Abstract

A first-principle study of the formation and migration of native defects in LiH, a material of interest in hydrogen storage and lithium-ion batteries, has recently been published. Their results are found here to be of key-importance to deduce useful results for the pressure dependence of the ionic conductivity of LiH.
