Applications of graphene in the electrode materials of supercapacitors

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。

As its unique two-dimensional structure, graphenes have excellent conductivity and high surface area, and are regarded as one of the most potential electrode materials for supercapacitors. This article summarized the research progress of graphene-based supercapacitors, including modification of graphene and design special structure, compounding with pseudo-capacitance electrode materials （mainly metal oxides and conducting polymers）, compounding with other carbon materials. Lastly, the critical issues for high energy density supercapacitors and its commercial application were discussed.
