Abstract
Abstract STABLE, HIGH SURFACE AREA MANGANESE FIBERS HAVING A CERTRAL SPINE PORTION WITH SOME POLY-DIRECTIONAL SIDE GROWTHS. THE MANGANESE FIBERS ARE PREPARED BY THE ELECTROLYSIS OF A SOLUBLE MANGANESE SALT-CONTAINING ELECTROLYTE SOLUTION UNDER CONDITIONS OF EXTREMELY HIGH CATHODE CURRENT DENSITY. GALVANIC CELL ELECTRODES ARE FABRICATED USING THE MANGANESE FIBERS BY COMPRESSION MOLDING TECHNIQUES.
