A common component of next-generation electrical energy storage and delivery devices (batteries, capacitors, fuel cells) is typically a charged species (ion, electron) moving through an electrolyte (solid or liquid) media. To balance the charge of the particles, the electrolyte itself typically contains counter charges. The charged particle moves through the electrolyte via a hopping process, moving from one counter charge location to the next. This research project focuses on developing measurement methods that correlate the intrinsic molecular mobility in the electrolyte material to the kinetics of the charged particle transport. Our goal is to understand the dynamic coupling between the host and the charged particle transport. Experimental techniques of particular interest include inelastic neutron scattering, low frequency Raman scattering, dielectric or impedance spectroscopy, and molecular modeling.
