石墨烯由于其独特的二维结构和优异的物理性质,如高电导率、高比表面积等,是目前最具潜力的超级电容器的电极材料之一。本文综述了石墨烯作为超级电容器电极材料的研究进展,包括石墨烯的改性与结构设计、石墨烯与赝电容电极材料复合(如金属氧化物和导电聚合物)、石墨烯与其他炭材料复合等。并对石墨烯应用到超级电容器电极材料中存在的问题展开了讨论。
Due to its unique two-dimensional structure and excellent physical properties, such as high conductivity and high specific surface area, graphene is one of the most promising electrode materials for supercapacitors. In this paper, the progress of graphene as an electrode material of supercapacitor is reviewed, including the modification and structural design of graphene, the combination of graphene and pseudocapacitive electrode materials (such as metal oxides and conductive polymers), graphene and other carbon materials Wait. The problems of applying graphene to the electrode material of supercapacitor are also discussed.
