摘要：采用KOH活化法制得高比表面积的活化多孔碳(aHPC),借助原位化学氧化法制得疏松多孔的活化多孔碳负载聚苯胺纳米复合材料(aHPC@PANI),并分别以aHPC及aHPC@PANI为负极与正极,以四乙基氟硼酸-乙腈为电解液,构建有机非对称超级电容器。电化学测试结果显示:在1A/g电流密度下,aHPC@PANI正极与aHPC负极分别呈现256.7F/g(-0.6~0.8V)及152.4F/g(-2^-0.6 V)的比容量;所组装的有机非对称电容器呈现宽电位窗口(2.8V),高的能量密度(在0.75kW/kg功率密度下为56.2 W·h/kg)及优异的循环稳定性(循环5000次后其比电容保持率高达92.4%)。
Activated porous carbon(aHPC)with large surface area is fabricated by the KOH activation method,and the porous aHPC supported polyaniline nanocomposite(aHPC@PANI)is fabricated by the in-situ chemical oxidation method.The organic asymmetric supercapacitor is further designed using aHPC as negative electrode and aHPC@PANI as positive electrode in the Et4NBF4-AN electrolyte.The electrochemical tests show that aHPC@PANI and aHPC deliver the specific capacitance of 256.7 F/g(-0.6-0.8 V)and 152.4 F/g(-2--0.6 V)at the current density of 1 A/g,respectively.The as-synthesized organic asymmetric supercapacitor achieves wide potential window(2.8 V),high energy density(56.2 W·h/kg at the power density of 0.75 kW/kg),and excellent cycling stability(the specific capacitance retention is 92.4%after 5000 cycles).
