One-pot synthesis of mixed-valence MoO sub(x) on carbon nanotube as an anode material for lithium ion batteries

A mixed-valence MoO sub(x)/carbon nanotube nanocomposite was synthesized using a one-pot microwave-assisted hydrothermal reaction in which 5 nm MoO sub( x) nanoparticles were coated on the surfaces of carbon nanotube. The MoO sub(x) nanoparticles in the nanocomposite had mixed Mo super(4+) and Mo su...

Description
Summary:A mixed-valence MoO sub(x)/carbon nanotube nanocomposite was synthesized using a one-pot microwave-assisted hydrothermal reaction in which 5 nm MoO sub( x) nanoparticles were coated on the surfaces of carbon nanotube. The MoO sub(x) nanoparticles in the nanocomposite had mixed Mo super(4+) and Mo super(6+) valence states. Thus, the nanocomposite showed a discharge behavior corresponding to both MoO sub(2) and MoO sub(3). The nanocomposite had a reversible discharge capacity of 900 mAh g super(-1) at a current density of 90 mA g super(-1), and could deliver discharge capacities of 770, 700, and 570 mAh g super(-1) at current densities of 450, 900, and 1800 mA g super(-1), respectively.
