Title: Understanding Ion Transport in Single-Ion Conducting Solid Polymer Electrolytes

Understanding ion transport in polymer electrolytes is at the forefront of research with applications in energy storage, membranes, and transducers. In this talk, I will present progress made in understanding transport of lithium and sodium in single-ion conducting solid polymer electrolytes such as in polymerized ionic liquids and their blends. Starting from a summary of experimental results related to the temperature-dependent ionic conductivity, glass transition temperature, and local structure, I will present our efforts to develop a statistical mechanical theory for connecting local structure to the ionic conductivity. Results from coarse-grained molecular dynamics simulations and electronic density functional theory will be briefly discussed.
