Liquid battery electrolytes have long been described as if they were simple recipes: a salt dissolved in a solvent, perhaps combined with an additive and adjusted to a specific concentration. Diffusion describes how particles move over relatively longer distances, but battery electrolytes also undergo local exchange, molecular rotation, ion hopping, and short-range rearrangement. Combining these measurements with molecular simulations and artificial-intelligence-based analysis could reveal connections between local liquid structure and measurable battery outcomes. Subject of Research: Liquid battery electrolytes, their microscopic structure, motion, and dynamic heterogeneity, studied using nuclear magnetic resonance (NMR).
