摘要

High-performance materials are the key to developing new alternative energy-storage systems[1-4].Sodium ion batteries(SIBs)are regarded as the promising large-scale electric energy storage owing to the high abundance and low cost of sodium resources[1,5-9].However,the sluggish kinetics of Na+caused by the large-sized Na+(1.02 ?)result in the lower energy density and unsatisfactory electrochemical properties[10-14].Till now,anode materials used for SIBs include carbonaceous materials,titanium-based materials,metallic alloys,metal sulfides and tran-sition metal oxides[15-24].Among them,transition metal oxides have gained extensive attention due to the high theoretical capac-ity[25].In particular,FeOx based materials are widely explored in SIBs owing to their abundant resource,low cost and environment-friendly nature[26-28].
