reduction of MoO3 in ethylenediamine aqueous solution. The as-prepared product was characterized and tested with scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV) and capacity measurement as anode material for lithium ion batteries. This structured MoO2 shows very high reversible capacity (>600 mA h g(-1)), good rate capability and cycling performance, presenting potential application as anode material for lithium ion batteries with high rate capability and high capacity.
