Abstract
Official abstract text for this publication.
In addition, the present invention is characterized by including a preparation step for preparing an electrode foil, an attachment step for attaching an adhesive member onto a portion of the electrode foil, a coated part formation step for coating an active material onto the electrode foil, and an uncoated part formation step for forming an uncoated part on the electrode foil by removing the adhesive member along with the active material coated onto the adhesive member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing an electrode, the method characterized by comprising: a step S 1 of providing an electrode foil; an attachment step S 2 for attaching an adhesive member onto a portion of the electrode foil; a coated part formation step S 3 for coating an active material onto the electrode foil; and an uncoated part formation step S 4 for forming an uncoated part on the electrode foil by removing the adhesive member along with the active material coated onto the adhesive member, wherein the method is characterized in that, in the attachment step S 2 , the adhesive member is attached onto the electrode foil such that the adhesive member is spaced apart a predetermined distance from an outermost line of the area to be coated with the active material in the coated part formation step S 3 , and wherein the predetermined distance is 1.9-2.1 cm. 2. The method of claim 1 , wherein the method is characterized in that, in the attachment step S 2 , the adhesive member is attached onto the electrode foil such that the adhesive member is spaced apart a predetermined distance from an end part of the electrode foil. 3. The method of claim 1 , wherein the method is characterized in that, in the attachment step S 2 , an adhesive film or an adhesive tape is attached as the adhesive member onto the electrode foil. 4. The method of claim 1 , wherein the method is characterized in that, in the coated part formation step S 3 , the active material is coated onto the electrode foil such that an end part of the electrode foil is not coated with the active material.
