摘　　要：综述了最近几年用氧化、复合技术改善锂离子电池负极材料性能的研究。采用氧化技术,石墨材料的表面结构改善,可逆容量增加,循环性能明显改善;直接制备使用纳米级氧化物,显示出可逆容量大及优良的循环性能和快速充放电能力。采用复合技术,可使碳材料、氧化物材料的结构、可逆容量、循环性能得到改善或提高。氧化技术和复合技术是进一步提高锂离子电池负极材料性能的有效方法。The recent studies to improve the properties of anode materials for lithium-ion battery are reviewed. The surface structure, reversible capacity and cycling behavior of graphite are improved considerably by oxidation; Nano-sized oxides exhibit the characteristics of big reversible capacity, good cycling performance and high rate capability. After utilization of composites technologies, the structure, reversible capacity and cycling performance of carbonaceous and oxides materials become better. It is shown that oxidation and composite technologies are effective ways to improve physical-chemical properties of anode material for lithium-ion batteries.
