Cho, YW Shim, JH Lee, BJ 2024-01-21T03:34:42Z 2024-01-21T03:34:42Z 2021-09-02 2006-03 0364-5916 https://pubs.kist.re.kr/handle/201004/135697 Some alkali and alkali-earth metal hydrides and their complex hydrides have very high hydrogen storage capacities and reversibility. Unfortunately, most of them have decomposition temperatures that are too high. This must be overcome before these hydrides can be considered seriously as practical hydrogen storage materials for on-board applications. In the present study, the CALPHAD approach has been adopted to evaluate thermodynamically the possibility of destabilizing these high temperature binary ionic hydrides and ternary complex hydrides by reacting them with light elements or other hydrides. The MgH2 + Si, LiBH4 + MgH2, and LiBH4 +Al systerns are predicted to show a significant decrease in decomposition temperature. On the other hand, the decrease in the decomposition temperatures of the MgH2 + Al and NaBH4 + Al systems is relatively small. The LiH + Si system also presents a considerable destabilization effect, which is consistent with experiment. (c) 2005 Elsevier Ltd. All rights reserved.
