  • ALLOY POWDER FOR ELECTRODES, NEGATIVE ELECTRODE FOR NICKEL-HYDROGEN STORAGE BATTERIES USING SAME AND NICKEL-HYDROGEN STORAGE BATTERY
    Publication number: 20180019469
    Abstract: Alloy powder for electrodes that includes particles of a hydrogen-absorbing alloy having an AB2 type crystal structure. The hydrogen-absorbing alloy includes first elements that are located in an A site in the crystal structure and include Zr, and second elements that are located in a B site and include Ni and. Mn. The hydrogen-absorbing alloy includes a plurality of alloy phases having different Zr concentrations. In each of the alloy phases, the percentage of Zr in the first elements exceeds 70 atom %.

  • Alloy powder for electrode and method for producing same
    Patent number: 8137839
    Abstract: An electrode alloy powder includes a hydrogen storage alloy and magnetic material clusters. The hydrogen storage alloy contains 20 to 70 wt % of Ni. The magnetic material clusters contain metal nickel, and have an average cluster size of 8 to 10 nm. A method for producing the electrode alloy powder includes an activation step of allowing a raw material powder including a hydrogen storage alloy to be in contact with an aqueous solution containing A wt % of sodium hydroxide and held at 100° C. or greater for B minutes. A and B satisfy 2410?A×B?2800.
    Type: Grant
