Abstract

In this study, vertical nanowire arrays of MoO _3-x grown on metallic substrates with diameters of ∼90 nm show high-capacity retention of ∼630 mAhg ^-1 for up to 20 cycles at 50 mAg ^-1 current density. Particularly, they exhibit a capacity retention of ∼500 mAhg ^-1 in the voltage window of 0.7-0.1 V, much higher than the theoretical capacity of graphite. In addition, 10 nm Si-coated MoO _3-x nanowire arrays have shown a capacity retention of ∼780 mAhg ^-1, indicating that hybrid materials are the next generation materials for lithium ion batteries.
