Process of preparing manganese oxide catalyzed cathodes
Abstract
Abstract METHOD OF RENDERING THE ACTIVE LAYER OF AN ALKALINEELECTROLYTE, OXYGEN-DEPOLARIZED CATHODE CATALYTICALLY ACTIVE WITH A LOW COST MANGANESE OXIDE CATALYST. THE CATHODE IS CAPABLE OF OPERATING AT HIGH CURRENT DENSITIES WITHOUT AN APPRECIABLE BUILDUP OF HYDROGEN PEROXIDE IN THE ELECTROLYTE. THE CATHODE MATERIALS ARE TREATED WITH AN ALCOHOL-SOLVATED MANGANOUS CARBOXYLATE SOLUTION IN THE PRESENCE OF OXYGEN AND A WEAK NON-METAL-CONTAINING ALKALIZER THEREBY FORMING MANGANIC OXIDE HAVING PARTICLE SIZES MOSTLY LESS THAN 0.2 MICRONS IN DIAMTER. THE ACTIVE LAYER MATERIALS AND SOLUTIONS ARE SUBSEQUENTLY HEATED TO DRIVE OFF THE SOLVENT AND ANY NON-MANGANESE OXIDE REACTION PRODUCTS. AN INEXPENSIVELY CATALYZED CATHODE WITH A LOW CATHODIC POLARIZATION AT HIGH CURRENT DENSITIES RESULTS.
