Abstract:
Amongst the current trend in the study of carbon composite electrodes is the addition of
carbon nano particles, without binding materials, into conventional carbon to produce
electrode in order to benefit from both the unique property of the nano particles and the
absent of the binder which can improve the specific capacitance of the electrodes. In our
study, we produce the binderless carbon/carbon nanotubes composite electrodes for
supercapacitor application from the green pellets consist of self-adhesive carbon grain
from fibers of oil palm empty fruit bunch and 0, 6 and 8% carbon nanotubes (CNTs),
respectively. This paper reports the electrodes properties, i.e., microstructure, electrical
conductivity, porosity and electrochemical, based on the characterization using Field
Emission Scanning Electron Microscope, four-point-probe, nitrogen adsorptiondesorption
isotherm, electrochemical impedance spectroscopy and cyclic voltammetry
techniques. The results show that supercapacitor cell using the electrodes with 6%
CNTs has a better supercapacitive behavior.
