“…Both of synthesized activated carbon and commercial activated carbon supercapacitor have a big ohmic resistance number and commercial activated carbon supercapacitor has greater interphase resistance (Rp) than the synthesized activated carbon supercapacitor. Moreover the ohmic and interphase resitance in this research was higher compared to the study conducted by Pramujo et al [17] which ohmic and interphase resistance generated from their supercapacitor cell were 4.9 ohm and 5.4 ohm. This phenomenon might be happen due to the electrolyte dried rapidly because the sealing system was non-optimal.…”

“…This phenomenon might be happen due to the electrolyte dried rapidly because the sealing system was non-optimal. In addition the difficultness of electrolyte diffusion within the entire electrode surface made the both supercapacitor cell from present research have higher ohmic and interphase resistance [17]. Based on the EIS analysis, the interphase resistance of commercial activated carbon supercapacitor causes the capacitance of supercapacitor cell becomes smaller which is suitable with the results from calculations performed by cyclic voltammetry (CV) analysis.…”

“…The capacitance is not affected by the surface area of materials. The lower specific capacitance of commercial activated electrode could be caused due to imperfect interphase connection [17]. This imperfect cell sealing system could cause the presence of reactive and unstable oxygen functional groups which can interfere the ion transfer process [18].…”

Palm oil waste as biomass resources in Indonesia were not fully utilized. One of the product that can be made from oil palm biomass is activated carbon. Activated carbon characteristic with high porosity and good conductivity, made activated carbon suitable as supercapacitor electrode material. Activated carbon preparation consists of two main steps that are carbonization and activation. In this research carbonization carried out by hydrothermal process while activation conducted by physcal activation. This research focused on manufacturing activated carbon from palm oil waste by hydrothermal carbonization for supercapacitor application. Activated carbon produced from empty fruit bunch have a surface area of 330 – 1181 m2/gr, pore volume of 0.19 – 0.69 cm3/gr, and pore size of 2.1 – 2.3 nm. While activated carbon produced from oil palm shell have surface area of 8 – 451 m2/gr, pore volume 0.05 – 1.064 cm3/gr, and pore size 2.9 – 20.7 nm. The crystallinity of the activated carbon obtained ranged from 46.5 to 51.9%. In this study, the activated carbon is used as a working electrode on an asymmetric hybrid supercapacitor with nickel oxide being used as second electrode. This palm oil-based supercapacitor cell has a capacitance of 1.7554 F/g.

Nanostructured materials have greatly improved the performance of electrochemical energy storage devices because of the increased activity and surface area. However, nanomaterials (e.g. nanocarbons) normally possess low packing density, thus occupy more space which restricts their suitability for making electrochemical devices as compact as possible. This has resulted in their low volumetric performance (capacitance, energy density, and power density), which is a practical obstacle for the application of nanomaterials in mobile and on-board energy storage devices. While rating electrode materials for supercapacitors, their volumetric performance is equally important as the gravimetric metrics and more reliable in particular for systems with limited space. However, the adopted criteria for measuring the volumetric performance of supercapacitors vary in the literature.Identifying the appropriate performance criteria for the volumetric values will set a universal ground for valid comparison. Here, the authors discuss the rationale for quantifying the volumetric performance metrics of supercapacitors from the three progressive levels of materials, electrodes and devices. It is hoped that these thoughts will be of value for the general community in energy storage research.

This work focuses on the development of a novel type of chemically activated carbon networks composited with the graphene oxide. Here, the carbon networks were derived from green biomass wastes such as orange peels, banana peels and potato starch. All the obtained carbon materials were being activated using different activating agents based on the higher specific capacitance such as phosphoric acid activated orange peel derived carbon, sulphuric acid activated banana peel derived carbon and hydrochloric acid activated potato starch. Further they were individually composited with graphene oxide for enhanced performance. Different chemical activation is employed for the sake of obtaining higher specific capacitance, energy and power density. Phosphoric acid activation on orange peel derived carbon network was selected due to the improvement in the micropores and further increased the surface area with the controlling capability of structures of activated carbon. To improve the conductivity of the samples, graphene oxide was added. The electrochemical performance of orange peel, banana peel and potato starch derived nano porous activated carbon materials composited with graphene oxide for supercapacitor applications is evaluated using aqueous H2SO4 electrolytes at a scan rate of 10 mV s-1. The samples that are prepared are structurally characterized using fourier transform infrared spectroscopy, x-ray diffraction and electrochemically characterized using cyclic voltammetry, galvanostatic charge and discharge measurements, and electrochemical impedance spectroscopy. From the electrochemical measurements, suitability of material as electrode for supercapacitors can be understood. The superior electrochemical performance is attributed in orange peel derived nano porous carbon/ graphene oxide due to porous structure.
