Description
技术领域
本发明涉及一种用电化学沉积制备聚吡咯/氢氧化镍超级电容器复合电极材料的办法,具体的来说,涉及一种聚吡咯/氢氧化镍超级电容器复合电极材料的制备方法。
背景技术
聚吡咯作为一种常见的导电聚合物,由于其制备简单,成本低廉,以及具有良好的环境稳定性和独特的物理和化学性质,常常被用于超级电容器、电池、传感器以及防腐领域,得到了世界各国科研工作者的大力关注。特别是具有纳米结构的导电聚吡咯,由于其粒径极小、比表面积大、极快的电子转移速率等性质,赋予了纳米导电聚吡咯材料具有传统块体所不具备的许多独特性能。
氢氧化镍作为一种超级电容器的电极材料,因为能够提供赝电容,在碱性电解质中特定容量高、稳定性好等特点,成为碱性超级电容器电极材料的研究热点。层状的双氢氧化物(Layered Double Hydroxide,简称 LDHs),有着独特的层状结构,在化学传感器、电催化、超级电容器中,都有广泛的应用研究。((a) Chen, J.; Xu, J.; Zhou, S.; Zhao, N.;Wong, C. P., Amorphous nanostructured FeOOH and Co–Ni double hydroxides forhigh-performance aqueous asymmetric supercapacitors. Nano Energy 2016, 21,145-153; (b) Wang, L.; Feng, X.; Ren, L.; Piao, Q.; Zhong, J.; Wang, Y.; Li,H.; Chen, Y.; Wang, B., Flexible Solid-State Supercapacitor Based on a Metal-Organic Framework Interwoven by Electrochemically-Deposited PANI. Journal ofthe American Chemical Society 2015, 137 (15).)
虽然氢氧化镍作为超级电容器电极在容量上虽然比较有优势,但是一般电化学窗口比较窄和导电性较差。聚吡咯在复合电极之中可以起到拓宽电化学窗口和增强导电性的作用。本发明以吡咯单体和镍盐水溶液为电解液,通过循环伏安的办法在同一电极上同时进行阳极沉积聚吡咯和阴极沉积氢氧化镍,是一种简单且环保的制备方法,所得复合材料结构规整且具有良好的电化学性能,是一种理想的超级电容器电极材料,尤其是适合工业化生产。
发明内容
本发明的目的在于提供一种聚吡咯/氢氧化镍超级电容器复合电极材料的制备方法。
具体步骤为:
(1)将吡咯单体加入到镍离子浓度为0.1~2M的水溶液中,室温搅拌2h直至吡咯单体完全溶解,制得电解液。
(2)取50mL步骤(1)制得的电解液置入电解槽,以压实碳纸或者石墨烯纸为工作电极和对电极,饱和甘汞电极为参比电极,配置三电极体系,以5~2000mV/s的扫描速率在-1V~1V之间对体系进行循环伏安扫描100~10000圈。
(3)反应结束后,取下步骤(2)的工作电极和对电极,用去离子水浸泡过夜以去除杂质离子,在60℃下烘干24h,即制得聚吡咯/氢氧化镍超级电容器复合电极材料。
所述吡咯单体和镍离子的物质的量之比为0.1~5:1。
本发明方法制备过程简单、环保、可靠,原料来源广泛、成本低廉,适合工业化生产,所制得的聚吡咯/氢氧化镍超级电容器复合电极材料兼具高电导率和高的电容量,有着更大的电化学窗口、更高的比电容,是一种理想的超级电容器电极材料。
