超级电容器是近年迅速发展起来的一种新型储能元件,决定超级电容器性能的最重要因素是电极材料,开发低成本、高性能的电极材料是当前超级电容器的重要研究方向。金属有机骨架(MOFs)是一类多孔材料,由于MOFs材料的组成与结构多样、比表面积大、结构可控和可调的孔径尺寸等优势,使其在超级电容器方面的应用引起了越来越多研究人员的关注。本文综述了原始MOFs、MOFs衍生物(多孔碳、金属氧化物、多孔碳/金属氧化物)及其MOFs复合材料在超级电容器领域的应用进展,讨论了不同结构特征的MOFs及其在电化学储能领域中展现出特殊的性能,指出MOFs构筑的超级电容器在新能源储存与转换领域发挥的重要作用。最后,提出MOFs基材料应用于超级电容器领域面临的挑战和发展前景。

Supercapacitors are a new type of energy storage element that has been rapidly developed in recent years. The most important factor that determines the performance of supercapacitors is electrode materials. The development of low-cost, high-performance electrode materials is an important research direction for current supercapacitors. Metal-organic frameworks (MOFs) are a class of porous materials. The applications of MOFs in the supercapacitor have attracted more and more researchers due to their diverse composition and structure, large specific surface area, controllable structure and adjustable pore size. Recent researching application progress of pristine MOFs, MOFs-derived(porous carbon, metal oxides, porous carbon/metal oxides) and MOFs-composite materials for supercapacitors was summarized in this paper. The MOFs with different structural characteristics and their specific performance in the field of electrochemical energy storage were discussed. MOFs based supercapacitors are demonstrated to play an important role in the field of new energy storage and conversion. Finally, the current challenges, future trends and prospects of MOFs in the field of ultracapacitors were pointed out.
