摘要:报道了一种新型导电聚合物聚薁胺,并制备了基于聚薁胺作为电极材料,磷酸/聚乙烯醇作为电解液的全固态超级电容器,研究了聚薁胺电容器的的基本性质。电化学测试结果表明,该器件在工作电压窗口?0.2~0.8 V下表现出优异的电容性能,可实现最大体积电容83 F/cm^(3)和最大的面积比电容0.54 mF/cm^(2),最大能量密度和最大功率密度分别为11.6 mW·h/cm^(3)和3304 W/cm^(3)。此外,该器件循环测试1000圈后仍保存初始电容的95.1%,表现出优异的循环稳定性。结果证明聚薁胺可以应用于超级电容器,为开发本征导电聚合物的探索提供了新策略。
Conductive polymers with good intrinsic conductivity and high charge density are considered as potential electrode materials for supercapacitors.However,it has been reported that the chains of polypyrrole and polyaniline could expand and contract during the charging and discharging process,leading to structural de-conformation.Poly(2-aminoazulene)is lately reported to present large area film morphology and remarkable electrical conductivity at room temperature.Nevertheless,relevant studies based on azulene as supercapacitor electrode materials have rarely been reported.Here,we report an all-solid-state supercapacitor based on a conductive polymer,poly(2-aminoazulene),as the electrode material.According to conventional electrochemical measurement,poly(2-aminoazulene)film-based device exhibits promising capacitive performance in the operating voltage window of?0.2—0.8 V:maximum volumetric capacitance of 83 F/cm^(3) and maximum areal capacitance of 0.54 mF/cm^(2),maximum energy density of 11.6 mW·h/cm^(3) and maximum power density of 3304 W/cm^(3).In addition,the supercapacitor retains 95.1%of the initial capacitance after 1000 cycles,indicating good cycling stability which enables its reliability during practical applications.These results not only prove that poly(2-aminoazulene)could be next generation candidates of all-solid-state supercapacitor electrode materials but also provide a new strategy for exploration of intrinsic conductive polymers for energy storage.
