Abstract:
Complex hydrides, such as LiBH4, are a promising class of ion conductors for all-solid-state batteries, but their application is constrained by low ion mobility at room temperature. Mixing with halides or complex hydride anions, i.e., other complex hydrides, is an effective approach to improving the ionic conductivity. In the present study, we report on the reaction of LiBH4 with LiBF4, resulting in the formation of conductive composites consisting of LiBH4, LiF and lithium closo-borates. It is believed that the in-situ formation of closo-borate related species gives rise to highly conductive

Abstract:
A wet loading method was developed to produce nano-sized LiBH4 combined with nano-SiO2 templates. The multicomponent LiBH4/SiO2 material synthesized by the wet method has been found to dehydrogenate at much lower temperatures than the pure LiBH4, as well as LiBH4/SiO2 mixtures prepared by ball milling. For example, the onset of dehydrogenation was decreased to about 200 °C for a wet-treated LiBH4/SiO2 mixture with a mass ratio of 1:1, and the majority of the hydrogen could be released below 350 °C. The improved dehydrogenation of the wet-treated LiBH4/SiO2 mixtures can be attributed to the des

Abstract:
LiBH4 has high hydrogen storage capacity, and its high gravimetric hydrogen density reaches 18.36%. However, LiBH4 exhibits poor hydrolysis performance in water because the abrupt ending caused by the agglomeration of its hydrolysis products limits its full utilization [1, 2]. In this paper, four kinds of organics, namely, ethanol, tetrahydrofuran, acetic acid, and butanol (referred to MOH) were added to water, and the effect of MOH species and amount on the hydrolysis performances of LiBH4 was evaluated. Results show that agglomeration can be avoided and that LiBH4 has a controllable hydrogen

Abstract:
Approximately 6.3 wt.% of hydrogen is released from a LiBH4–0.25TiF4 combination below 150°C. Hydrogen desorption from the LiBH4–0.25TiF4 combination undergoes a quite different reaction process with respect to the LiBH4–0.33TiF3 mixture due to the higher oxidation state of Ti4+ and the lower mean bond cleavage energy of Ti–F bonds in TiF4 . This finding provides a viable approach for significantly decreasing the dehydrogenation temperature of LiBH4 by optimizing the additives with high oxidation valency.

Adding a secondary complex metal hydride can either kinetically or thermodynamically facilitate dehydrogenation reactions.

Samples of the LiBH4 and Mg2FeH6 with a 2:1 molar ratio were mixed and decomposed under three different conditions (dynamic decomposition under vacuum, dynamic decomposition under a hydrogen atmosphere, and isothermal decomposition).

Abstract:
Abstract The hexagonal high-temperature form of LiBH4 is known as a fast ion conductor. Here, we investigated its suitability as a solid electrolyte in high-temperature all-solid-state cells when combined with the following active materials: Li metal, graphite, lithium titanium oxide (Li4Ti5O12, LTO), and nanocrystalline rutile (TiO2). First results using lithium anodes and rutile nanorods as cathode material show that a cell constructed by simple cold-pressing operates at reversible discharge capacities in the order of 125 mA h g−1 at a C-rate of C/5 and at temperatures as high as 393 K.

Abstract:
Mge10 mol% LiBH4 composite plus small amounts of FeF3 is investigated in the present work. The presence of LiBH4 during the milling process noticeably modifies the size and morphology of the Mg agglomerates, leading to faster hydrogenation and reaching almost the theoretical hydrogen capacity owing to enhanced hydrogen diffusion mechanism. However, the dehydrogenation of the system at low temperatures (about 300 ºC) is still slow. Thus, FeF3 addition is proposed to improve the dehydrogenation kinetic behavior. From experimental results, it is found that the presence of FeF3 results in an

Abstract:
The investigations based on kinetic improvement and reaction mechanisms during melt infiltration, dehydrogenation, and rehydrogenation of nanoconfined 2LiBH4–MgH2–0.13TiCl4 in carbon aerogel scaffold (CAS) are proposed. It is found that TiCl4 and LiBH4 are successfully nanoconfined in CAS, while MgH2 proceeds partially. In the same temperature (25–500 C) and time (0–5 h at constant temperature) ranges nanoconfined 2LiBH4–MgH2–0.13TiCl4 dehydrogenates completely 99% of theoretical H2 storage capacity, while that of nanoconfined 2LiBH4–MgH2 is only 94%.

Abstract:
AbstractIn contrast to the traditional metal hydrides, in which hydrogen storage involves the reversible hydrogen entering/exiting of the host hydride lattice, LiBH4 releases hydrogen via decomposition that produces segregated LiH and amorphous B phases. This is obviously the reason why lithium borohydride applications in fuel cells so far meet only one requirement — high hydrogen storage capacity. Nevertheless, its thermodynamics and kinetics studies are very active today and efficient ways to meet fuel cell requirements might be done through lowering the temperature for hydrogenation/dehydro

Abstract:
Nitrogen-doped ordered mesoporous carbon has been synthesized and used to confine LiBH4 to improve its dehydrogenation properties. The carbon has a high BET specific surface up to 448.25 m2/g with pore size centered at 1.2 and 4.1 nm. The effects of ball milling time and speed on de-hydrogenation were investigated. The onset hydrogen desorption temperature of LiBH4 is reduced to 100 °C by addition 40 wt% carbon, and it can release hydrogen of 8.3 wt% at 380 °C. Furthermore, cyclic dehydrogenation is studiedto estimate the stability of the samples in the present work.

Incipient wetness impregnation was employed to decorate two N-doped graphene-rich matrixes with iron, nickel, cobalt, and copper nanoparticles. The N-doped matrix was wetted with methanol solutions of the corresponding nitrates. After agitation and solvent evaporation, reduction at 800 °C over the carbon matrix promoted the formation of nanoparticles. The mass of the metal fraction was limited to 5 wt. % to determine if limited quantities of metallic nanoparticles catalyze the hydrogen capture/release of nanoconfined LiBH4.

Both LiBH4 and NaBH4 are well known for having high hydrogen contents, but also high decomposition temperatures and slow hydrogen absorption–desorption kinetics, preventing their use for hydrogen storage applications. The low melting temperature (219 °C) of their eutectic mixture 0.71 LiBH4–0.29 NaBH4 allowed the synthesis of a new composite material through the melt infiltration of the hydrides into the ~5 nm diameter pores of a CMK-3 type carbon. A composite of 0.71 LiBH4–0.29 NaBH4 and non-porous graphitic carbon discs was also prepared by similar methods for comparison. Both composites sho

To enhance the dehydrogenation/rehydrogenation kinetic behavior of the LiBH4−MgH2 composite system, TiF4 is used as an additive. The effect of this additive on the hydride composite system has been studied by means of laboratory and advanced synchrotron techniques. Investigations on the synthesis and mechanism upon hydrogen interaction show that the addition of TiF4 to the LiBH4−MgH2 composite system during the milling procedure leads to the in situ formation of well-distributed nanosized TiB2 particles. These TiB2 nanoparticles act as nucleation agents for the formation of MgB2 up

In this study, lithium borohydride (LiBH4) reduction was used to modify the surface chemistry of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) fibers. Although the most common reaction employed in the surface treatment of polyester materials is hydrolysis, it is not suitable for fiber modification of bacterial polyesters, which are highly resistant to this type of reaction. The use of LiBH4 allowed the formation of surface hydroxyl groups under very mild conditions, which was crucial for maintaining the fibers’ integrity. The presence of these groups resulted in a noticeable improvement
