Energy storage technologies are gaining more and more importance due to the increasing energy

demand in recent years. The energy crisis and the harmful effects of fossil fuels on the environment

have led to the development of new technologies for highly efficient, easily manufactured, and lowcost

energy storage devices. Supercapacitors are ideal energy storage devices because of their highpower

density, high charge/discharge rates, long cycle life, and excellent cycle stability. The

supercapacitor electrode active material can consist of various conductive polymers, carbon materials,

and metal oxides [1]. Conducting polymers are used as electrodes in supercapacitors due to their high

capacitance, good electrical conductivity, stability under environmental conditions, low cost, and easy

production [2]. Carbon materials are used in supercapacitors because of their high conductivity and

electroactive areas [3]. Metal oxides are also used to provide strong faradaic reactions by exhibiting

low internal resistance [4]. This study chemically synthesized supercapacitor active material using

polyaniline, graphene, and metal oxide. The modified active material was characterized using FTIR and

SEM techniques. Graphene/conducting polymer/metal dioxide supercapacitor device performance was

evaluated by cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance

spectroscopy techniques.
