摘　　要：锌离子混合电容器具有高能量密度、高功率密度、长寿命、高安全性、环保以及低成本等优点,得到了极大的关注。设计合成高性能的正极材料用于匹配具有高理论容量的锌负极是目前研究热点。本文首先以金属有机框架ZIF-67为模板衍生制备出碳纳米管(CNT),然后将聚苯胺(PANI)沉积在CNT上制备PANI@CNT复合正极材料。实验结果表明,在电流密度为1 A/g时,PANI@CNT//Zn器件比容量高达150.11 mAh/g,在经过3000次循环充放电后,容量没有衰减,这些性能均优于单独的PANI材料。本文为开发新型的高性能锌离子混合电容器正极材料提供了参考。Zinc ion hybrid capacitor has the advantages of high energy density,high power density,long lifespan,high safety,environmental friendliness,and low cost,which has received great attention.Designing and synthesizing high-performance cathode materials to match high-theoretical-capacity zinc anodes is currently a hot research topic.Herein,the metal-organic framework of ZIF-67 is firstly used as a template to prepare carbon nanotubes(CNTs),then deposits polyaniline(PANI)on CNTs to fabricate PANI@CNT composite cathode materials.The results show that the PANI@CNT//Zn device has a high specific capacity of 150.11 mAh/g at the current density of 1 A/g,and the capacity does not decay after 3000 cycles.These performances are superior to those of the individual PANI material.This work provides a new way for the development of high-performance zinc-ion hybrid capacitor cathode materials.
