PEMBUATAN ELEKTRODA KARBON DARI BIOMASSA CANGKANG BIJI MANGGA UNTUK APLIKASI SEL SUPERKAPASITOR

Abstract

Supercapacitors are renewable energy storage devices that have good cycle performance consisting of components, namely electrodes, electrolytes, current collectors, and separators. Electrodes are one of the most important components in supercapacitors because they can improve the performance of supercapacitor cells. The process of making carbon electrodes carried out is the pre-carbonization process, chemical activation with 0.5 M KOH activator, the carbonization process using N2 gas at a temperature of 600 C and physical activation using CO2 gas at a temperature of 800 C. The carbon electrodes were given the sample code CBM-05. The results of the characterization of the physical properties of the carbon electrode obtained a density with a mass loss percentage value of 31.52%. Characterization of electrochemical properties of CBM-05 supercapacitor cells obtained a specific capacitance value of 158 F/g. The results of the characterization of physical properties and electrochemical properties showed that carbon electrodes could be made from mango seed shell biomass which can improve the performance of supercapacitor cells..
