Cyclic Voltammometry of Binderless Activated Carbon Monoliths based supercapacitor from Mixtures of Pre-carbonized of Fibers of Empty Fruit Bunches and Green Petroleum Coke

Abstract

Binderless activated carbon monoliths (BACMs) prepared from mixtured of pre-carbonized of fibers of oil palm empty fruit bunches (EFB) and green petroleum coke were used for preparing the carbon based supercapacitor cells. The symmetrical supercapacitor cells were fabricated by using two BACMs electrode prepared for each selected holding time of activation and various compression pressure. The electrochemical behavior of supercapacitor cells were measured at room temperature by using cyclic voltammetry (CV) technique. The maximum specific capacitance (Csp) of the cells values were 35.9 and 82.5 F/g for holding time of activation of 1.5 and 2 h, respectively, at the compression pressure of 7.5 metric tons.
