摘　　要：LiCoO2是目前商品锂离子电池中最广泛应用的正极材料,然而其价格昂贵且对环境有害,促使人们研究开发新型正极材料。由于Fe是地球上最丰富且无毒的金属,具有与LiCoO2相似岩盐结构的LiFeO2研究引起人们广泛关注。综述了LiFeO2基锂离子电池材料的研究进展,评述了制备与性能,展望了LiFeO2基锂离子电池材料未来的发展方向和应用前景。The use of environmentally friendly materials as electrodes for lithium ion batteries has become mandatory with a view to developing clean renewable technologies for the future.LiCoO2 was used as a positive electrode material at the early stages of the rocking-chair cell concept despite its high cost and toxicity,while this shortcoming fostered a research for alternative compounds based on other transition metals such as Fe,which is abundant in resource,less expensive and toxic than Co.With similar rock-salt structure to LiCoO2,LiFeO2 attracts great interests as potential alternatives to Li-Co-O positive electrodes.However,the use of LiFeO2 materials as electrodes is subject to major constraints arising from their low cycling efficiency,as well as also low operating voltage.The recent advances in LiFeO2-based cathode materials were summarized.The preparation and performance were reviewed.Finally,the current challenges were highlighted,and the focus of future research and development were proposed.
