“…(1), the calculated I 0 value of MgNi-NiB (344.80 mA g −1 ) is larger than that of MgNi (67.60 mA g −1 ), which indicates NiB improve the electrochemical hydrogen absorb/desorb kinetics of MgNi alloy in alkali solution. The I 0 values of MgNi-NiB are consistent with our previous work [8,9,11]. Table 3.…”

“…Shao et al fabricated a series of milling Mg-Ni system alloy and investigated the effect of microstructure on hydrogen storage properties, and concluded that the Mg 50 Ni 50 with BBC nanostructure showed more opportune absorpting/desorpting and kinetics performance, and the adding transition metal and its compound also improved the hydrogen storage properties [5]. Feng et al mechanically milled the Mg -Ni alloy with CoB for 15 h to display excellent electrochemical and kinetic characterization [6]. The addition of Pd nanoparticle in the process of fabricating MgNi alloy through applying ball -milled technology remarkably ameliorated the absorbing/desorbing hydrogen capacity and kinetics performance [7].…”

Abstract. The nanocrystalline and amorphous Mg x Ni 100-x +5wt.%TiF 3 (x=50, 60, 70) hydrogen storage alloys were synthesized by mechanical ball milling method. Microstructure and electrochemical performances of ball-milled alloys were characterized by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), electrochemical discharge capacity and cycling stability. The results show that the ball-milled hydrogen storage alloys hold a multiphase structure consisted of two main phases Mg 2 Ni and Ni as well as a small amount of third phase MgNi 2 and TiNi. The ball milling Mg 50 Ni 50 +5wt.%TiF 3 composite possesses optimal electrochemical discharge capacity, which is relevant to amorphous/nanocrystalline structure and hydride Mg 2 NiH 4 phase after absorbing hydrogen. X-ray diffraction analysis indicates that ball-milled Mg 50 Ni 50 +5wt.%TiF 3 composite exhibits the best electrochemical discharge properties.

“…They found that charge-transfer resistance increased with the depth of discharge (DOD) and the fitted charge-transfer resistance was larger than the corresponding Warburg impedance. By means of EIS, Yuan and coworkers studied Al and Ce [15], Ti-Al [16], CoB [17,18], NiB [19], FeB [20], and MB (M = Co, Ti) [21] substituted amorphous MgNi-based alloy electrodes. But most of their studies only focused on the discussion of the variation of charge-transfer resistance of different substituted alloys at 50% DOD.…”
