Nuclear Magnetic Resonance Studies of Ion Motion in Solid Electrolytes. Annual Report, June 1, 1982-March 31, 1983

摘要

An extensive investigation of a number of Li-Na beta-alumina crystals was carried out. It was found that the reaction of beta-aluminas with water involves partial substitution of M exp + by H sub 3 O exp + (or H exp + ) and carbonation at the crystal surface; i.e., reaction of a hydroxide with CO sub 2 . NMR spin-lattice relaxation data have been collected over the 4.2-100 exp 0 K temperature interval at several frequencies for a number of beta-aluminas. Extensive efforts on the NMR investigation of lithium, proton, and deuteron nuclei in both normal and deuterated single crystals of lithium-iodide-monohydrate are reported. An extensive investigation of the thermodynamics and cation exchange properties of the AgI: Ag sub 2 O-B sub 2 O sub 3 glasses has been performed. Cation exchange techniques to produce new vitreous electrolytes were not successful. (ERA citation 08:031795)
