Abstract (300 words maximum)
Electrochemical capacitors also known as ultracapacitor is a potential technology for modern energy storage due to their high performance of charge capacity and fast charge-discharge rates. The superior performance of ultracapacitors will help to meet demands for energy systems in applications such as transportation. Ultracapacitor device consists of electrodes, a polymeric separator, and an electrolyte. Under the applied voltage, the migration of ions between two porous electrodes from the bulk of the electrolyte governs the performance of such devices. In this work, we present experimental research on the synthesis of different electrode materials using atomically thick graphene and conducting polymers. The role of electrolyte composition, duration of synthesis, and nanocomposite electrode materials are studied in this work. Experimental results from cyclic voltammetry, impedance spectroscopy, and charge-discharge cycles will be presented. Mechanisms of charge transfer under ultracapacitor operation and performance evaluations will be presented.
