초록
In this study, we manufactured the anodized alumina oxide (AAO) template and fabricated the carbon nanofibers and manganese oxide nanofibers using AAO template for application to electrochemical capacitor. Pore diameters of the AAO template were increased from 50 to 90 nm by increasing the acid treatment time after two-step anodizing process. Furthermore nanofibers, which is fabricated by AAO template, showed uniform diameter and micro structure. It is suggested that the surface area is larger than commercial electrode material and it is enhancing the energy density by increasing the specific capacitance.
