摘      要：Carbon nanofibers(CNFs)with excellent electric conductivity and high surface area have attracted immense research interests in ***,the macroscopic production of CNFs still remains a great ***,ultrafine N–doped CNFs(N–CNFs)with a diameter of$20 nm are synthesized through a simple and scalable sol-gel method based on the self-assembly of phenolic resin and cetyltrimethylammonium *** employed in aqueous supercapacitors,the obtained activated N–CNFs manifest a high gravimetric/areal capacitance(380 Fg-1/1.7 Fcm-2)as well as outstanding rate capability and cycling ***,the activated N–CNFs also demonstrate excellent capacitive performance(330 Fg-1)in flexible quasi-solid-state *** remarkable electrochemical performance as well as the easy and scalable synthesis makes the N–CNFs a highly promising electrode material for supercapacitors.
