摘    要:将9,10-蒽醌(AQ)通过升华法填充在介孔炭(MC)的孔中,制备出蒽醌/介孔炭寄生型复合物。用TG/DSC、SEM、氮吸附等方法对介孔炭及复合材料进行了表征,应用恒流充放电、循环伏安法、交流阻抗等测试手段对复合材料的电化学性能进行了测试。结果表明炭/醌复合电极的比容量和循环性能较蒽醌电极有了很大程度的提高。其中蒽醌填充量为75%的复合材料首次放电比容量达到216mAh/g,50次循环之后,比容量仍有76mAh/g,是蒽醌电极比容量的2倍。

关 键 词:介孔炭  寄生复合材料  有机物正极材料  电化学性能

Abstract:The mesoporous carbon(MC)/AQ parasitic composite was synthesized by filling 9,10-anthraquinone into pores of MC with sublimation.The composite was charactered by the methods of TDA/DSC,SEM and N2 adsorption.The electrochemical performance of the composite was investigated by the methods of galvanostatic discharge/charge and cyclic voltammetry.The results indicated that the specific capacity and cycle life of the composite was increased.The initial discharge specific capacity of the composite(75% AQ containe...
Keywords:mesoporous carbon  MC/AQ parasitic composite  organic cathode materials  electrochemical performance
