Study of the composition dependence of the ionic conductivity of LiH_{x}D_{1-x} alloys

Abstract

Recent observations have shown that at a certain composition of solid solutions AgCl$_x$Br$_{1-x}$, AgCl-CdCl$_2$, AgBr-CdBr$_2$, of ionic crystals, the electrical conductivity exhibits a value appreciably larger than that of the end constituents. Here, we investigate the electrical conductivity $\sigma$ of LiH$_x$D$_{1-x}$ solid solutions -which are of prominent importance in fuel hydrogen storage applications- and find that in the whole composition range no maximum is likely to occur in the $\sigma$ versus x dependence.
