摘要：

Supercapacitors were fabricated using spray-deposited multiwalled carbon nanotube (CNT) films on indium tin oxide (ITO) as electrodes and solid gel as electrolytes. Specific capacitances using gel electrolyte reached up to 1.5 F/g and 9 mF/cm(2), and internal resistance was 28 Omega. Specific capacitances and internal resistance of supercapacitors with gel electrolyte were better than or comparable to those with liquid electrolytes, indicating that gel electrolytes could replace liquid counterparts in CNT-based supercapacitors. Combined with gel electrolyte, spray deposition method could provide a low cost and easily scalable process for a high performance supercapacitors using CNT films on ITO for applications in display devices.
