Hydrogen desorption and absorption for activated magnesium hydride
The interaction between MgH2 and LiBH4 was studied to determine the resultant effects on hydrogen desorption and absorption kinetics for potential use as a hydrogen storage material. It is found that the addition of LiBH4 in small molar ratios results in improved kinetics of the same order as those …

Destabilization of lithium borohydride with additions of magnesium hydride
… from MgH2 (275 - 350°C) then secondly from LiBH4 (315 - 450°C). The desorption temperature was found to increase with increasing amounts of LiBH4. No MgB2 or LiH was detected in the desorption products of samples dehydrogenated up to 450°C under 3 bar of flowing Ar but evidence for a Li – Mg …

A comparison of conventional heating techniques and microwave irradiation for the desorption of lithium borohydride and lithium borohydride composites
… heating techniques and microwave irradiation. LiBH4 was milled with TiH2 in various molar ratios in an argon atmosphere using both roller and planetary mill techniques. Thermo-gravimetric analysis and differential scanning calorimetry determined the desorption characteristics of the as received …

Beiträge zur Chemie von Hydroboraten BHnX4-n - (n = 1-4) des Lithiums, Natriums, Kaliums und Magnesiums
… Zusammensetzung der Verbindung im Vergleich zu LiBH4ž3 py (1) nicht. Das Tetrahydroborat zeigt m2- oder m3-Koordination zum Lithiumion. Bei einfacher ortho-Substitution der Pyridinringe wird eine Verbindung der Zusammensetzung (LiBH4ž2 L)2 erhalten, in der das Tetrahydroborat über ein 2m1 1, m1 …

Low-temperature protonation studies of transition metal alkyl complexes and the synthesis and characterization of early transition metal PCP pincer complexes and two-coordinate alkylamido complexes
… developed. The titanium compound reacts with LiBH4 to afford (tBuPCP)Ti(BH4)2. (tBuPCP)CrCl2(THF) can be desolvated to afford (tBuPCP)CrCl2 by application of heat under vacuum. (tBuPCP)CrCl2 undergoes reduction and decomposition when treated with LiBH4 but affords the chromium(II) product …

Direct 3D and in situ characterization of light metal hydrides for hydrogen storage
… during hydrogen cycling. The nano-confinement of LiBH4 in highly ordered mesoporous carbon scaffolds significantly reduces the high pressures and temperatures needed for de/rehydrogenation, but exhibits reduced practical loading limits and a degradation of hydrogen storage capacity with cycling. …

Investigation of electrochemical interfaces at the molecular level
… MgCl2+AlCl3/THF, and Mg(BH4)2+LiBH4/diglyme. Each of these electrolytes exhibits common surface stress response features, indicating that the mechanisms of Mg deposition and stripping are similar among the different electrolytes. Combining the measurements with density …

High coordination number compounds of thorium borohydride, and of calcium and strontium N,N-dimethylaminodiboranates
… The reaction of ThCl4 with six equiv. of LiBH4 in diethyl ether produces the compound [Li(Et2O)2][Th(BH4)5], the thorium center in this molecule is surrounded by six borohydride ligands. Four of these six borohydrides are coordinated in a tridentate κ3 fashion, and the other two BH4- …
