摘要/Abstract

摘要： In this work, the hydrogen sorption properties of the LiBH₄-Mg₂NiH₄ composite system with the molar ratio 2:2.5 were thoroughly investigated as a function of the applied temperature and hydrogen pressure. To the best of our knowledge, it has been possible to prove experimentally the mutual destabilization between LiBH₄ and Mg₂NiH₄. A detailed account of the kinetic and thermodynamic features of the dehydrogenation process is reported here.
