چکیده انگلیسی
Nitrogen-doped activated carbon (NAC) materials were prepared via a convenient and low-cost method from polyethylenimine (PEI) modifying commercial activated carbon (AC). After high-temperature treatment, nitrogen atoms were successfully introduced into the resulting AC matrix simultaneously the open porous structure of AC was well preserved. With the unique structure and heteroatom doping, the NAC material achieved a high capacitance value of 268â¯Fâ¯gâ1 in symmetric supercapacitor device in acidic electrolyte, as well as 226â¯Fâ¯gâ1 in organic electrolyte with 3â¯V voltage window. High energy density of 60.3â¯Wh kgâ1 obtained in NAC based supercapacitor device, suggesting the great potential for industrial application in energy storage field.
