Electrochemical hydrogen storage characteristics of Mg1.5Al0.5−xZrxNi (x=0, 0.1, 0.2, 0.3, 0.4, 0.5) alloys synthesized by mechanical alloying

Electrochemical hydrogen storage capacities of Mg2Ni and MgNi alloys synthesized by mechanical alloying

“…The XRD pattern of MgNi alloy also looks much smoother. All these observations suggests that while MgNi alloy is in fully amorphous characteristics, Mg 2 Ni alloy is probably composed of mixture of the nano-crystalline and amorphous structures [17]. Two sharp nickel peaks in the XRD pattern of MgNi alloy in Fig.…”

“…2a and b, respectively. The fragmentation of the coarse, cold-welded particles into the fine powders in the figures show the typical morphology of the amorphous-like alloys [17][18][19].…”

“…The poor hydriding/dehydriding kinetics at room temperature, however, hampers the practical applications of these alloys [5]. The intensive efforts have been spent to improve the kinetic properties [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The most significant improvement in the hydriding/dehydriding kinetics was realized with the synthesis of these alloys by the mechanical alloying [3][4][5][6][7][8].…”

“…hydrogen storage Mg alloys [9][10][11][12][13][14][15][16]. Recently we have reported the effects of Zr, Ti and Al replacement elements on the electrochemical hydrogen storage characteristics of Mg 2 Ni alloy synthesized by the mechanical alloying [17][18][19].…”

Effects of single- and co-substitution of Ti on dehydrogenation of Mg 2 NiH 4 : A first-principles study

“…To reduce the dehydrogenation enthalpy of Mg 2 NiH 4 , a substantial amount of compositional modifications have been carried out [9,[13][14][15][16][17][18][19][20][21]. Partial substitution of Mg with foreign elements is significantly effective for dehydrogenation of Mg 2 NiH 4 .…”
