Hydrogen storage material based on LaNi5 alloy produced by mechanical alloying

Synthesis of Metal Hydrides by Mechanical Alloying in an Attritor Mill: Fy07 Status Report

“…Several technical reports and patents concerning the science of mechanical alloying 4,5 and, more specifically, forming LaNi 5 -based alloys by mechanical alloying [6][7][8][9] were reviewed prior to initiating this experimental program. Most of the mechanical alloying development work to form compounds similar to LaNi 4.25 Al 0.75 was performed in small-scale, high-energy mills.…”

Parameters of Synthesis of two Fold Materials for Application in Thermal Compression and Gross Purification of Hydrogen

“…Given the necessity to obtain these materials on a large scale and economically, the mechanical alloying is an appropriate method of both rapid synthesis and convenient cost compared to methods of synthesis of high temperature and more technological requirements, Liang et al (2001), Simičić et al (2001), Jurczyk et al: (2002, Rodriguez (2009), Obregón et al (2012). The inherent characteristics of AB5-type materials make them suitable for two stages of hydrogen technology: a) Thermal compression of hydrogen: the study of these materials applied to this stage focuses the analysis on the crystallographic and structural properties as a function of different types of substitution in the A and B sites of the intermetallic.…”

The hydrogen evolution reaction during charging for Ti–Zr–V–Ni–Cr alloy electrode

“…AB 5 type of hydrogen storage alloys has firstly received an extensive application in commercial Ni-MH battery and its practical reversible capacity can reach 280-320 mA h/g [2][3][4]. AB 2 Laves phase alloys have attracted extensive attention due to its low cost and excellent gaseous hydriding/dehydriding characters [5][6][7][8][9][10][11][12][13][14][15].…”
