Abstract:
(EN) Provided is a binder composition for a non-aqueous secondary battery electrode that can form an electrode having excellent bending resistance and can ensure good electrolyte solution injectability in secondary battery production. The binder composition for a non-aqueous secondary battery electrode contains a polymer A. The polymer A includes an aliphatic conjugated diene monomer unit in a proportion of at least 86 mass% and not more than 95 mass%.
(FR) Le but de la présente invention est de fournir une composition de liant pour une électrode de cellule secondaire non aqueuse, avec laquelle une électrode ayant une excellente résistance à la flexion peut être formée, et de bonnes propriétés d'injection d'électrolyte peuvent être assurées pendant la fabrication de cellules secondaires. Cette composition de liant pour une électrode de cellule secondaire non aqueuse contient un polymère A, le polymère A comprenant de 86 à 95 % en masse d'une unité monomère de diène conjugué aliphatique.
