Single-walled carbon nanohorns coated with Fe_2O_3 as a superior anode material for lithium ion batteries

摘要

A novel composite of Fe_2O, and single-walled carbon nanohorns (SWCNHs) was firstly developed via a simple hydrothermal method. As an anode material for lithium ion batteries, a Fe_2O_3/ SWCNHs composite shows excellent rate performance and cycle stability, even at a high current density of 1000 mA g~-1.
