摘要

本文制备了二氧化锰和聚苯胺碳的复合电级材料(MnO2-PAnC),测试结果表明MnO2-PAnC材料为松散结构组成的纳米颗粒. MnO2-PAnC 材料的比电容最大可达459 F•g-1,MnO2-PAnC电极在较高的扫速下循环伏安曲线变形较小,表现出良好的可逆性. 交流阻抗测试结果表明,MnO2-PAnC 电极电荷传递电阻小,表面离子扩散速度快. 充放电500个循环后,MnO2-PAnC 电容的保持率仍高于60%. 以上实验结果表明,MnO2-PAnC 是很好的超级电容器的电极材料.

Abstract

The polyaniline-carbon (PAnC) electrode was prepared by the polymerization of aniline monomer and activated carbon in ice water bath, and followed by chemical deposition of manganese dioxide MnO2-PAnC composite material. The specific capacitance of MnO2-PAnC reached 459 F•g-1. The cyclic voltammetric results showed a small deformation in the voltammogram curve obtained with the MnO2-PAnC electrode at high scan rate, indicating good reversibility and capacitive properties. The AC impedance results revealed that the MnO2-PAnC electrode displayed the smallest charge transfer resistance and the fastest diffusion
rate of surface ions than other two materials of MnO2 and MnO2-C. After 500 cycles of charging and discharging processes, the capacitance retention rate of MnO2-PAnC was still higher than 60%. The MnO2-PAnC is promising as a good electrode material for supercapacitors.
