Abstract
The present invention is directed to a novel method of fabricating and composition for chalcogenide cathode-active electrodes. The method comprises the steps of: PA0 (a) combining the cathode-active material in particulate form with about 0.1 to about 10 percent by weight of a neutralized sulfonated ionomer, based on the total weight of the cathode-active material and the ionomer, and about 10 to about 90 percent by weight of solvent, based on the total weight of the cathode-active material, ionomer and solvent, wherein said solvent is a cosolvent system which includes one or more solvents selected from the group consisting of normal and aromatic hydrocarbons and one or more solvents selected from the group consisting of alcohols, amines, amides, nitriles, nitro-compounds, lactones and acetols; PA0 (b) forming the desired electrode configuration with the resulting mixture; and PA0 (c) drying the formed electrode so as to volatilize the solvent. The composition consists essentially of PA0 (a) a chalcogenide material in a particulate form consisting of one or more compounds selected from a group consisting of the sulfides, selenides and tellurides of titanium, zirconium, hafnium, nio…
