-37/114 ABSTRACT OF THE DISCLOSURE The present invention is an improvement in the man- ufacture of sintered nickel plaque electrode material by a method which comprises blending together, either in the dry or wet state, nickel metal powder and one or more binders, then coating or doctoring the resulting blend on a current collector, such as an iron or nickel grid, and sintering the composite to reduce the blend to a porous nickel plaque adhering strongly to the current collector. The improvement comprises adding a selected pore-forming material to the blend before coating ox doctoring the blend onto the current collector. The pore former is a material that is selected from the group consisting of nickel oxide, nickel carbonate, nickel hydroxide, nickel oxalate and mixtures thereof, with the first three named materials being preferred. The most preferred species is nickel oxide. The pore former can be added to the blend in any suitable concentra- tion, for example 1 percent or more, with concentrations as high as 30 or 40 weight percent being effective to increase the por- osity of the finished plaque material substantially over that of nickel plaque formed without using the pore former. The pore former is converted during the sintering operation to pure nickel but in the process results in the formation. of the desired in- creased concentration of voids in the plaque. The pore formers utilized in accordance with the improvements of the present method are inexpensive, readily available and highly effective.
