摘　　要：锂离子(Li^+)电池属于绿色环保电池,近年来已成为国际上研究的热点。α-Fe_2O_3理论电容量高(1007mAh/g)、储量丰富,具有代替传统石墨负极材料的潜力。其中纳米结构的α-Fe_2O_3可以有效地改善α-Fe_2O_3易团聚、体积易膨胀、电极易粉碎的问题。综述了近年来纳米结构α-Fe_2O_3及其复合材料在结构和电化学性能两方面的研究进展,并对其发展趋势进行了展望。As a kind of environmentally benign battery,lithium-ion batteries have become a research hotspot in the world in recent years, α-Fe2O3 with high theoretical specific capacity （1007mAh/g） and abundant reserves has great potential to replace the conventional graphite anode. Particularly, nanostructured a-Fe203 can effectively prevent the agglomeration, volume expansion and electrode pulverization of α-Fe2O3. Recent research progress of nanostructured α-Fe2O3 and its composites in the aspects of structures and electrochemical properties were reviewed. In addition, the development trends of materials were also prospected.
