摘要
We demonstrated a simple and environment-friendly method in thepreparation of N-doped carbon/PANI(NCP)composite without binder.The structureand the property of NCP have been characterized by XPS,IR,XRD,SEM,CV,GCD and EIS.The results reveal that NCP has high capacitance performance of up to 615 F·g^(-1)at 0.6A·g^(-1).Additionally,the asymmetric NCP_(300)/lcarbon supercapacitor delivers a highcapacitance(111 F·g^(-1)at 1A·g^(-1))and a capacity retention rate of 82%after 1200 cyclesat 2A·g^(-1).The ASC cell could deliver a high energy density of 39.1 W·h·kg^(-1)at a powerdensity of 792.6 W·kg^(-1).
