中文摘要：
核壳结构材料可以实现核与壳功能的复合与互补，近年来核壳结构的设计理念也被引入到锂离子电池材料中。本文综述了纳米，亚微米核壳结构锂离子电池材料的制备方法、电化学性能和结构稳定性等方面的最新研究进展，评述了该类材料存在的问题并展望了其发展前景。商业化的锂离子电池材料还不能满足高能量密度和安全性等多方面的要求，通过合成核与壳功能互补的材料，可望提高材料的综合性能。
英文摘要：
Materials with core-shell structures can combine the functions of both core and shell parts. In recent years, the material design concept of core-shell structures has also been introduced to the field of lithium ion batteries. Recent progress is reviewed on the preparation, electrochemical performances, and structural stability of core-shell structured cathode and anode materials in lithium ion batteries, and problems and prospect are also pointed out for this kind of materials. Since the current commercial lithium ion battery materials can＇t satisfy the requirements such as highenergy density and reliable safety, preparing core-shell materials is hopeful to increase the general performances of lithium ion battery materials.
