摘要

MXene材料具有组分灵活可调、电容量较高等优势在超级电容器储能领域备受关注.采用电化学法制得聚 3,4-乙烯二氧噻吩/Nb2CTx MXene(PEDOT/MXene)复合电极材料.结果表明,在扫描速率为30 mV·s-1 时,PEDOT/MXene的面积比电容可达 250.21 mF·cm-2,当电流密度从 0.1 mA·cm-2 增加到5 mA·cm-2 时,PEDOT/MXene的面积比电容保持率为 83.5%,远优于PEDOT的 64.1%,并且在 100 mV·s-1 的扫描速率下循环测试 1 000 次后初始电容保持率可达 84%,表现出良好的倍率性能和稳定性.工作为基于MXene基材料构筑高性能电化学储能界面提供了一定的借鉴.

Abstract

MXene material has the advantages of flexible composition and high capacitance,which has attracted much attention in the field of supercapacitor energy storage.In this work,the poly(3,4-ethylenedioxythio-phene)/MXene(PEDOT/MXene)composite electrode material were synthesized via electrochemical method.Experimental results indicate that the specific capacitance of PEDOT/MXene reaches 250.21 mF/cm2 at a scan rate of 30 mV/s.With the current density increasing from 0.1 mA/cm2 to 5 mA/cm2,the specific capacitance retention of PEDOT/MXene achieves 83.5%,was much better than PEDOT(64.1%).Additionally,the initial specific capacitance of PEDOT/MXene still remains 84%over 1 000 cycles at a scan rate of 100 mV/s by CV method,exhibiting good rate performance and cycle stability.This work provides a new approach to construct high-performance energy storage interface with MXene-based materials.
