This paper presents a relationship
between ionic mobility and reaction
kinetics for the Li–N–H system after doping LiTi<sub>2</sub>O<sub>4</sub>. The structural characteristic of this fast
ionic conductor was introduced to the complex–hydride system.
On one hand, the properties of the dehydrogenation process were improved
significantly. On the other hand, the relationship between lithium
ionic conductivity and the catalytic effect on the dehydrogenation
was investigated according to the alternating current (AC) impedance
results. The lithium ionic conductivity of samples with catalyst was
higher than the samples without catalyst. Especially, the conductivity
of LiNH<sub>2</sub> and LiH mixtures with LiTi<sub>2</sub>O<sub>4</sub> was almost 1.5 times higher than that of LiNH<sub>2</sub> and LiH.
The mobility of the Li<sup>+</sup> ions between LiH and LiNH<sub>2</sub> solid phases was enhanced by adding LiTi<sub>2</sub>O<sub>4</sub>.
