Abstract:
1. A method for applying an electrode mixture paste, comprising: an application step of applying an electrode mixture paste by a coating unit on both sides of a strip of core material as the core material runs along a lengthwise direction thereof; and a coating thickness/width adjusting step of adjusting a coating thickness of the electrode mixture paste as the core material coated with the electrode mixture paste passes through a gap between a pair of scraper tools, and forming a paste-coated portion of a predetermined width by scraping off the electrode mixture paste using tips provided to the scraper tools, the electrode mixture paste scraped off with the tips being returned through recesses formed on an upstream side of the tips in a running direction of the core material, wherein the recesses open toward the coating unit, and return at least part of the electrode mixture paste toward the coating unit, and side edges of the recess protrude from side edges of the tip by p, p being in a range of from −0.1 w to 0.5 w, where w is a width of the tip.
