Research Progress of Fe2O3 in Lithium ion Batteries Anode Materials

Recently, lithium-ion batteries are widely used for portable electronic devices and mobile phones and show great potential for more demanding applications such as electric vehicles. As the anode materials of lithium-ion battery, Fe₂O₃ is one of the most likely transition metal oxides to replace graphite. Because it displays high theoretical capacity (1 007 mA·h·g⁻¹), abundant reserves, good safety performance, non-toxicity, friendly to environment and low cost, it has been widely used in gas sensors, catalysis, information storage and energy storage and so on, and is a kind of great potential electrode material. The basic structure and working principle of lithium-ion battery is introduced. The lithium storage mechanism and preparation method of Fe₂O₃ is reviewed. The research progress of Fe₂O₃ and its composites used as anode materials of lithium-ion battery in recent years is summarized.
