Single-walled carbon nanohorns coated with Fe2O3 as a superior anode material for lithium ion batteries

A novel composite of Fe2O3 and single-walled carbon nanohorns (SWCNHs) was firstly developed via a simple hydrothermal method. As an anode material for lithium ion batteries, a Fe2O3/SWCNHs composite shows excellent rate performance and cycle stability, even at a high current density of 1000 mA g(-1).
