摘要:
采用恒电流法在高导电性石墨烯膜的表面均匀沉积氢氧化镍，制得电化学性能优异的柔性氢氧化镍/石墨烯膜。运用场发射扫描电镜(FESEM)和X射线衍射(XRD)对实验制备的氢氧化镍/石墨烯膜进行了形貌和结构分析，通过循环伏安法(CV)和恒电流充放电测试在6〖KG3x〗mol ·L-1的KOH 溶液中研究了氢氧化镍/石墨烯膜电极的电化学性能。研究结果显示，花状α型氢氧化镍能够均匀分散在柔性石墨烯膜表面。沉积50 s时制备的氢氧化镍/石墨烯膜的电化学性能最佳，在电流密度1、2、3〖KG3x〗A·g-1下的比电容依次为1 897、1 736、1 699〖KG3x〗F·g-1。更为重要的是，组装的非对称电化学电容器氢氧化镍/石墨烯膜—石墨烯膜在电流密度1〖KG3x〗A·g-1条件下循环1 000圈之后的电化学比容量还能保留原来的97.8%。氢氧化镍/石墨烯膜电极具有电化学容量高、循环寿命长和制备过程简单等优点，是一种很有前景的超级电容器电极材料。
Abstract:
Flexible nickel hydroxide/graphene film was synthesized by evenly electrodepositing nickel hydroxide on highly conductive graphene film using constant current method. The synthesized nickel hydroxide/graphene film was characterized by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analysis. The electrochemical capacitance behavior of the nickel hydroxide/graphene film electrode was investigated by cyclic voltammetry(CV) and galvanostatic charge-discharge studies in 6〖KG3x〗mol·L-1的KOH solution. The experimental results showed that flower-like α-Ni(OH)2 could be uniformly dispersed on foldable graphene film and the sample that was electrochemically deposited for 50 s exhibited optimum electrochemical performances. The specific capacitance can reach 1 897，1 736 and 1 699〖KG3x〗F·g-1 at 1，2〖KG3x〗A·g-1 and 3〖KG3x〗A·g-1, respectively. More importantly, the specific capacitance retention ratio of the assembled Ni(OH)2/graphene film-graphene film asymmetric supercapacitor still can maintain 97.8% after 1 000 galvanostatic charge-discharge cycles at 1〖KG3x〗A·g-1. The synthesized nickel hydroxide/graphene film showed high specific capacitance, long cycle life and simple synthesis process and was considered as one promising electrode material.
