ELECTRODE MIXTURE PASTE COATING METHOD AND COATER

摘要

A method for applying electrode mixture paste in which a strip of core material (1) made of porous metal sheet is driven to run along its lengthwise direction, is turned around part of the outer surface of a roll (8) immersed in the electrode mixture paste (6), and is driven forward by rotating the roll (8) so that the paste (6) is applied on both sides of the core material (1), after which the coating thickness of the paste (6) is adjusted and the coated paste (6) is dried. The roll (8) is formed with grooves (16) in the outer surface extending along the rotating direction so that the electrode mixture paste (6) that has entered between the outer surface of the roll (8) and the core material (1) is smoothly released, whereby the core material (1) is prevented from meandering and deterioration of coating precision is avoided. The invention thus realizes a method for applying electrode mixture paste that avoids deterioration of coating precision even when the paste has a high viscosity.
