Title:
BATTERY ELECTRODE, METHOD FOR MANUFACTURING SAME, AND DEVICE FOR MANUFACTURING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2018/179205
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a battery electrode in which a coating layer can be formed in a boundary section with a sufficient margin; and a method for manufacturing same. To this end, this method for manufacturing an electrode is a method in which a second layer is coated on at least a boundary section between a first layer and a base material having a portion on which the first layer is formed. The method is characterized in that, in a region directly in front of the boundary section on the base material, with respect to the gap between a coating device and the base material, the second layer is coated with a second gap that is smaller than a first gap corresponding to a wet thickness that is determined by the amount of discharged coating fluid and by the moving speed of the base material, and coating is performed on the first layer with a third gap corresponding to the sum of the thickness of the first layer and the first gap.
