    摘要： A reversible hydrogen storage alloy capable of storing large amounts of hydrogen and delivering reversibly large amounts of hydrogen at temperatures ranging from 0° C. up to 40° C. The hydrogen storage alloy is generally composed of titanium, vanadium, and chromium. The alloy may further include manganese. Modifier elements such as zirconium, iron, nickel, molybdenum, ruthenium, and/or cobalt, and scavenger elements such as misch metal, calcium, and/or magnesium may be included in the alloy to improve performance.

    摘要： A hydrogen storage alloy having the atomic formula AB4.75-5.25. Where A may comprise at least 85 atomic percent Nd and less than 15 atomic percent other rare earth elements and Mg and B may comprise Ni, Co, and at least one element selected from the group consisting of Mn and Al. The atomic percentages of Mn and Al may be governed by the following formulas where Mn and Al are in atomic percent: 1) Mn+1.5 Al≧6 atomic percent; and 2) Mn+Al≦12 atomic percent. The total percent of Mn and Al may provide the alloy with a 20° C. plateau pressure of between 4 and 25 psi, preferably between 6 and 20 psi. The hydrogen storage alloy allows a nickel metal hydride battery into which it is incorporated to maintain a voltage of at least 1.2 V at a depth of discharge of 90%.
