Description
Summary:Li ion distribution in the crystal structure and the ionic conductivity of title superionic conductor are studied by NMR, impedance spectroscopy, and DTA. Two phase transitions are observed at 380 and 420 K, where a redistribution of Li sup + ions takes place. Li NMR spectra and spin-lattice relaxation indicate the presence of Li sup + -Li sup + contact pairs in the crystal lattice. A model for Li sup + transport is proposed.
