: Analisis Kinerja Superkapasitor Pada 3 (Tiga) Jenis Kombinasi Zat Additive P-Phenylenediamine Dan Hydroquinone Pada Elektrolit Berbasis Kalium Hidroksida (KOH)

Abstract

Supercapacitors have a fairly low capacitance value when compared to batteries. In terms of improving its performance, supercapacitor electrolytes can be developed by adding additives. P- Phenylnediamine and Hydroquinone are additives that can improve the performance of supercapacitors. The purpose of this study was to determine the effect of p-Phenylnediamine and hydroquinone additives when added to potassium hydroxide electrolyte and determine the optimal amount of p-Phenylnediamine and hydroquinone levels. The research method will be carried out using the AutoLab potentiostat. The tests carried out are CV and EIS tests, based on these tests, the electrochemical values can be calculated. Based on the results. Based on this research, adding p- Phynelenediamine and hydroquinone additives has been shown to improve the performance of the supercapacitor.
