Abstract

Hydrogen vacancy effect on the activation energy for self-diffusion is investigated by NEB method. The path was calculated by moving a hydrogen atom from a nearby AlH4- complex into the vacancy in the AlH4- complex. Compared with the substitution enthalpy of hydrogen vacancy, the activation energy for self-diffusion is easier to achieve during the dehydrogenation process.
