A study of the LiNH2–MgH2 system for solid state hydrogen storage

Synthesis and crystal structure of a novel nitride hydride Sr2LiNH2

“…4, which is built up from [Sr 5 Li] octahedra. Similar to the Sr 2 ZnN 2 structure Table 1 Atomic coordinates, isotropic thermal parameters and occupation numbers for Sr2LiNH2 refined from X-ray powder diffraction data.…”

“…In order to improve the thermodynamic properties of binary Li-N-H system, Li was compositionally substituted by other elements, and several types of ternary or multinary metal-N-H systems (e.g. Li-Mg-N-H [5][6][7][8][9], Li-Ca-N-H [10,11], Li-Al-N-H [12][13][14], Li-B-N-H [12,15], Li-Co-N-H [16] and Li-Mg-Al-N-H [17,18]) were developed.…”

“…One is investigating the hydrogen absorption/desorption property [1][2][3][4][5][8][9][10][11][12][13][14][15][16][17][18]; the other is revealing the reaction mechanism involved in the hydrogen absorption/desorption processes [1,6,7,[14][15][16]21]. It was reported that the new ternary imides with mixed alkali and alkaline earth cations, Li 2 Mg(NH) 2 and Li 2 Ca(NH) 2 , were formed along with the dehydrogenation reaction in the Li-Mg-N-H and Li-Ca-N-H systems, respectively [5,8,11,[19][20][21]. The synthetic route involving the reac- * Corresponding author.…”

Structural and hydriding/dehydriding properties of Mg–La–Ni-based composites

“…By adjusting the chemical compositions of the Mg-based alloys, enhanced hydrogen storage properties have been obtained. These studies include multi-alloying of Mg with other elements [10][11][12][13][14][15][16][17], adding catalysts to the alloys [18][19][20][21] and preparing Mg-based composites like Mg-TiZrMnVFeNi [22], Mg-MmNi 5 [23], Mg-ZrMn 2 [24], Mg-NiCo 2 O 4 [25], Mg-LiNH 2 [26], Mg-TiB 2 [27], Mg-TiVMn [28], and so on.…”

Acceptability envelope for metal hydride-based hydrogen storage systems

“…In particular, the value of heat of reaction (assumed equal to 40 kJ/molH 2 for both BC and GA material) has been taken from [26], weight fraction wf (4.5% for BC material and 4.1% for GA material) from [27]. Thermal conductivity and density have been assumed to have the same values (BC and GA materials) as those for NaAlH 4 materials.…”
