abstract = {This work begins with a discussion of the desorption,
reaction rate-limiting step of a LiNH2-LiH hydrogen storage
system. Using microstructural and thermodynamic studies, it
explains the working mechanism of BN as an additive in
Li-N-H hydrogen storage materials. High-energy wet ball
milling with THF was applied to the LiNH2 + 1.2LiH mixture.
The results obtained in this work show that the
rate-limiting step of the desorption reaction depends on the
degree of oxidation and amount of LiH in the system. The
activation energy of the desorption reaction of both
ball-milled LiNH2 and LiNH2 + 1.2LiH samples was reduced
with BN as an additive. BN had no clear impact on the
crystallite sizes of LiNH2 + 1.2LiH as-milled samples.
However, it was found that BN stabilizes the crystallite
sizes of LiNH2 + 1.2LiH samples during the high-temperature
desorption and absorption processes.},
