Abstract

Atomic layer deposition (ALD) of TiO₂ shells on MoO₃ nanobelts (denote as TiO₂@MoO₃) is realized using a home-made ALD system, which allows a controllable hydrolysis reaction of TiCl₄–H₂O on an atomic scale. When used as an anode material for lithium ion batteries, the TiO₂@MoO₃ electrode demonstrates much enhanced lithium storage performance including higher specific capacity, better cycling stability and rate capability.
