摘　　要：未经处理的石墨毡作为电池电极可逆性差、电化学活性低,直接影响电池整体效率。文章主要对现有的几种碳毡进行筛选,并通过不同的改性方式处理碳毡,比较处理前后石墨毡电化学性能和组织形貌的改变,以期得到电化学性能优良的碳毡。The untreated graphite felt as the battery electrode has poor reversibility and low electrochemical activity, which directly affects the overall efficiency of the battery. In this paper, several existing carbon felts are selected and treated with different modification methods, the electrochemical properties and microstructure of graphite felt are compared before and after treatment, in order to obtain carbon felt with excellent electrochemical properties.
