摘　　要：超级电容器是一种介于电介质电容器和电池之间的储能装置,它拥有强大的输出功率、长效的使用寿命以及快速充放电能力,长期以来备受关注。作为一种新型超级电容器电极材料,三维石墨烯(3DGN)能够缩短电解质离子的扩散距离,提供快速电子输运通道,并能充当骨架与过渡金属氧化物进行复合,实现两者的协同作用。本文介绍了三维石墨烯的不同制备工艺,在此基础上,对三维石墨烯与过渡金属氧化物的复合工艺进行了进一步的总结。最后对三维石墨烯/过渡金属氧化物在超级电容器应用中的优势及目前存在的问题进行了概括分析。As an intermediate energy storage devices between dielectric capacitors and batteries,supercapacitors have attracted intense attention mainly due to their unique properties such as high output power,long cycling stability,and fast charge/discharge capability.Three dimensional graphene(3DGN)is currently pursued as supercapacitor electrode because it can provide short diffusion pathways for electrolyte ions and fast transport channels for electrons,and act as an ideal scaffold for forming transition metal oxide to obtain a synergistic effect.This review aims to describe the different synthetic processes with respect to 3DGN.In particular,various compound processes of 3DGN and transition metal oxide are summarized.Finally,the superiorities and the challenges of the application of three dimensional grapheme/transition metal oxide in supercapacitors are presented in the end of the review.
