摘要： An improved apparatus and method of producing metal foam is provided which involves optimizing the natural convection of electrolyte through a foam being electroplated by inclining the foam during plating. A diagonal flow of electrolyte though the foam enhances electrolyte turnover within the foam while increasing electroplating efficiency. Further increases in plating efficiency are provided by shifting current density from higher plating zones to lower plating zones.

摘要： This process produces nickel hydroxide from elemental nickel. Introducing elemental nickel into at least a 4N aqueous ammonia solution forms a mixture. Activating the nickel powder of this mixture allows the nickel to react with oxygen in the solution. This results in the dissolving of the nickel, producing a loaded solution containing nickel and hydroxyl ions. The redox potential of the solution remains negative during the dissolution of nickel. Distilling the loaded solution to vaporize the aqueous ammonia solution results in the precipitating of nickel hydroxide.

摘要： A porous nickel electrode substrate having a central high conductivity core sandwiched between two layers of porous conductive material such as nickel foam or nickel felt. The porous conductive material is plated with nickel and then sintered. By selectively controlling the plating of nickel on the porous material, variable conductivities may be designed into the substrate.

摘要： A process for decreasing the crystallinity of nickel hydroxide by generating and supplying large numbers of heteronuclei into the nickel hydroxide producing reaction system. Nickel sulfate and sodium hydroxide are initially forcefully and intimately combined to form a supersaturated solution of heteronuclei. These heteronuclei are introduced into a nickel powder containing slurry wherein nickel hydroxide having a crystallinity FWHM value of greater than about 0.5° is generated.

摘要： The process precipitates additives onto nickel hydroxide seeds in an ammonia solution. Then introducing at least one metallic additive into the aqueous solution creates a slurry having a reducing potential. The additive is selected from the group consisting of aluminum, cadmium, cobalt, indium, iron, manganese and zinc. Introducing oxygen into the additive-containing slurry at a controlled rate maintains the reducing potential of the solution. At least one of the additives dissolves into the aqueous solution in excess of the slurry's solution solubility to precipitate the additive in the form of a hydroxide on the nickel hydroxide seeds.
