Advances in energy storage devices are required for the widespread implementation of intermittent renewable electricity generation technologies such as photovoltaics and wind power.  In addition, electrification of transportation will allow for the substitution of liquid fossil fuel energy with renewably sourced energy.  Energy storage platforms based on more abundant resources are essential for sustainable solutions.  High energy density storage devices with enhanced safety are also needed.  In this talk, I will discuss our research on polymers for next generation energy storage devices.  Topics will include the ion transport mechanisms in new types of single-ion conducting polymer electrolytes, ion transport in multivalent cation polymer electrolytes, and the mechanisms for reduced polysulfide crossover when employing ionomeric membranes in rechargeable metal-sulfur batteries.  Characterization methods used to study the material structure and dynamics include dielectric spectroscopy, Raman spectroscopy, UV-visible spectroscopy, and X-ray scattering.
