摘　　要：导电剂在锂离子电池活性材料中只添加很少一部分比例,但其重要性却不可忽视,每种不同的电极活性材料都有其匹配的导电剂。导电剂的材料、形貌、粒径及含量对电池都有着不同的影响,碳系导电剂从类型上可以分为导电石墨、导电炭黑、导电碳纤维和石墨烯。总结了以上四种类型的碳系导电剂近年来的研究进展,提出了碳系导电剂在选用时应注意的事项,并展望了复合导电剂、碳纳米管及石墨烯的应用前景。Only a small portion of conductive agent is added in the active material of lithium ion batteries, but its importance can not be ignored, and each electrode active materials matches a conductive agent. The material, morphology, particle size and content of the conductive agent have different effects on the battery. The carbon-based conductive agent can be classified into conductive graphite, conductive carbon black, conductive carbon fiber and graphene. This paper summarized the research progress of the above four types of conductive agents in recent years, and put forward the matters of carbon-based conductive agent in the selection, and prospected the application of the composite conductive agent, carbon nanotubes and graphene.
