Abstract
A method for manufacturing an electrode for a lithium ion battery is provided. A powder layer is formed by using a squeegee roll to squeegee powder including an electrode active material and supplied onto a substrate, and then compacted on the substrate by means of a pair of press rolls while conveying the substrate vertically downward to form an electrode sheet. The method includes: supplying the powder onto the substrate; leveling the powder supplied onto the substrate to form the powder layer using the squeegee roll which is disposed in a position so that a squeegee angle formed by a vertical line passing through the rotating axis of one of the press rolls and a line passing through said rotating axis and the rotating axis of the squeegee roll is 0° to 60°; and compacting the powder layer on the substrate using the pair of press rolls.
