Effect of Post- Production Thermal Treatment on Electrochemical Energy Storage Properties of Single-Walled Carbon Nanotubes.*

In this study, we will present our investigations on the effect of heat treatment on the electrical charge storage capacity of Single-Walled Carbon Nanotubes (SWCNTs) synthesized using direct decomposition of Ferrocene. Electrochemical double-layer capacitors (EDLCs) fabricated using the SWNT sheets as active electrode materials, show substantial improvements in their charge storage capacities after post-production thermal treatment. These findings will be discussed in light of the results obtained from a variety of electrochemical measurements such as cyclic voltammetry (CV), Galvanostatic Charge-Discharge (GCD) as well as Electrochemical Impedance Spectroscopy (EIS).
