Supercapacitors are promising power source for automotive applications, have many advantages such as high power density, high rate capability, long durability. Electrochemical supercapacitors can be fallen into two categories. First, electrochemical double-layer capacitors, which are due to charge-discharge separation, second pseudo capacitors, which are derived from redox reactions. Polyaniline (PANI) nanotubes have great potential electrical application in supercapacitor electrode material. For the preparation of PANI-included nanofibers with high electrical conductivity, in situ polymerization of aniline was utilized using the electrospun nylon 6,6 fiber as a template. The morphology of the modified nanotubes has been carefully analyzed by field emission scanning electron microscopy, The electrochemical performances of which were examined using cyclic voltammetry (CV) and galvanostatic charge/discharge test, and electrochemical impedance spectroscopy (EIS) analysis. |
