Title (EN) ELECTRODE SHEET PRODUCTION METHOD
(FR) PROCÉDÉ DE PRODUCTION DE FEUILLE D’ÉLECTRODE
(JA) 電極シートの製造方法
Abstract:
(EN) The method comprises: a compression step whereby a band-shaped electrode sheet having an active substance layer, which is an active substance forming portion, is passed between at least a pair of rotating cylindrical compression rolls, and the electrode sheet is pressed to be compressed by the pair of compression rolls; and a cutting step whereby the electrode sheet that underwent the compression step is cut parallel to the length direction of this electrode sheet. With the width of the active substance layer being a first width, the compression step compresses the electrode sheet using compression rolls having a second width that is narrower than the first width.
(FR) L’invention concerne un procédé qui consiste : en une étape de compression selon laquelle une électrode en forme de bande comportant une couche de substance active, laquelle est une partie de formation de substance active, est passée entre au moins une paire de rouleaux de compression cylindriques rotatifs, et la feuille d’électrode est pressée pour être comprimée par la paire de rouleaux de compression ; et une étape de coupe selon laquelle la feuille d’électrode qui a subi l’étape de compression est coupée parallèlement à la direction de la longueur de cette feuille d’électrode. La largeur de la couche de substance active étant une première largeur, l’étape de compression comprime la feuille d’électrode au moyen de compression présentant une deuxième largeur qui est inférieure à la première largeur.
(JA) 回転する少なくとも一対の円柱状の圧縮ロール間に、活物質の形成部である活物質層を備えた帯状の電極シートを通過させ、一対の圧縮ロールにより電極シートを加圧して圧縮する圧縮工程と、圧縮工程を通過した電極シートを該電極シートの長手方向と平行に切断する切断工程とを有する。圧縮工程は、活物質層の幅を第1の幅としたとき、第1の幅以下の第2の幅を有する圧縮ロールで電極シートを圧縮する。
