Porous Activated Carbon

Fibers of oil palm empty fruit bunches were carbonized at low temperature, milled and sieved to produce self-adhesive carbon grain (SACG). Grain monolith (GMs) of SACG added with 0 %, 20 % and 40 % cellulose powder were carbonized and activated to produce porous activated carbon monolith (ACMs) supercapacitor electrodes. ACMs were investigated by nitrogen adsorption–desorption isotherm and cyclic voltammetry methods to determine the effect of cellulose on the porosity and specific capacitance of the electrodes, respectively. The results showed that the addition of cellulose in GMs reduced the specific surface area of the ACMs by a factor of 94 % to 97 %, coresponding to a decrease of 31 % to 54 % in the values of specific capacitor of the ACMs supercapacitor cells.

Activated Carbon Monoliths

Binderless activated carbon monoliths (ACMs) for supercapacitor electrodes were prepared from sugarcane bagasse by two different methods of physical and combination of physical-chemical activation process. The CO2 gas was used as physical activation agent and 0.3 M KOH was chosen as chemical activation agent. The ACMs were tested as electrodes in two-electrode systems of the coin tape cell supercapacitor that consists of stainless steel as current collectors and 1 M H2SO4 as an electrolyte. The improving of resistive, capacitive and energy properties of combination of physical-chemical ACMs electrodes were shown by an impedance spectroscopy, a cyclic voltammetry and a galvanostatic charge-discharge method. The improving of resistive, capacitive and energy properties as high as 1 to 0.6 Ω, 146 to 178 F g-1, 3.83 to 4.72 W h kg-1, respectively. The X-ray diffraction analysis and field emission scanning electron microscope were performed to characterize the crystallite and morphology characteristics. The results showed that the combination of physical-chemical activation process have given a good improving in performance of the bagasse based ACMs electrodes in supercapacitor application.
