Abstract:

Graphene has always been regarded as a potential application material in the field of new energy conversion and storage industry because of its unique two-dimensional structure, large theoretical specific surface area, good carrier mobility, high Young's modulus and excellent thermal conductivity. These advantages make it possible to combine with one or more highly active inorganic/organic materials through covalent bond/non-covalent bond, and improve the defects of the materials themselves and optimize the performance of the materials through synergistic effects, thus expanding its application range. Therefore, how to design and synthesize graphene composite materials with certain functions and how to construct novel graphene structures to meet the requirements of energy and related fields for material-related properties have become one of the hotspots in the field of graphene materials. This article reviewed the design ideas of graphene-based composite materials in the fields of new energy conversion and storage industry. Then, it summarized the key issues of graphene-based composites in these various fields. Finally, the future trends and perspectives for the graphene in various fields were discussed.

Key words: graphene, composite, electrochemistry, catalyst, energy conversion and storage

摘要：

石墨烯具有独特的二维结构、较大的理论比表面积、高载流子迁移率、高杨氏模量以及高热导率等特性，一直以来被视为新能源转换与存储领域的潜在应用材料。这些优势使其可以与一种或多种高活性的无机/有机材料通过共价键/非共价键进行复合，并通过协同效应来改善材料自身的缺陷，实现材料的性能最优化，进而拓展了其应用范围。因此，如何设计并合成具有一定功能作用的石墨烯基复合材料，构筑新型石墨烯结构，满足能源及其相关领域对于材料相关性质的要求，成为石墨烯材料领域的研究热点方向之一。本文综述了近年来石墨烯基复合材料的设计思路及该类材料在新能源转换与存储领域上的应用现状，并对其在各领域存在的关键问题进行了总结。最后，对石墨烯在各领域今后的研究和发展方向进行了展望。
