Abstract

In mixture of LiI with γAl2O3 the ionic conductivity is found to increase by up to three orders of magnitude over pure LiI. NMR measurements of7Li relaxation times were performed on both anhydrous LiI and a mixture of LiI with 30m/o γAl2O3. The relaxation is found to be purely dipolar in origin for the pure halide with correlation times consistent with conductivity data. However two relaxation rates are found in the composite material which indicate that 50% of the7Li ions are in a radically different environment.
