【摘要】：石墨烯是一种具有大比表面积、高电导率和良好的力学性能的二维材料,在高容量和大功率储能器件方面具有广阔的应用前景。然而现有的各种石墨烯电极制造技术无论从技术层面还是在生产率、性能方面都难以满足当前工业应用的需求。石墨烯增材制造(石墨烯3D打印)在复杂三维石墨烯结构的制造方面具有突出的优势和潜力,而且还具有设备简单、成型结构可控性高等优点。关于石墨烯基电极材料的增材制造及应用在近两年内迅速发展。概述了基于增材制造制备石墨烯结构的典型技术——直写成型(DIW)的机理和优点,介绍了基于该技术制备的石墨烯基电极材料在超级电容器和锂离子电池领域的应用,最后对石墨烯基电极材料的增材制造面临的挑战和未来发展趋势进行了展望。
[Abstract]:Graphene is a two-dimensional material with large specific surface area, high conductivity and good mechanical properties. It has a wide application prospect in high capacity and high power energy storage devices. However, the existing graphene electrode manufacturing technology is difficult to meet the needs of current industrial applications in terms of technology and productivity. Graphene fabrication (graphene 3D printing) has outstanding advantages and potential in the manufacture of complex three-dimensional graphene structure, and also has the advantages of simple equipment and high controllability of forming structure. The fabrication and application of graphene-based electrode materials have developed rapidly in the last two years. In this paper, the mechanism and advantages of direct writing molding (DIW), a typical technology for fabricating graphene structure based on material augmentation, are summarized. The applications of graphene based electrode materials based on this technology in the field of supercapacitors and lithium ion batteries are introduced. Finally, the challenges and future development of graphene-based electrode materials are prospected.
