Influences of fluorine containing compounds TiF4 and ZrF4 on hydrogen sorption properties of LiBH4 have been investigated. Thermovolumetric measurements, titration, and XRD technique were used to characterize the samples. The results demonstrated a pronounced beneficial effect of both ZrF4 and TiF4 on the sorption properties of modified LiBH4. After hydrogenation at 400°C and 80 bar, formation of modified LiBH4 was observed as a consequence of F dissolution in LiH (LiH1-zFz). Adding TiF4 and ZrF4 to LiBH4 has been found to modify both thermodynamic and kinetic properties.
