| 中文摘要: |
| Fe2O3锂离子电池负极材料因其具有的高能量密度而备受关注。但Fe2O3电极材料存在的如低导电性、充/放电过程中体积改变导致的循环稳定性差等问题限制其实际应用。介绍了高比表面积、结构稳定以及储锂动力学等因素对锂离子电池负极材料电化学性能的重要影响，综述电极活性材料纳米化、形貌控制和杂原子掺杂对Fe2O3负极材料电化学性能改善的相关研究进展，最后对Fe2O3电极材料的发展前景进行了展望。 |
| 英文摘要: |
| Fe2O3-based anode materials for lithium ion batteries (LIBs) have attracted much attention due to their high energy density. However, due to their low conductivity and poor cycle stability caused by volume change during charge/discharge process, the practical application of Fe2O3-based anode materials was still severely restricted. Thus, this review mainly discusses the relationship between the electrochemical properties for LIBs and the specific surface area, stable structure, Li-storage kinetics of anode materials. Afterwards, the effective methods to improve the electrochemical properties of Fe2O3-based anode materials were discussed and summarized, such as nanotechnology, structural design and heteroatom doping. At last, the prospects for Fe2O3-based anode materials in LIBs were discussed. |
