The use of matoa fruit peel waste-based activated carbon as electrode materials for supercapacitor devices is described in this paper. The chemical and CO 2 activation were used to prepared the activated carbon. In the chemical activation process, zinc chloride 0.1 M was used as a chemical reagent. Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements are used to assess the electrochemical performance of as-prepared electrode materials. After CO 2 activation process, the density of the MFP samples have been decreased. From the CV and GCD data, the MFP-0.1 sample has optimum specific capacitance are 158 F g −1 and 187 F g −1 , respectively. The electrochemical results demonstrated that the MFP sample is a potential choice for supercapacitor electrode materials.
