Facilitation of quasi-reversible effect with rapid diffusion kinetics on Mg0.9-xTi0.1Nix high energy ball milled powders for Ni-MH batteries

Hydrogen storage properties of magnesium based alloys Mg67Ni(32-x)Nb1Alx (x = 1, 3, and 5) by using response surface methodology

“…Researchers are increasingly interested in metal hydride technology because it is the least harmful and simplest method [7,8]. Since 1970, Mg 2 Ni-based alloys have shown more significant interest in hydrogen capacity compared to other alloys due to their novel properties, such as lightweight construction, high reversibility, and abundance [9][10][11]. The addition of alloying elements (Nb, Al, Cr, Cu, Ti and Fe) to Mg 2 Ni leads to improved hydrogen storage capacity [12][13][14][15].…”

Mechanical alloying of Mg0.8-XTi0.2 and study the effect of adding (x = 0.2 wt%) transition metal like Sc, Zr, or Nb on their phase transitions, activation energy, and hydrogen storage properties

“…[15][16][17][18] The A 2 B 7 type Pr-Mg-Ni based alloy electrodes result in a maximum discharge capacity of 370 mA h g −1 , a high ex-change ion current density of 653 mA g −1 , and a high diffusion coefficient of 7.6 × 10 −9 cm 2 s −1 . 19 The maximum discharge capacity of AB 5 type compound is 300 mA h g −1 . 20 Compared to AB 2 , AB 5, and A 2 B 7 alloys, nanostructured Mg-Ti alloys are extensively used in hydrogen storage applications.…”

Activation energy study on nanostructured niobium substituted Mg2Ni intermetallic alloy for hydrogen storage application

“…This technology gives more benefits like high hydrogen absorption/desorption kinetics, long-term cyclic stability, and low cost [11][12][13]. In the past few decades, magnesium-based alloys have had an important role in hydrogen storage applications as they are abundant, lightweight, and have high reversibility [14][15][16]. However, pure magnesium has poor hydriding-dehydriding in alkaline solution, to solve these issues appropriate nanostructured transition metals are used to enhance the absorption/desorption kinetics of the hydrogen [17,18].…”
