Nickel oxide battery cathode prepared by ozonation

Patent ·
OSTI ID:5356131
A method is described for producing a nickel oxide cathode for a high energy density battery consisting of the steps of: impregnating a porous conducting plaque with a soluble nickel salt such that a conducing plate having nickel hydroxide disposed therethrough is formed; next, treating the impregnated conducting plate with a strong alkaline solution such that a nickel salt-strong alkaline mixture is formed thereby; next, ozonating the impregnated conducting plate by passing a stream of gaseous ozone through the plate due to a pressure differential across the plate; and applying a liquid reagent over the impregnated conducting plate while ozonating to facilitate the action of the ozone on the nickel salt-strong alkaline mixture thereby directly converting the mixture to a tetravalent nickel oxyhydroxide with the stable gamma structure having a valence approaching four.
