Provided is a binder composition for a storage device that makes it possible to form a layer that adheres well to a collector or a separator and to produce a storage device having excellent charge/discharge characteristics. A binder composition for a storage device according to the present invention is characterized in containing: a water-soluble polymer (A) that contains repeating units derived from (meth)acrylamide and has a weight-average molecular weight (Mw) of 3 × 105-6 × 106; and a liquid medium (C). L'invention concerne une composition de liant destinée à un dispositif de stockage, qui permet, non seulement de réaliser une couche qui adhère bien à un collecteur ou à un séparateur, mais aussi de produire un dispositif de stockage présentant d'excellentes caractéristiques de charge et décharge. La composition de liant pour dispositif de stockage selon l'invention est caractérisée en ce qu'elle contient, d'une part un polymère hydrosoluble (A) qui contient des unités répétitives dérivées de méthacrylamide et présente un poids moléculaire moyen en poids (Mw) de 3 × 105-6 × 106, et d'autre part un milieu liquide (C).
