Electrode materials nitrogen doped MWCNTs:

1. Heterogeneity elemental nitrogen-doped carbon nanotubes can be effective in controlling the crystal structure and the electronic structure of carbon nanotubes to produce superior physical and chemical properties of pure carbon nanotubes.

2. Nitrogen atoms doped carbon nanotubes can cause distortion of the hexagonal topology, so as to increase the concentration of nitrogen-doped carbon nanotubes become bent by the relatively flat, while the increase is better than the defective wall roughened. Doping nitrogen atom reduces the thermal stability of the obtained product.

3. Carbon nanotubes electrode stability, high efficiency, with better response rates at high current, is a more superior supercapacitor electrode material. Nitrogen doping reduces the contact resistance and equivalent series resistance of carbon nanotubes electrodes, increase the frequency response.

4 nitrogen atoms doped carbon nanotubes changes polarity, making it easier to infiltrate the electrolyte in the carbon nanotube networks, improved electrochemical properties that have a good effect.
