Abstract

η-Fe ₂O ₃ composed of many sub-micrometer spindle-like particles has been successfully synthesized by a simple solvent-assisted precipitation route. The electrode of the as-obtained η-Fe ₂O ₃ powder shows a stable and ultrahigh reversible capacity of over 1200 mAh/g during up to 10 cycles at 100 mA/g and excellent rate capability, owing to the small and uniform grain size, mesoporous structure and advantageous crystallinity, which can be confirmed by SEM and TEM results. Based on the experimental results, it is believable that the η-Fe ₂O ₃ prepared by this method is a promising anode material for high energy-density lithium-ion batteries.
