The catalytic dehydrogenation of LiBH(4) doped with exceptionally low quantities of carbon-supported Pt nanoparticles can be improved significantly, and smaller Pt nanoparticles result in greater enhanced catalytic dehydrogenation of LiBH(4) than do larger Pt nanoparticles.

While lithium borohydride is one of the most promising hydrogen storage materials due to its ultrahigh hydrogen storage density, high thermodynamic stability, kinetic barriers, and poor reversibility, it is far from being used in practical applications. Herein, we prepare a cubic hollow carbon dodecahedron uniformly modified with a bimetallic CoNi alloy (CoNi/NC) for preserving the stable catalytic effect of CoNi alloys toward reversible hydrogen storage. It is theoretically confirmed that bimetallic CoNi alloys effectively weaken the B-H bonds of LiBH by extending their average length to 1.

A mesoporous NiCoO urchin-like structure was synthesized by applying a facile hydrothermal method. Different concentrations of NiCoO urchin-like structures were mixed with a surface oxidized LiBH system using a wet-impregnation method, followed by heat treatment. The hydrogen storage capacity of LiBH + 25% NiCoO, LiBH + 50% NiCoO and LiBH + 75% NiCoO systems was investigated.

Nanostructured metal hydrides with unique morphology and improved hydrogen storage properties have attracted intense interests. However, the study of the growth process of highly active borohydrides remains challenging. Herein, for the first time the synthesis of LiBH nanorods through a hydrogen-assisted one-pot solvothermal reaction is reported.

LiBH is a promising solid-state electrolyte (SE) due to its thermodynamic stability to Li. However, poor Li-ion conductivities at room temperature, low oxidative stabilities, and severe dendrite growth hamper its application. In this work, a partial dehydrogenation strategy is adopted to in situ generate an electronic blocking layer dispersed of LiH, addressing the above three issues simultaneously.
