| 摘 要： | 通过化学镀和电化学镀的方法制备了一种Ni(OH)2电化学活性材料修饰三聚氰胺泡沫(MF)可压缩骨架的超级电容器电极材料MF/Ni(OH)2。MF/Ni(OH)2可压缩电极材料表现出最佳的电容性能,例如循环稳定性(即使在40 mA/cm-3的电流密度下经过2000次充放电循环后,可压缩电极仍能保持90.63%的初始电容)和可压缩稳定性(即使在压缩率为50%时,仍具有97.88%的电容保持率)。层状可压缩超级电容器由MF/Ni(OH)2弹性材料作为阳极,镍/碳(Ni/C)为阴极以及实验室中常用的滤纸作隔膜材料组成。这种超级电容器装置在不同的压缩下表现出良好的电化学性能和优异的压缩稳定性。最后,使用可压缩的超级电容器来点亮LED灯,以展示其在柔性电子设备中的应用。这些优化的电化学和机械性能表明MF/Ni(OH)2可作为可压缩超级电容器的应用中的候选电极。

| Abstract: | An elastic supercapacitor electrode material with Ni(OH)2 electrochemically active material modified melamine foam(MF)compressible framework was prepared by electroless plating and electrochemical plating.The elastic electrode of MF/Ni(OH)2exhibits optimized capacitive behavior,such as cycling stability(the elastic electrode displays a capacitance retention of 90.63%even after 2000 GCD cycles at 40 mA/cm-3)and compressibility(97.88%capacitance retention at 50%compression).The layered compressible supercapacitor consists of a MF/Ni(OH)2elastic material as anode,a Ni/carbon(Ni/C)cathode,and a filter paper commonly used in laboratory acting as a diaphragm material.Such a supercapacitor device exhibits good electrochemical performance and superior compression stability under different compressions.Finally,the compressible supercapacitor was used to light a LED lamp under different compression conditions to demonstrate its application in flexible electronic device.These optimized electrochemical and mechanical properties indicate the availability of MF/Ni(OH)2as candidate electrode in application of compressible supercapacitors. |
