Title: LaNi{sub 5}-based metal hydride electrode in Ni-MH rechargeable cells

Abstract

An at least ternary metal alloy of the formula AB{sub (Z-Y)}X{sub (Y)} is disclosed. In this formula, A is selected from the rare earth elements, B is selected from the elements of Groups 8, 9, and 10 of the Periodic Table of the Elements, and X includes at least one of the following: antimony, arsenic, germanium, tin or bismuth. Z is greater than or equal to 4.8 and less than or equal to 6.0. Y is greater than 0 and less than 1. Ternary or higher-order substitutions to the base AB{sub 5} alloys that form strong kinetic interactions with the predominant metals in the base metal hydride are used to form metal alloys with high structural integrity after multiple cycles of hydrogen sorption. 16 figs.

LaNi{sub 5{minus}x}M{sub x} metal hydride alloys for alkaline rechargeable cells

Conference Witham, C K; Hightower, A; Bowman, Jr, R C; ...

This work centers on making alloy modifications to LaNi{sub 5} by replacing Ni with various metal elements. The primary goal of the alloy modifications is to stabilize the alloy during electrochemical cycling in an alkaline medium. The reasons that some elements promote cyclic stability are explored, and the relative magnitude of their effect is Ge > Sn > Si > Ga > Al > In > Ni. Other properties are determined for each alloy, such as maximum capacity, charge transfer kinetics, hydrogen diffusion, charge overpotentials, and charge efficiency. Alloy microstructural information is measured by X-ray diffraction, and gas-phase.

Electrochemical properties of LaNi{sub 5{minus}x}Ge{sub x} alloys in Ni-MH batteries

Journal Article Witham, C; Hightower, A; Fultz, B [California Inst. of Tech., Pasadena, CA (United States). Div. of Engineering and Applied Science]; ... - Journal of the Electrochemical Society

Electrochemical studies were performed on LaNi{sub 5{minus}x}Ge{sub x} metal hydride alloys with 0 {le} x {le} 0.5. The authors carried out single-electrode studies to understand the effects of the Ge substituent on the hydrogen absorption characteristics, the electrochemical capacity, and the electrochemical kinetics of hydrogen absorption and desorption. The electrochemical characteristics of the Ge-substituted alloys are compared to those of the Sn-substituted alloys reported earlier. LaNi{sub 5{minus}x}Ge{sub x} alloys show compositional trends similar to LaNi{sub 5{minus}x}Sn{sub x} alloys, but unlike the Sn-substituted alloys, Ge-substituted alloys continue to exhibit facile kinetics for hydrogen absorption/desorption at high solute concentrations.

Sn-substituted LaNi{sub 5} alloys for metal hydride electrodes

Technical Report Wasz, M L; Schwarz, R B [Los Alamos National Lab., NM (United States). Center for Materials Science]; Srinivasan, S; ...

This research examines the efficacy of tin additions to LaNi{sub 5} in improving the hydrogen storage capacity of the material during charging/discharging. Alloys were prepared using high energy ball milling (mechanical alloying), a technique superior to arc casting for alloying elements with a wide disparity in melting points. Characterization by X-ray diffraction and Rietveld analysis shows that tin preferentially occupies the Ni(3g) sites in the LaNi{sub 5} structure, and the unit cell volume increases linearly with tin content to the maximum tin solubility of 7.33 atomic percent (LaNi{sub 4.56}Sn{sub 0.44}). The authors found that powders prepared by mechanical alloying andmore »« less
