Abstract:
This thesis consists of three major parts based on preparation and characterization of carbon and manganese oxide nanofibers for high-performance supercapacitors. The first part is the functionalization of commercial carbon fiber paper (CFP) by a surface treatment with acids. The functionalized CFP (f-CFP) with mixed acid treatment shows higher charge storage performance than that of amine-based solvent treatment. The second part is the synthesis of carbon-based nanofiber by an electrospinning process. The effect of acetylene black (ACB) concentrations and carbon additives on the electrochemical performances of carbon-based nanofiber supercapacitors was studied. The ACB at 1 wt.% loading into as-electrospun carbon nanofiber shows the highest specific capacitance, maximum specific energy, and maximum specific power of 209 F g-1 at 2 mA, 14.2 Wh kg-1 , and 8.3 kW kg-1 in 1 M H2SO4, respectively when compared with other loading contents. The final part is the preparation of manganese oxide nanofibers by electrospinning process with following two-step heat treatment. The effect of manganese precursor contents on the electrochemical performances of manganese oxide nanofiber supercapacitors was also studied. The symmetric supercapacitor of the Mn3O4 nanofibers using 10 wt.% manganese acetate in polyacrylonitrile shows the highest specific capacitance, maximum specific energy, and maximum specific power of 289 F g-1 at 1 mA, 37.4 Wh kg-1 , and 11.1 kW kg-1 in 0.5 M Na2SO4, respectively. In addition, the average oxidation number of Mn in Mn3O4 nanofibers gets decreased after electrochemically tested and the cation adsorption/desorption on the Mn3O4 nanofibers plays a significant role in the charge storage mechanism of Mn3O4.
