• homogeneous air-sensitive thin films, characterized by using ellipsometry, grazing incidence X-ray diffraction (GIXRD), in situ quartz crystal microbalance, and scanning electron microscopy, was observed. Lithium hydride diffraction peaks have been observed in as-deposited films by GIXRD. X-ray photoelectron

• that the composition of the as-deposited films is pure LiH, since the reaction of H2O and BuLi classically produces LiOH, at least in the presence of water in excess. However, thermodynamic considerations demonstrate that in fact lithium hydride and the concomitant reaction byproduct butanol are more

• electrodes. MgH2 reacts with lithium ions in a reversible lithium-driven conversion reaction generating lithium hydride and magnesium metal: MgH2 + 2Li+ + 2e− Mg + 2LiH. Moreover, this conversion reaction is not restricted to MgH2. It can also be carried out with several different binary and ternary
