Abstract

Effect of CO2 activation temperature in production of carbon electrode supercapacitor against specific capacitance has been investigated and analyzed. Carbon electrodes in this study were produced from oil palm empty fruit bunches (EFB) waste derived from people's plantations. The electrodes production were begun with cutting the cob into small flake of EFB into 5 cm length, followed by a milling process, chemical activation used a 0.3 M KOH, hydraulic pressing and followed by carbonization process at a temperature of 800 oC. The physical activation was carried out at a temperature of 800, 850, and 900 oC in CO2 gas environment. Specific capacitance was determined by cyclic voltammetry method and its found to be as high as 39.77 Fg-1, 65.84 Fg-1, 45.06 Fg-1, 41.30 Fg-1 for activation temperature of 0, 800, 850, and 900 oC, respectively . The results showed that the temperature of 800 oC was the best activation temperature in production of carbon electrodes from EFB. In addition, also calculated physical properties such as mass, thickness, and diameter were measured to determine the density of the electrode. The density of each electrode for temperature activation of 0, 800, 850, and 900 oC were 2.664 g cm-3, 1.891 g cm-3, 2.045 g cm-3, 2.131 g cm-3, respectively. As a complement, the electrode structure has also analyzed by using X-Ray Difraction method. Keywords : activated carbon , oil palm empty fruit bunches , activation of CO2 , supercapacitor.

Abstract

Supercapacitor electrodes from rubber wood sawdust based on various of chemichal activation agent of KOH, NaOH and ZnCl2 by a concentration of 0.4 M has been analyzed. The production of activated carbon electrodes was started with the process of pre-carbonization and continued with milling process. Sampel were carbonized at temperature 600 oC and followed by physical activation process in CO2 gas atmosphere at the constant temperature of 900 oC. Measurement data of mass, diameter and thickness were collected at a every step such as: (i) before carbonization, (ii) after carbonization and (iii) after physical activation processed to obtained the density values. The density of activated carbon electrodes with different of activating agent of KOH, NaOH and ZnCl2 were 0.813 g/cm3, 0.737 g/cm3 and 0.870 g/cm3, respectively. The electrochemical properties of activated carbon electrodes were analyzed by using cyclic voltammetry (CV) method for various of activating agent of KOH, NaOH and ZnCl2 were 60.650 F/g, 59.619 F/g and 103.570 F/g, respectively. As a conclution, the activated carbon with ZnCl2 activating agent has the highest of density and spesific capacitance value. As a addition the termogravimetri analysis given the information in the produce of the heating process. Keywords: Sawdust Wood Rubber, Specific Capacitance, Density, Chemical Activation.
