石墨烯基材料的组装和电化学储能应用

石墨烯作为一种新型二维碳材料,因其独特的结构和优异性质受到广泛关注,在众多领域具有广阔的应用空间。然而由于石墨烯片层间存在较强的相互作用,在实际应用过程中极易发生团聚,从而造成片层利用率低以及性能的急剧降低。因此,利用石墨烯的二维基元结构特点,通过组装实现石墨烯片层的有序性搭接以提高其片层的利用率,对石墨烯材料的实际应用具有重要意义。本文归纳了近年来不断出现的石墨烯基材料的组装体及组装方法,重点介绍了不同形态石墨烯组装体的结构特点及其在电化学储能器件中的潜在应用。

Assembly and Electrochemical Energy Storage Applications of Graphene-Based Materials

Graphene has attracted extensive attentions due to its unique structure, excellent properties and great potential in various applications. However, due to the strong interaction among the two-dimensional sheets, the unavoidable aggregation of graphene results in low surface utilization, and thus, unsatisfied performance in practical applications. Graphene can be viewed as basic unit of carbon materials, and the surface utilization of graphene can be improved by assembling it into various graphene-based structures with ordered sheet arrangement, which is important to its practical applications in future. In this paper, we summary the different graphene-based assemblies and the corresponding methods reported in these years, and more importantly, the relations between the assembly structures and their usage in electrochemical energy storage applications are highlighted.
