Summary: | This binder composition for electricity storage device electrodes contains a polymer (A) and a liquid medium (B), and is characterized in that: a repeating unit (A4) derived from an unsaturated carboxylic acid is contained in an amount of 5-40 parts by mass when the total amount of repeating units contained in the polymer (A) is taken as 100 parts by mass; the polymer (A) is in the form of polymer particles; and the surface acid amount of the polymer particles is more than 1 mmol/g but 6 mmol/g or less.
La présente composition de liant pour électrodes de dispositif accumulateur d'électricité contient un polymère (A) et un milieu liquide (B) et est caractérisée en ce que : une unité répétitive (A4) dérivée d'un acide carboxylique insaturé est contenue dans une quantité de 5 à 40 parties en masse quand la quantité totale d'unités répétitives contenues dans le polymère (A) est définie à 100 parties en masse ; le polymère (A) est présent sous forme de particules de polymère ; et la teneur en acide de surface des particules de polymère est comprise entre 1 mmol/g et 6 mmol/g inclus. |
