    • Sintered-nickel porous plaques are made by dispersing a slurry of fine nickel particles on a nickel-coated steel mesh and sintering at 1000 °C under vacuum in order to weld the nickel particles to each other and to the mesh. The resultant plaque will have high porosity and a high surface area.

    • Nickel oxide mixed with a binder is extruded into hollow fibres. The fibres are spread into a slurry and sintered under a reducing atmosphere whereby the nickel oxide fibres become reduced to metallic nickel fibres. The fibrous plaques have 12% higher porosity but only a twentieth the surface area of a sintered-nickel porous plaque.

    • In a pasted electrode, the active material is mixed with a conductive material such as graphite, nickel or cobalt metal powder and a binder. The resultant pulp is hotpressed onto a nickel mesh under high pressure. A dip-loaded electrode is made by dipping the sintered plaque alternately in solutions of nickel nitrate and KOH to precipitate chemically the active material into the pores. The dip-loaded electrodes are formed by cathodically polarizing them in 6 M KOH solution. Hydrogen evolution that takes place during this process is expected to introduce beneficial morphological changes in the dip-loaded active material. Poured electrodes are made by pouring a slurry of the active material made in a medium such as acetone on a nickel foam and allowing the medium to dry.
