The application of carbon nanotubes has been considered to be an effective approach for the improving capacitance of the eletric double-layer capacitors(EDLC). For multi-walled carbon nanotube(MWNT) supported TiO2 composite material were prepared by sol-gel methods. The electrochemical capacitance and resistance of TiO2/MWNT composite electrode were characterized by cyclic voltammetry, charge-discharge test and electrochemical impedance spectroscopy. We discussed that content of TiO2 nano particles has influence on the total capacitance at TiO2/MWNT composite electrode at EDLC system. |
