Abstract

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.
