Abstract

 

Electrode materials play an important role in the performance of the supercapacitor. The combination of nanosized carbon materials and TiO2 is one of the advanced solutions to improve the electrochemical properties of the electrode. In this study, we synthesized TiO2@CNTs nanocomposite materials using the sol-gel method and studied the electrochemical properties of the synthesized materials. The composite TiO2@CNTs materials have anatase-like structures and grain sizes in the range of 300-700 nm. Adding CNTs to the product increases thermal stability and the specific surface area of the material. Electrochemical results show that TiO2@1%CNTs composite electrode stores energy by pseudocapacitor mechanism, the highest specific capacitance in 1M Na2SO4 solution is 218.6 F.g-1. Moreover, the TiO2@CNTs electrodes operate stably for over
1200 cycles.
