title: Hydrogen storage properties of Ca(BH4)2-LiNH2 system.
abstract: Ca(BH(4))(2) is one of the promising candidates for hydrogen storage materials because of its high gravimetric and volumetric hydrogen capacity. However, its high dehydrogenation temperature and limited reversibility has been a hurdle for its practical applications. In an effort to overcome these barriers and to adjust the thermal stability, we make a composite system Ca(BH(4))(2)-LiNH(2). Interaction of Ca(BH(4))(2) and LiNH(2) leads to decreased dehydrogenation temperatures and increased hydrogen desorption capacity in comparison to pristine Ca(BH(4))(2). More than 7 wt% of hydrogen can be detached at a temperature as low as approximately 178 degrees C from the cobalt-catalyzed Ca(BH(4))(2)-4 LiNH(2) system.
