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 °C from the cobalt‐catalyzed Ca(BH 4 ) 2 –4 LiNH 2 system.
