Description
Summary: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 just been published by Hoang and Van de Walle [Solid State Ionics 253 (2013) 53–56]. Their results are found here to be of key-importance to deduce useful results for the pressure dependence of the ionic conductivity of LiH. •Thermodynamic aspects of ionic conductivity in LiH•Ionic conductivity in LiH is likely to increase upon increasing hydrostatic pressure.•Calculation of the activation volume of Schottky pairs in LiH based on cBΩ model.
