A new strategy of quenching the first-step dehydrogenation of LiBH4–LiAlH4 composite (T = 220 °C) and particle size reduction via ball milling, leading to good dispersion of all species especially Al, is proposed for the first time. Additionally, multi-walled carbon nanotubes (MWCNTs) are ...

Moreover, decomposition of NaBH4 in nanoconfined sample can be done at 360 degrees C (dehydrogenation temperature in this study), which is 115 and 180 degrees C lower than that of NaBH4 in milled LiBH4-MgH2-NaAlH4 and bulk NaBH4, respectively. The reaction of LiBH4+NaAlH4 -> LiAlH4+...
Dehydrogenation kinetics and reversibility of LiAlH4-LiBH4 doped with Ti-based additives (TiCl3 and Ti-isopropoxide), multiwall carbon nanotubes (MWCNT), and MWCNT impregnated with Ti-based additives are proposed. Reduction of dehydrogenation temperature as well as improvements of kinetics and ...
The reaction between LiBH4and NaAlH4during nanoconfinement produces LiAlH4and NaBH4. During dehydrogenation, an intermediate phase (LiNa2AlH6) is formed and it decomposes in the temperature range of 203–350°C. Moreover, significant reduction in decomposition temperature of NaBH4of s1@310 with ...
Reversibility•Kinetic improvement of LiAlH4-LiBH4 by doping with Ti-based additives and MWCNT.•Significant reduction of dehydrogenation temperature (ΔTup to 40°C).•Faster desorption of thermally stable phase of LiBH4 (from 2.7 to up to 4.7wt% H2).•Increase of H2 content reversible...
A simple solid-state pre-lithiation approach has been used to prepare in situ a Li3AlH6-Al nanocomposite via a short-circuit electrochemical reduction between LiAlH4 and Li [75]. This nanocomposite is formed of Al nanograins dispersed in an amorphous Li3AlH6 matrix. When tested as an anode ...
