摘要/Abstract

摘要： 用液相沉淀法制备了二氧化锰/酸化多壁碳纳米管(MnO₂/SMWCNT)和二氧化锰/酸化多壁碳纳米管/聚苯胺(MnO₂/SMWCNT/PANI)电极材料。通过循环伏安、恒电流充放电等方法测试了样品的电化学性能。结果表明, 当MnO₂:SMWCNT:PANI的质量比为1:1:0.4时,它的电化学性能最好, 在0.1 A/g电流密度下的比电容为318.6 F/g, 氧化电流为6.02 A/g, 循环100次后电流保持率保持在92.7%。

Abstract: Binary MnO₂/acidified multi-walled carbon nanotube (SMWCNT) and ternary MnO₂/SMWCNT/ polyaniline (PANI) composites were prepared by liquid-phase precipitation method. SEM images show that the morphology of the materials presents a typical porous structure. The electrochemical capacitive performance of the prepared samples in 0.1 mol/L K₂SO4 solution was investigated by cyclic voltammetry and galvanostatic charge/discharge tests. The binary MnO₂/SMWCNT composites exhibits improved capacitance compared with the SMWCNT. Further, the ternary MnO₂/SMWCNT/PANI composites display quasi-rectangular voltammogram shapes and high capacitor properties. The sample with the mass ratio of MnO₂:SMWCNT:PANI=1:1:0.4 displays the best performance in all electrode materials. The specific capacitance of the sample reaches 318.6 F/g at the current density of 0.1 A/g, and its oxidation current density reaches 6.02 A/g. 92.7% current value is maintained after 100 cycles. The high electrochemical capacitors of the ternary MnO₂/SMWCNT/PANI composites may be ascribed to their porous morphological structure and well-dispersed MnO₂ particles on SMWCNT and PANI.

Key words: MnO₂, polyaniline, multi-walled carbon nanotube, electrochemical capacitor
