  • Patent number: 5549991
    Abstract: A battery is provided comprising an aluminum anode, an aqueous solution of permanganate as the cathodic species and a second electrode capable of reducing permanganate. Such a battery system is characterized by its high energy density and low polarization losses when operating at high temperatures in a strong caustic electrolyte, i.e., high concentration of hydroxyl ions. A variety of anode and electrocatalyst materials are suitable for the efficient oxidation-reduction process and are elucidated.
    Type: Grant
    Filed: November 30, 1993
    Date of Patent: August 27, 1996
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Stuart L. Licht, Catherine L. Marsh
  • Patent number: 5472807
    Abstract: A battery capable of producing high current densities with a high charge acity is described which includes an aluminum anode, a ferricyanide electrolyte and a second electrode capable of reducing ferricyanide electrolyte which is either dissolved in an alkaline solution or alkaline seawater solution. The performance of the battery is enhanced by high temperature and high electrolyte flow rates.

  • Patent number: 5445905
    Abstract: A novel dual flow battery configuration is provided comprising an aqueous drogen peroxide catholyte, an aqueous anolyte, a porous solid electrocatalyst capable of reducing said hydrogen peroxide and separating said anolyte, and an aluminum anode positioned within said anolyte. Separation of catholyte and anolyte chambers prevents hydrogen peroxide poisoning of the aluminum anode.
