Two effective methods, 1) substitution of M elements and 2) preparation of appropriate mixtures, for decreasing the dehydriding temperatures of M-N-H and M-B-H (M=Li, Mg) systems were briefly reviewed. The dehydriding reactions of LiNH2 and LiBH4 with/without Mg substitutions proved that the dehydriding temperatures become lower with the increasing Mg concentrations. Also, a mixture of Mg(NH2)2 and LiH, which was chosen as one of the best compositions with low dehydriding temperature among mixtures of M(NH2)x and MHy. Increasing the LiH ratio in the mixtures is one of the important techniques to prevent ammonia release. Moreover, the dehydriding temperature of LiBH4 was reduced by 150 K by mixing 2 M of LiNH2, suggests that the stabilities of the dehydriding reactions of complex hydrides can be controlled by introducing new pathways by mixing.
