Supercapacitors have attracted great attention from industry and academia as promising energy storage devices, due to their high power density, long life cycle and fast charge/discharge time. Carbon materials are commonly used for supercapacitor electrode materials because of their low cost, good electrical conductivity and high specific surface area. Moreover, introducing heteroatoms into carbon materials is proven to be an efficient way to improve capacitance because of faradic redox reaction and improved wettability. In this study, we have manufactured N-doped carbon nanofibers (CNFs) via electrospinning of polyazomethine (PAM) solution including poly(vinyl pyrrolidone) and following carbonization. The electrochemical performance of the PAM-derived CNFs as potential supercapacitor electrode materials was investigated by taking into accounting their microstructures. |
