Lithium borohydride (LiBH 4) is a borohydride and known in organic synthesis as a reducing agent for esters. Although less common than the related sodium borohydride, the lithium salt offers some advantages, being a stronger reducing agent and highly soluble in ethers, whilst remaining safer to handle than lithium aluminium hydride.

The hydrogen dynamics in solid and in liquid LiBH4 was studied by means of incoherent quasielastic neutron scattering. Rotational jump diffusion of the BH4- subunits on the picosecond scale was observed in solid LiBH4. The characteristic time constant is significantly

Here we show that a chemical modification of LiBH 4 can stabilize the superionic phase even below room temperature. By doping of lithium halides, high conductivity can be obtained at room temperature. Both XRD and NMR confirmed room-temperature stabilization of superionic phase for LiI-doped LiBH 4.

2024年10月5日 · Among the many hydrogen storage materials, lithium borohydride has a good development prospect due to its high hydrogen storage capacity. This manuscript presents a thorough examination of the advantages and drawbacks associated with lithium borohydride as a hydrogen storage medium.

LiBH4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a 5-coordinate geometry to five H+0.50+ atoms. There are a spread of Li–H bond distances ranging from 1.98–2.14 Å. B3- is bonded in a tetrahedral geometry to four H+0.50+ atoms.

2020年4月30日 · LiBH4 is a promising material for hydrogen storage and as a solid-state electrolyte for Li ion batteries. Confining LiBH4 in porous scaffolds improves its hydrogen desorption kinetics, reversibility, and Li+ cond., but little is known about the influence of the chem. nature of the scaffold.

2014年10月22日 · LiBH 4 is a promising solid electrolyte for Li-ion batteries. It displays high lithium mobility, although only above 110 °C at which a transition to a high temperature hexagonal structure occurs.

2011年11月1日 · In this paper, we reviewed the recent progress in LiBH 4, including the synthesis, hydrolysis, structure, dynamics, and intermediate compounds of LiBH 4. The desorption of hydrogen of LiBH 4 need harsh conditions. There are several methods to improve the de/rehydrogenation properties of LiBH 4. The first method is “destabilization” of the LiBH 4.
