摘要
在当今纳米尺度下,能源存储问题正成为世界上大多数国家科学家关注的焦点。具有高功率密度的超级电容器已成为推动储能技术重大发展的最有潜力的器件。石墨烯由于具有许多优异的性能,如比表面积高达2600m^(2)/g、电荷迁移率高达230000cm^(2)/(V·s),导热系数为3000W/(m·K),最高强度为130GPa,被广泛应用于超级电容器电极材料。介绍了石墨烯的制备方法、石墨烯的性能及零维、一维、二维和三维石墨烯基复合材料电极的制备方法。最后指出了石墨烯基电极材料面临的主要挑战和未来的展望。
In today's nanoscale regime,energy storage is becoming a hot topic in the world.Supercapacitor with high power density has emerged out as the most promising component to facilitate the development of energy storage technology.Graphene material has been widely used for electrode material of supercapacitor due to its exceptional intrinsic properties such as highest theoretical specific surface area(2600m^(2)/g),high electrical charges mobility[230000cm^(2)/(V·s)],thermal conductivity[3000W/(m·K)],and highest strength(130GPa).In this paper,the preparation method and the properties of graphene,as well as the preparation method of zero-dimensional,one-dimensional,two-dimensional and three-dimensional graphene-based composite electrodes were introduced.Finally,the main challenges and prospects were discussed.
