Recent Development of Lithium Borohydride‐Based Materials for Hydrogen Storage

چکیده
Lithium borohydride (LiBH4) has been attracting extensive attention as an exemplary high-capacity complex hydride for solid-state hydrogen storage applications because of its high capacities (18.5 wt% and 121 kg H2 m−3). However, the strong highly directional covalent ionic bonds within LiBH4 structure induce desorption temperatures, slow kinetics, poor reversibility, which make large-scale application impractical. To improve cycling performance, several strategies including cation/anion substitution, catalyst doping, reactive compositing, nanoengineering, have developed to tailor thermodynamics kinetics process. For example, largely reduced operation temperatures remarkably improved reversibility under moderate conditions achieved by synergistic effect nanostructuring nanocatalysis. Herein, state-of-the-art development LiBH4-based materials is summarized, basic physical chemical properties, principles thermodynamic kinetic manipulation properties. The remaining challenges main directions future research are also discussed.

متن کاملPredicting New Materials for Hydrogen Storage Application
Knowledge about the ground-state crystal structure is a prerequisite for the rational understanding of solid-state properties of new materials. To act as an efficient energy carrier, hydrogen should be absorbed and desorbed in materials easily and in high quantities. Owing to the complexity in structural arrangements and difficulties involved in establishing hydrogen positions by x-ray diffract...
