摘　　要：针状焦由于具有价格低廉、来源广泛、石墨化后电性能好等优点,已经在锂离子电池负极材料中得到了广泛的应用。为改善由针状焦合成的人造石墨在锂离子电池中与电解液的相容性,提高其循环寿命,以酚醛树脂为包覆剂对针状焦进行了包覆改性,再进过碳化、石墨化制备得到了包覆改性人造石墨负极材料。研究了其电化学性能,确定了最佳的包覆量。Needle coke was used widely in the anode materials of lithium ion battery due to the merits of low cost, rich sources and good performance after graphitization. To improve the cycle performance and compatibility of anode material in lithium ion battery, the needle coke was coated with PF resin. After carbonization and graphitization, the coating- artificial graphite anode material was prepared. Its electrochemical performance was studied and the optimum coating amount was determined.
