Hydrogen storage properties of Ca(BH4)2-LiNH2 system.
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.
