In the rapid development of modern society , especially in the oil , coal , natural gas and other traditional energy sources are depleted the context of the times , the development of new sources of energy , and the device is imminent. Super capacitor is a new type of energy storage device between the conventional capacitor and between the battery cells , with a much higher energy density than conventional capacitors , a much higher power density than batteries , superior cycle efficiency and a long cycle life ( more than 100,000 ) . Supercapacitor research , development higher than the capacity of the electrode material has an important application value and theoretical significance . In this paper, by using a simple method of preparation of a regular morphology , and electrochemical properties of the electrode material - polyaniline -based carbon nanotube . In the experiment, directly by rapid mixing polymerization nanotube structure of polyaniline was prepared , and on this basis , after the high temperature treatment , the nanotube polyaniline is converted into a nitrogen-containing carbon nanotubes , carbonization temperature of polyaniline carbon tubes morphological and electrochemical properties . The results show that : the polyaniline-based carbon nanotube diameter is about 100 nm, a length of a few microns , the pipe cross each communicating pipe open at both ends , having a very low ratio of surface area . Polyaniline-based nanotubes as the capacitor electrode material exhibited a high specific capacity and good cycle performance , in particular, is 700 degrees of the carbonized product , under a current density of 0.1A · g-1 , 163 F · g- 1 than capacity . Tested by XPS analysis research polyaniline-based carbon nanotube has good electrochemical performance reasons , the results show that the nitrogen element in the substance bound on the electrical properties of the electrode material plays an important role . 400.5 eV at the pyrrole nitrogen or hydroxy pyridine nitrogen ( N - 5 ) ; , and located within the graphite layer of four yuan nitrogen (401 eV: NQ), the presence of a combination of both nitrogen atoms improve the electron donating ability of the electrode material and the wettability of the electrolyte on the electrode material , thereby improving the electrical properties of the electrode material .
