摘　　要：以针状焦作为核心,外层包覆酚醛树脂的复合材料作为锂离子电池的负极材料,通过对比不同包覆量的复合材料的表面形貌、结构及其电化学性能的研究,得出结论:树脂对于针状焦具有较好的包覆作用,有利于锂离子的嵌入/脱出,改善了电化学性能。The composite material prepared by the needle coke coated phenol formaldhyde resin was used as cathode for lithium ion battery. According to research for the morphology ,structure ,and charge--discharge performance, the conclusion is drawn that the phenol formaldehyde resin show relatively good coat function for needle coke,which helps to improve insertion/deinsertion performance lithium ion of and enhance electrochemical performance.
