Applying a tapered electrode on a porous ceramic support tube by masking a band inside the tube and drawing in electrode material from the outside of the tube by suction
Abstract
An electrode is deposited on a support by providing a porous ceramic support tube (10) having an open end (14) and closed end (16); masking at least one circumferential interior band (18 and 18') inside the tube; evacuating air from the tube by an evacuation system (30), to provide a permeability gradient between the masked part (18 and 18') and unmasked part (20) of the tube; applying a liquid dispersion of solid electrode particles to the outside surface of the support tube, where liquid flows through the wall, forming a uniform coating (42) over the unmasked support part (20) and a tapered coating over the masked part (18 and 18').
