Title:
リチウムイオン電池用電極の製造方法
Document Type and Number:
Japanese Patent JP6402200
Kind Code:
B2
Abstract:
Provided is a method for manufacturing an electrode for a lithium ion battery, in which 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 the powder layer is compacted on the substrate by means of a pair of press rolls while conveying the substrate vertically downward to thereby form an electrode sheet, the method comprising: a supplying step for supplying the powder onto the substrate; a powder layer forming step for 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 ¸ is 0°-60°, the squeegee angle ¸ being the 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; and a compacting step for compacting the powder layer on the substrate using the pair of press rolls.
