Novel phase and phase transition behavior of a superionic conductor observed on the nanoscale
… and ion transport in a prototypical fast-ion conductor, copper selenide. Major objectives of my work were to elucidate i) the nature of the structural phase transition by which copper selenide becomes a superionic phase and ii) the microscopic mechanisms of ionic motion in this material. My …

Electrochemical and structural properties of superionic conductors in aqueous electrolyte
… limited by high resistance from the membrane, a superionic conductor. This thesis investigates the electrochemical and structural properties of these superionic conductors (NaSICON and LiSICON) in aqueous electrolyte of varying pH to determine its suitability for this new battery chemistry. The …

Raman scattering studies in the isostructural family of the solid electrolyte rubidium silver iodide
A solid electrolyte or superionic conductor has an ionic conductivity comparable to that of a molten salt or liquid electrolyte solution. The high ionic conductivity of, say, MAg I 4s (M=Rb,NH,K) results from a first order phase transition, Tl' 4 (T= l22K for M=Rb) whereby the Ag+ ions become …

Microporous materials fabricated from discrete molecular cages
… of 0.16 eV, this composite is characterized as a superionic conductor. Furthermore, the SLEN displays excellent oxidative stability up to 4.7 V vs. Li/Li+. This simple three-component system enables the rational design of electrolytes from tunable, discrete molecular architectures that possess …
