Abstract
A nickel oxide electrode is made by impregnating a porous nickel substrate with a dispersion of a nickel compound, converting the compound in situ to nickel hydroxide, and removing reaction products. In order to overcome corrosion problems, facilitate removal of by-products and improve electrode performance, the dispersion is provided in a non-aqueous medium (e.g. as a methanolic solution of NiCl.sub.2.6H.sub.2 O) such that the in situ conversion gives rise to the nickel hydroxide in the form of a gel and to easily removable (e.g. volatile) reaction products. Such a conversion may be carried out by contacting the methanolic solution with an epoxy compound such as propylene oxide.
