Abstract

Super capacitor or ultracapacitor are used for many industrial as well as commercial application like for storing electrical energy. Super capacitor is a high storage capacity capacitor with capacitance much higher than normal capacitor.In this work, we report testing and comparing supercapacitor made from copper plate and aluminum foil coated with activated carbon made of coconut husk and testing which electrolyte work best. In this experiment we tested water-based electrolytes such as KCl (Potassium chloride), Na2SO4 (Sodium sulphate), MgSO4 (Magnesium sulphate) and H2SO4 (Sulphuric acid) with different electrode and using different separator materials such as thin single layer tissue paper and thick writing paper. It was found that Cu-AC (Copper-Activated carbon electrode) with 1 molar aqueous KCl as electrolyte and Common writing paper as separator material gave the best results achieving a maximum capacitance of 3.33 farad and a maximum voltage of 1volt and theoretical energy capacity of around 1.665 joule.
