Fe2O3 xerogel used as the anode material for lithium ion batteries with excellent electrochemical performance

Abstract

A new strategy was applied to synthesise a porous nanostructure of α-Fe₂O₃ xerogel assembled from nanocrystalline particles (∼5 nm) with abundant mesopores (∼3 nm) using a hydrothermal method. The α-Fe₂O₃ xerogel exhibits excellent cycling performance (up to 1000 cycles) and rate capability (reversible discharging capacity 280 mAh g⁻¹ at 10 C) as a potential anode for high power lithium-ion batteries.
