    摘要： The present invention provides novel active materials which reversibly store hydrogen under conditions which make them exceptionally well-suited for elecrochemical applications. These active materials have both novel compositions and structures. A first group of active material compositions incorporate the elements of titanium, vanadium, and nickel. A second group adds zirconium to the first group of active materials. A preferred third composition group adds chromium to the first group of active materials. These materials may be single or multiphase combinations of amorphous, microcrystalline, or polycrystalline structures. Preferably, these materials have a multiphase polycrystalline structure. Methods of reducing the size or of sizing these materials, as well as other hydride-forming alloys, also are provided. Methods of preparing the inventive hydrogen storage materials and fabricating electrodes from these active materials are contemplated. Electrochemical cells and batteries assembled with the inventive electrodes provide significantly improved capacity and cycle life.

    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%.
