摘　　要：超级电容器具有高比电容、长循环寿命和快速充放电的特点,其在能量的储存和转换方面展现了极高的应用价值。许多研究致力于通过改进电容器电极材料和改变电极结构来进一步提高其性能。研究发现,纳米氮化钒(VN)具有比贵金属氧化物更高的理论比电容,并且具备更优异的化学稳定性和良好的导电性。由此,VN作为超级电容器电极材料的研究受到了广泛的关注。本文首先简述了超级电容器的分类;接着,着重从合成工艺、颗粒形貌和电极性能三个方面综述了近年来超级电容器氮化钒电极材料的研究进展,最后对氮化钒电极材料的发展趋势进行了展望。Supercapacitors possess many striking characters,including high specific capacitance,long-term operation stability and rapidly charging and discharging.They also have shown excellent practical values in storage and transition of energy.Many researches were focused on improving the performance of supercapacitors by means of improving electrode materials and optimizing electrode configurations.The results indicate that nano vanadium nitride has higher potential specific capacitance than that of some noble metal oxides,and possesses excellent chemical stability and good electrical conductivity.Therefore,researches on vanadium nitrides as electrode materials of supercapacitors have attracted extensive attention.In this paper,firstly,the classification of the supercapacitors was depicted briefly.Then,the research progress of vanadium nitride electrode material for supercapacitors was reviewed from the synthesis process,the particle morphology and the performance of the electrode.Finally,the development of VN electrode material was also prospected.
