Abstract
The invention relates to the technical field of electrode material preparation and particularly discloses a nitrogen element self-doped tobacco stem-based activated carbon electrode material and a preparation method and application thereof. The preparation method of the nitrogen element self-doped tobacco stem-based activated carbon electrode material comprises the following steps of (1) plantingflue-cured tobacco; (2) taking tobacco straw, crushing the tobacco straw to obtain tobacco straw powder, and then drying the tobacco straw powder; (3) carrying out pyrolysis treatment on the dried tobacco stem powder in a nitrogen atmosphere to obtain a tobacco stem carbon powder precursor; (4) mixing the tobacco stem carbon powder precursor with KOH, adding water for further grinding and kneading, and drying to obtain a tobacco stem carbon powder/KOH mixture; and (5) carrying out pyrolysis treatment on the tobacco stem carbon powder/KOH mixture to obtain the tobacco stem-based activated carbon electrode material self-doped with the nitrogen element. When the cigarette-stem-based activated carbon electrode material is used for preparing a supercapacitor, the specific capacitance of the supercapacitor can be improved, and the energy density can be increased.
