Title (EN) SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME
(FR) ACCUMULATEUR ET SON PROCÉDÉ DE FABRICATION
(JA) 二次電池およびその製造方法
Abstract:
(EN) The present invention addresses the problem of, when pressing an electrode having an insulating layer applied onto a mixture layer, accelerating the wear of a press roll due to ceramic particles used in the insulating layer. A secondary battery having a mixture layer on a metal foil, an insulating layer provided on the mixture layer, and an electrode pressed after the application of the insulating layer is characterized in that the insulating layer contains ceramic particles and the ceramic particles have a Mohs hardness of less than 9.
(FR) La présente invention aborde le problème, lors de la pression d’une électrode ayant une couche isolante appliquée sur une couche de mélange, d’accélération de l’usure d’un rouleau presseur causée par des particules de céramiques utilisées dans la couche isolante. Selon l’invention, un accumulateur ayant une couche de mélange sur une feuille de métal, une couche isolante disposée sur la couche de mélange, et une électrode pressée après l’application de la couche isolante est caractérisé en ce que la couche isolante contient des particules de céramique et en ce que les particules de céramique ont une dureté de Mohs inférieure à 9.
(JA) 絶縁層が合剤層上に塗布された電極をプレスする場合、絶縁層に使用しているセラミックス粒子によって、プレスロールの磨耗を早める。 金属箔上に合剤層と、当該合剤層上に設けられた絶縁層を有し、前記絶縁層塗布後にプレスした電極を有する二次電池において、前記絶縁層にはセラミックス粒子を含み、前記セラミックス粒子はモース硬度9未満であることを特徴とする二次電池。
