And when heated to around 80 degrees Celsius they discharge their hydrogen content in just a few minutes, overcoming the problem of conventional hydrides
, that release their hydrogen content very slowly, over around 30 to 60 minutes, making them unsuitable for use in cars.
The XRD results also show that, after hydrogenation sharpness of the Mg-Fe hydride
peaks increased, with the insertion of hydrogen atom, the surface lattice volume of the compound is increased.

materials for solid hydrogen storage: a review," International Journal of Hydrogen Energy, vol.
nucleation takes place at the end of flakes including grain boundaries.
In the chromosphere, the interaction between the helium hydride
ion, He[H.sup.+], and condensed hydrogen structures, CHS , could lead to an array of reactions as outlined in Fig.
The three companies will begin detailed discussion toward the reuse in motors and begin the process as soon as a sufficient volume of used nickel-metal hydride
batteries is secured.
As much as 80 percent of the rare earth metals in used nickel-metal hydride
batteries can be extracted with this new process, the automaker said.
Both firms will start extracting rare earth metals from used nickel-metal hydride
batteries collected from Honda's hybrid vehicles at Honda dealerships.
In this study, sodium alanate, purchased from Sigma Aldrich, was selected as a model complex hydride
in order to illustrate the filling feasibility.
Zirconium phase has a very low solubility of hydrogen, resulting in any excess hydrogen getting precipitated as zirconium hydride
. This leads to embrittlement , delayed hydride
cracking (DHC) and hydride
blistering, all of which limit the lifetime of reactors and cause serious safety and environmental concerns.
The company has been supplying nickel-metal hydride
batteries for hybrid electric vehicles (HEVs) to Honda and Ford since 2004.
