Title: Effects of Ti-Based Additives on the Hydrogen Storage Properties of a L i B H 4 / C a H 2 Destabilized System

Abstract

The hydrogen storage properties of a destabilized LiBH 4 / CaH 2 system ball-milled with TiCl 3 , TiF 3 , and TiO 2 additives have been investigated. It is found that the system with TiCl 3 additive has a lower dehydrogenation temperature than the ones with other additives. Further study shows that a higher amount of TiCl 3 is more effective in reducing the desorption temperature of the LiBH 4 / CaH 2 system, since it leads to a lower activation energy of dehydrogenation. The activations energies for mixtures containing 4, 10, and 25 mol% of TiCl 3 are 141, 126, and 110 kJ/mol, respectively. However, the benefits of higher amounts of TiCl 3 are offset by a larger reduction in hydrogen capacity of the mixtures.
