Abstract

The improvement of energy storage devices is always in development to ensure better systems to the needs in many areas, as portable electronics, electric vehicles and backup system in the electrical grid. The electrochemical capacitors (ECs) are part of the category of energy storage devices that present high-energy storage capability and quick release of this energy. The use of new materials can improve the energy and power of ECs. In case of electrodes, it is important to obtain materials which present high surface area to increase the electrode capacitance and in consequence, the energy. Still, in case of electrolyte, the increase in the working voltage will result in higher energy and power. Thus, the use of Graphene and nanostructured transition metal oxides as electrodes ensures the first requirement, and the use of ionic liquids (ILs) which present high electrochemical stability ensures the second requirement. With this in mind, it is important to determine how the synergy among these materials works in real ECs and the comparison with standard materials. (AU)
