Abstract (300 words maximum)
Energy storage systems such as ultracapacitors (UCs) have gained popularity due to their combination of high power density and long cycle life. The ability of UCs is to store charges electrostatically which results in much faster charging and discharging times, unlike other systems such as batteries. UCs are comprised of two electrodes that sandwiches a porous separator. Factors such as electrical conductivity, surface area, stability, and cost play important roles in materials selection. Carbon based materials such as activated carbon, graphene and carbon nanotubes are used due to high electrical conductivity and surface area, while metal oxides and conducting polymers are used due to their high capacitance and stability. In this research, electrodes prepared using conducting polymer, polypyrrole (PPy) is electrochemically deposited to determine the optimal performance of energy storage density. The UCs performance is measured using various techniques such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), as well as surface and chemical characterizations. UCs are ideally suited for applications such as electric vehicles, renewable energy storage, and electronics.
