The study demonstrated a simple and environmentally friendly method for preparing N-doped carbon/PANI composite without binder, showing high capacitance performance and cycling stability for potential use in high energy density supercapacitors.
We demonstrated a simple and environment-friendly method in the preparation of N-doped carbon/PANI (NCP) composite without binder. The structure and 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 center dot g(-1) at 0.6 A center dot g(-1). Additionally, the asymmetric NCP300//carbon supercapacitor delivers a high capacitance (111 F center dot g(-1) at 1 A center dot g(-1)) and a capacity retention rate of 82% after 1200 cycles at 2 A center dot g(-1). The ASC cell could deliver a high energy density of 39.1 W center dot h center dot kg(-1) at a power density of 792.6 W center dot kg(-1).
