Two classes of novel structured electrolytes for advanced electrochemical energy storage systems are discussed. The first, in collaboration with colleagues at the University of Tennessee/Knoxville, is in the class of Deep Eutectic Solvents, using the Glycerol-Choline Chloride system as a model, and the second, in collaboration with colleagues at Columbia University, is in the class of Nanoparticle Organic Hybrid Materials. We employ Fast Field Cycling (FFC) NMR Relaxometry to obtain spin-lattice relaxation rates over three decades of frequency to yield information ranging from molecular rotation to translational diffusion. Supporting information from standard NMR pulsed field gradient diffusion measurements is used to validate the FFC analysis.
