Abstract

This project addresses the development and investigation of both electrolyte and electrode components for energy storage applications. Molecular dynamics and DFT techniques are a powerful method for the development and study of new materials. Three distinct topics are proposed: one focuses on improving properties of electrolyte, as ionic liquids or aqueous electrolytes, by altering the composition, constituent ions, molar fractions, and aqueous and organic mixtures. A second one, focuses on increasing supercapacitor yield by employing 2D materials with exclusive properties to provide an enhanced electrode response. And a third, aim the computational investigation of the corrosion mechanism at the electrode-electrolyte interface, based on the voltage induced in different modified graphene electrodes. (AU)
