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.

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.

Based on our detailed analysis of the structure, energetics, and migration of lithium-, boron-, and hydrogen-related defects, we propose a specific mechanism for the decomposition and dehydroge-nation of LiBH4 that involves mass transport mediated by native defects.

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.

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.

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.

2020年6月1日 · State-of-the-art perspectives on tuning the stable thermodynamics and sluggish kinetics of dehydrogenation and re-hydrogenation of LiBH 4, which has been regarded as a promising hydrogen storage alternative for onboard energy carrier applications have …

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.

In this review, we focus on some of the main explored approaches to tune the thermodynamics and kinetics of LiBH 4: (I) LiBH 4 + MgH 2 destabilized system, (II) metal and metal hydride added LiBH 4, (III) destabilization of LiBH 4 by rare-earth metal hydrides, and (IV) the nanoconfinement of LiBH 4 and destabilized LiBH 4 hydride systems.

2024年12月6日 · This review critically analyzes recent advances in LiBH4 modification through three primary strategies: catalytic enhancement, nanostructure engineering, and reactive composite design.
