A mixed-valence MoO x /carbon nanotube nanocomposite was synthesized using a one-pot microwave-assisted hydrothermal reaction in which 5 nm MoO x nanoparticles were coated on the surfaces of carbon nanotube. The MoO x nanoparticles in the nanocomposite had mixed Mo4+ and Mo6+ valence states. Thus, the nanocomposite showed a discharge behavior corresponding to both MoO2 and MoO 3. The nanocomposite had a reversible discharge capacity of 900 mAh g-1 at a current density of 90 mA g-1, and could deliver discharge capacities of 770, 700, and 570 mAh g-1 at current densities of 450, 900, and 1800 mA g-1, respectively.
