Abstract
(EN) Provided is a binder composition that is for a secondary battery porous membrane, that comprises polycarboxylic acid and water, and wherein: the polycarboxylic acid contains 20-50 mass% of a carboxylic acid group-containing monomer unit; the polycarboxylic acid is water-insoluble at a pH of 6.5 or less and water-soluble at a pH of 8 or more; and the pH of the binder composition for a secondary battery porous membrane is 6.5 or less. Also provided are a slurry for a secondary porous battery membrane, a porous membrane for a secondary battery, and a secondary battery that use the binder composition.
(FR) La présente invention concerne une composition de liant pour une membrane poreuse de batterie secondaire, ladite composition de liant comprenant de l'acide polycarboxylique et de l'eau. Dans ladite invention : l'acide polycarboxylique contient de 20 à 50 % en masse d'une unité monomère qui contient un groupe acide carboxylique ; l'acide polycarboxylique est insoluble dans l'eau à un pH de 6,5 ou moins et de soluble dans l'eau à un pH de 8 ou plus ; et le pH de la composition de liant pour une membrane poreuse de batterie secondaire est de 6,5 ou moins. La présente invention concerne également une bouillie pour une membrane poreuse de batterie secondaire, une membrane poreuse pour une batterie secondaire, et une batterie secondaire qui utilisent la composition de liant.
