Abstract:
(EN) Provided is a binder for an electrode which has sufficient binding force and can reduce resistance of a nonaqueous electrolyte secondary battery. The binder for a nonaqueous electrolyte secondary battery electrode includes: a copolymer of a vinyl alcohol and an ethylenically unsaturated carboxylic acid alkali metal neutralization product; and a polyvinyl alcohol.
(FR) L'invention fournit un liant pour électrode qui présente une capacité de liaison suffisante, et qui permet d'abaisser la résistance d'une batterie secondaire à électrolyte non aqueux. Plus précisément, l'invention concerne un liant pour électrode de batterie secondaire à électrolyte non aqueux qui contient un copolymère d'alcool vinylique et de produit neutralisé de métal alcalin d'acide carboxylique éthyléniquement insaturé, et un alcool polyvinylique.
(JA) 十分な結着力を有し、非水電解質二次電池を低抵抗化できる電極用バインダーを提供する。 非水電解質二次電池電極用バインダーは、ビニルアルコールとエチレン性不飽和カルボン酸アルカリ金属中和物との共重合体、及びポリビニルアルコールを含む。
