Abstract:EDLC’s Electrochemical Double Layer Capacitor form excellent energy storage device for high power applications with added advantage of avoidance of electrolyte leaks, improved reliability and packaging to suit different applications, when we use a solid electrolyte. We can use activated carbon to Graphene, with varying particle size, surface area, pore size and pore distribution as the active material for charge storage. The emphasis is to optimize the Graphene to carbon blend in the electrodes which would enhance the storage density of the EDLC. We have used perflurosulfonic acid polymer as the solid electrolyte in the EDLC assembly. They have high ionic conductivity, good thermal stability, adequate mechanical strength and excellent chemical stability. Carbon is widely used for many practical applications, especially for the adsorption of ions and molecules, and because it is possible to synthesize one-, two-, or three-dimensional (1-, 2-, or 3-D) carbons. Some of the problems in activated carbon like varying micro or meso pores, poor ion mobility due to varying pore distribution, low electrical conductivity, can be circumvented by using Graphene and blends of Graphene with carbon of the right pore dimension.
