| Popis: | 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. |
