摘　　要：对可作为锂离子电池负极材料的重庆石墨试样（CX）的电化学性能进行了比较详细的研究。为了改善 CX在大电流条件下的充放电性能,尝试在CX石墨表面采用次磷酸钠碱性化学镀镍。讨论了不同浓度镀液对镀镍石墨嵌锂性能的影响。实验发现,在大电流条件下,镀镍石墨CXNi1的嵌锂性能和循环性能最好。The electrochemical performances of graphite from Chongqing named CX used as Li-ion battery anode material were studied in details, In order to improve the electrochemical performances of CX at higher current density, nickel plating were tried on it by electroless plating method. Besides, the effects of different plating concentrations on the intercalation and deintercalation of lithium ion were discussed. At higher current density, the chemical nickel-coated graphite by scheme is much better than the others in electrochemical performances and cycle life.
