Abstract
A composite solid electrolyte of the LiBr·H 2OAl 2O 3 system was studied by means of the 7Li spin-lattice relaxation time. Two kinds of Li were observed in it; one of them has the same T 1 values as pure LiBr·H 2O with an activation energy of 52 kJ mol −1 for the Li +-ion self diffusion. The other showed a different temperature behaviour from LiBr·H 2O with respect to the phase transitions, suggesting formation of a new compound in the composite electrolyte. Judging from its activation energy of 18 kJ mol −1, this compound should be responsible for the enhancement of the ionic conductivity. The thickness of the highly conductive layer was estimated from a ratio of the NMR signal intensity applied to the preconceived model. Its composition dependence explains the composition dependence of the enhancement effect.
