  • Electrochemical cell
    Patent number: 4752546
    Abstract: The invention relates to an electrochemical cell having a negative electrode of a stable hydride-forming material, in which a high power density at a low temperature and a rapid activation (as a function of the number of charge and discharge cycles) are obtained by adding to the electrochemically active material one or more metals selected from the group formed by Ni, Pd, Pt, Ir and Rh.The activating metal may be added to the bulk of the hydride-forming material or may be provided by substituting it for less noble metals at the surface of the powdered material.
    Type: Grant
    Filed: August 20, 1987
    Date of Patent: June 21, 1988
    Inventors: Jacobus J. F. G. Heuts, Johannes J. G. S. A. Willems
  • Electrochemical cell
    Patent number: 4702978
    Abstract: The invention relates to an electrochemical cell having a negative electrode of a stable hydride-forming material, in which a high power density at a low temperature is obtained by adding from 5 to 45% by weight of LaNi.sub.5 or a comparable high-capacity material having a higher plateau pressure than that of the stable hydride-forming material.
    Type: Grant
    Filed: November 18, 1986
    Date of Patent: October 27, 1987
    Assignee: U.S. Philips Corporation
    Inventors: Jacobus J. F. G. Heuts, Gerrit Frens
