摘要:
通过研究聚3,4-乙烯二氧噻吩/泡沫镍（PEDOT/NF）复合电极材料中活性物质PEDOT沉积量对超级电容器性能的影响，获得了PEDOT/NF复合电极最佳的电化学性能。采用电化学工作站循环伏安法，在电压窗口为0～1 V、扫描速率为100 mV/s的条件下，通过一步法将单体3,4-乙烯二氧噻吩（EDOT）电镀到具有较大比表面积以及高电导率的NF上制备PEDOT/NF复合电极，通过扫描电子显微镜（SEM）和X射线能谱仪（EDS）对PEDOT/NF复合电极的形貌和元素组成进行分析，通过循环伏安法以及恒电流充放电对PEDOT/NF复合电极的电化学性能进行系统研究。SEM和EDS检测结果表明，PEDOT均匀、一致地聚合到了NF的骨架上且与NF紧密结合。经测试计算，PEDOT/NF复合电极材料在扫描速率为10 mV/s时质量比电容可以达到30868 F/g，在恒电流充放电中最小电阻为11.26 Ω，功率密度为1444 W/kg时能量密度为16.03 Wh/kg，经过3000圈伏安循环后电容仍可以保持在其最大电容的79.2%。采用PEDOT/NF复合电极材料制作的超级电容器具有高的质量比电容、大的能量密度和功率密度、较小的电阻以及优良的循环稳定性，展现出卓越的性能。
Abstract:
The optimum electrochemical performance of the poly(3,4-ethylenedioxythiophene)/nickel foam (PEDOT/NF) composite electrode was obtained by studying the effect of PEDOT amount on the performance of the supercapacitor. Monomer 3,4-ethylenedioxythiophene (EDOT) was electroplated on NF with a larger specific area and high conductivity by one-step method, which adopted the cyclic voltammetry of electrochemical workstation with a voltage window from 0 to 1 V and scan rate of 100 mV/s. The morphology and element composition of the PEDOT/NF composite electrode were analyzed by scanning electron microscopy (SEM) and X-ray energy spectroscopy (EDS). The electrochemical performance of the PEDOT/NF composite electrode was systematically studied by electrochemical cyclic voltammetry and constant current charge and discharge. The results of SEM and EDS indicate that PEDOT is uniformly polymerized onto the backbone of NF and tightly combined with NF. The PEDOT/NF composite electrode material has a mass specific capacitance of 308.68 F/g at a sacn rate of 10 mV/s, a minimum resistance of 11-26 Ω at a constant current charge-discharge, energy density of 16.03 Wh/kg at the power density of 1444 W/kg, and 79.2% of the maximum capacitance after 3000 cycles in cyclic voltammetry. Supercapacitors using PEDOT/NF as electrode materials exhibits high mass specific capacitance, large energy density and power density, low resistance, excellent cycle stability, which shows excellent capacitor performance.
