Abstract (300 words maximum)
In this work, graphene will be integrated into polypyrrole (PPy) polymer matrices to form Graphene-PPy (GrPPy) nanocomposites. The GrPPy nanocomposites will be synthesized and investigated for their use in ultracapacitor devices as electrodes. We hypothesize that due to graphene’s electrochemical properties and high surface area, that the composites will provide superior energy storage performance.GrPPy nanocomposites will be synthesized using an electrochemical deposition and the performance will be evaluated using various electrochemical studies in the presence of various aqueous electrolytes. Distinct Faradaic and non-Faradaic charge transfer mechanisms will be investigated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge (GCD) studies. The results of various experiments, including different percentages of dopants and their effect on ultracapacitor performance will be presented. Lifecycle testing of the devices will be presented. The role of different aqueous electrolytes and their effect on performance will be discussed. Ion transfer between the electrolyte and GrPPy surface will be presented.
