MANUFACTURING METHOD OF NITROGEN/FLUORINE CO-DOPED HOLLOW CARBON SPHERE AND ITS APPLICATION TO SUPERCAPACITOR

摘要

The present invention relates to a method for synthesizing supercapacitor electrode materials and the control of electrode material properties. The present invention proposes a method for synthesizing supercapacitor electrode materials having a large surface area and high activity by removing silica using a hydrofluoric acid solution after heat treatment and forming an aniline film co-doped with nitrogen and fluorine on silica. The present invention shows a characteristic in which a fluorine content is controlled according to a ratio of an aniline monomer to a fluorine aniline monomer; the fluorine content according to the presence or absence of iron and cobalt, and the difference in performance thereby; and the application thereof to a supercapacitor, thereby suggesting improved performance and stability.
