摘要
石墨烯及复合材料具有比表面积大、电导率高、导热性能和力学性能良好等优点,在电极材料、传感器、储氢材料等领域具有广泛的应用。但以高碳含量的天然资源煤为前体制备煤基石墨烯及复合材料达到煤炭清洁高效利用的研究目前报道有限,尤其是将其作为电极材料应用到储能领域的研究较少。本文重点总结了以不同煤质及衍生物为原料构建不同形貌和结构的煤基石墨烯及复合材料的方法以及存在的问题,详细介绍了煤基石墨烯及复合材料在储能领域,尤其是超级电容器、锂离子电池及钠离子电池领域的应用研究现状,最后提出了当前煤基石墨烯及复合材料的主要研究方向。该综述旨在为煤基新型石墨烯及复合材料的制备开发以及在储能领域的应用提供一定的思路。
Graphene and its composites have been widely studied and applied in electrode materials,sensors, hydrogen storage materials and other fields due to their advantages of large specific surface area,high electrical conductivity, good thermal conductivity and mechanical properties. However, there are limited reports on the preparation of coal-based graphene and composite materials with high carbon content of natural resources as precursors to achieve clean and efficient utilization of coal, especially the research on its application as electrode materials in the field of energy storage. In this paper, the methods and problems of coal-based graphene and its composites with different morphologies and structures based on coals of different ranks and their derivatives as raw materials were summarized, and the applications of coal-based graphene and its composites in energy storage, especially in supercapacitors, lithium ion battery and sodium ion battery were introduced in detail. Finally, the main research direction of coalbased graphene and composite materials was proposed. The purpose of this review was to provide some insights and ideas for the preparation and development of coal-based new carbon materials—coal-based graphene and its composites as well as its application in the field of energy storage.
