Abstract

Energy is the basic need required for the human survival and the survival of other countless species on this mother planet. Early human beings used wood as stored energy resource in order to get heat and light. Later as the civilization progresses the human quest of finding more and more energy source dramatically increased in order to fulfill their desire. Over the thousands of years human civilization used the stored energy what is now referred to as fossil fuels. This chemical energy stored within the earth’s crust from organic materials which have decayed over many millennia. This chemical energy is able to be converted to other forms of usable energy, including that of electrical energy. But today this primary energy source is under serious extinction. Global warming became an alarming bell for the human society. So one has to think seriously about storing of available energy and retrieving it whenever required. Supercapacitor are receiving remarkable attention as an energy storage device, and being used various applications. Carbon based materials are widely used as electrodes in electrical double-layer capacitor (EDLCs). Supercapacitor performance is basically determined by the structural and electrochemical properties of electrodes. Various types of carbon materials like activated carbon (AC), carbon nanotubes, graphene were used as electrode material for EDLC, out of which activated carbon was found to be the cheapest material.
