Electrolytes in Confinement by Conductive Surfaces

ORAL

Abstract

Electrolytes in confinement near conductive surfaces are present in numerous applications including energy storage, sensors, and nanofluidic devices, thereby understanding electrostatic interactions near conductive interfaces is of prime importance. We investigate an electrolyte solution confined by two multilayered graphene surfaces. We discuss the effect of graphene being a conductor on the electrolyte structure, ion-ion interactions, and dielectric properties of the confined electrolyte.
