Poster: Coarse-Grained Modeling of Ionic Liquid Crystals

Solid-state electrolytes are hypothesized to be a safe alternative to liquid electrolytes currently used in lithium-ion batteries, which can simultaneously meet the growing consumer demand for energy-storage. The best mechanisms for incorporating the solid state are a matter of significant research. Polymer based electrolytes have received significant attention for their mechanical stability, but often exhibit low conductivities which limits their technological impact. Partially ordered ionic liquid crystals could improve the ionic conductivity by allowing the dissociated ions to migrate within charge-rich layered domains. This work focuses on developing a physics-based coarse-grained model of ionic liquid crystals as a means to assess this hypothesis and the feasibility of these materials for energy storage. In particular, we will explore the limits of phase behavior, influence of the phase on conductivity, and the influence of added solvent in facilitating ion motion.
