Abstract:
(EN) The purpose of the present invention is to provide: a negative electrode active material paint which can provide a secondary battery having low cost, high capacity and excellent electric characteristics; a negative electrode; and a secondary battery. According to the present invention, this negative electrode active material paint, which contains a negative electrode active material, a conductive agent, an aqueous binder, water and a solvent, is characterized in that the boiling point of the solvent is 200-300°C, the water solubility is 20 g/L or more, and the content of the solvent is 0.05-5 mass% with respect to 100% of the negative electrode active material paint.
(FR) L’objectif de la présente invention est de fournir : une peinture de matériau actif d’électrode négative qui peut produire une batterie rechargeable ayant un faible coût, une capacité élevée et d’excellentes caractéristiques électriques ; une électrode négative ; et une batterie rechargeable. Selon la présente invention, cette peinture de matériau actif d’électrode négative, qui contient un matériau actif d’électrode négative, un agent conducteur, un liant aqueux, de l’eau et un solvant, est caractérisée en ce que le point d’ébullition du solvant est de 200 à 300 °C, la solubilité dans l’eau est de 20 g/l ou plus, et la teneur en solvant est de 0,05 à 5 % en masse par rapport à 100 % de la peinture de matériau actif d’électrode négative.
(JA) 本発明の目的は、低コストで高容量かつ電気特性に優れた二次電池を供することが出来る負極活物質塗料、負極、および二次電池を提供すること。 本発明は、負極活物質、導電剤、水系バインダー、水、および溶媒を含有する負極活物質塗料であって、上記溶媒の沸点が200℃以上300℃以下、かつ水溶解度が20g/L以上であり、上記溶媒の含有量が、負極活物質塗料100%に対し、0.05質量%以上5質量%以下であることを特徴とする負極活物質塗料である。
