Title (EN) BINDER COMPOSITION FOR SOLID ELECTROLYTE BATTERIES
(FR) COMPOSITION DE LIANT DESTINÉE À DES BATTERIES À ÉLECTROLYTE SOLIDE
(JA) 固体電解質電池用バインダー組成物
Abstract:
(EN) The purpose of the present invention is to provide a binder composition for solid electrolyte batteries, which exhibits excellent processability during the production of a solid electrolyte battery, and which enables the achievement of a solid electrolyte battery that has excellent battery performance. A binder composition for solid electrolyte batteries according to the present invention contains an organic solvent and a particulate polymer that has a core-shell structure. The mass ratio of the content of the polymer constituting the core part of the particulate polymer to the content of the polymer constituting the shell part of the particulate polymer, namely (polymer constituting core part)/(polymer constituting shell part) is from 1/0.3 to 1/5.
(FR) La présente invention vise à fournir une composition de liant destinée à des batteries à électrolyte solide, qui présente une excellente aptitude au traitement pendant la production d'une batterie à électrolyte solide, et qui permet d'obtenir une batterie à électrolyte solide dotée d'excellentes performances de batterie. Une composition de liant destinée à des batteries à électrolyte solide selon l'invention contient un solvant organique et un polymère particulaire qui présente une structure cœur-écorce. Le rapport massique de la teneur du polymère constituant la partie noyau du polymère particulaire par rapport à la teneur du polymère constituant la partie enveloppe du polymère particulaire, c'est à dire (polymère constituant la partie noyau) / (polymère constituant la partie enveloppe) est compris entre 1/0,3 et 1/5.
(JA) 本発明は、固体電解質電池の製造の際のプロセス性に優れ、電池性能に優れた固体電解質電池を得ることができる固体電解質電池用バインダー組成物を提供することを目的とする。本発明の固体電解質電池用バインダー組成物は、コア-シェル構造を有する粒子状ポリマーと、有機溶媒とを含み、前記粒子状ポリマーのコア部を構成する重合体の含有量と、シェル部を構成する重合体の含有量との質量比が、「コア部を構成する重合体」/「シェル部を構成する重合体」の比率にて、1/0.3~1/5である。
