Abstract: Laves phase-related BCC metal hydride alloys historically have limited electrochemical capabilities. Provided are processes of activating these alloys to produce hydrogen storage materials with greater than 200 mAh/g capacities and commonly much greater than 300 mAh/g capacities. The processes include cooling the alloy during hydrogenation to reduced temperatures or by subjecting the materials to significantly increased hydrogen pressures. Temperatures in many embodiments do not exceed 300° C. By decreasing the temperature or increasing the hydrogen pressure the phase structure of the material is optimized to increase a synergistic effect between multiple phases in the resulting alloy thereby greatly improving the electrochemical capacities.

Abstract: Rechargeable metal hydride alkaline cells are provided improved cycle life, lower internal resistance and enhanced utilization of energy by employing a positive electrode prepared by a method comprising applying a paste comprising an active positive electrode composition to a conductive substrate and exposing the pasted electrode to elevated temperature for a desired time period. The electrode composition comprises a particulate positive electrode active material, a polymeric binder and optionally one or more additives. The electrode active material is for instance nickel hydroxide or modified nickel hydroxide. In the case of a nickel foam substrate, the electrode composition may contain no binder.

Abstract: 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%.
