摘　　要：由于石墨作为负极材料的改性方法多种多样,所以重点探讨了什么样的方法更有效更可行。在论述各类改性方法的基础上,分析了其改性的内在原因,指出每种方法的不足之处;阐述了从中得到的一些启示;讨论了石墨选材对改性效果的影响;在对比所述各种方法后,认为掺杂或共改性是相对更好的改性途径。The methods for modification of graphite as negative electrode is very diverse. The more effective and more practicable methods are the focus of this article. The various means for modification of graphite anode were reviewed. Moreover, the enhancing of electrochemical performance was analyzed and the existing disadvantages were proposed; some illumination was exhibited; the influence on modification of different graphite materials were discussed; doping and co-modification were regarded as the much better approaches comparatively after comparing all of the methods above.
