Nowadays, new technologies try to generate more energy to satisfy the demand of electricity. Therefore, storage of generated energy is becoming a highly important task. It is well known that the supercapacitors and batteries play a major role in the field of energy storage. When considering those options for storage electricity, supercapacitors were able to replace most of the capabilities encompassed in batteries and conventional capacitors with high energy density and the power density. In this research article, fabricating a novel supercapacitor using local coconut shell charcoal was discussed. It was focused on improving its performances without using a binder compound while keeping the fabrication process simple and inexpensive. Activated carbon powder used to fabricate the supercapacitor in this research was made from local coconut shell charcoal which was activated using steam activation method. The electrodes were fabricated as an electrode slurry made of activated carbon powder mixed with potassium hydroxide (KOH). It is found that the highest specific capacitance could obtain from the supercapacitor was 137 F/g. Charge-discharge curve indicated a power density of 42.6 Wkg-1 and energy density of 14.58 Whkg-1 which was a remarkable improvement for a supercapacitor fabricated without a binder compound.Keywords

We developed activated carbon from the Aegle marmelos fruit shell also known as Beli. Firstly, its carbonaceous process is done by a typical process. H3PO4 treatment was used to activate the carbonaceous material. Activated material is characterized by using Scanning Electron Microscope and Brunauer-Emmett-Teller (BET) specific surface areas. Calculated BET surface area of the fabricated supercapacitor is 517 m2/g. Electrochemical characterization was carried out through cyclic voltammetry, charge/discharge and electrochemical impedance spectro-scopy. Highest specific capacitance of 59 F/g and energy density of 8.19 kW/h for highest specific capacitance was obtained from the charge discharge curve. Obtained equivalent serial resistance is 0.414 Ω from equivalent circuit.Keywords
