Title (EN) BINDER FOR ELECTROCHEMICAL ELEMENTS
(FR) LIANT POUR ÉLÉMENTS ÉLECTROCHIMIQUES
(JA) 電気化学素子用バインダー
Abstract:
(EN) A binder for electrochemical elements, which contains a polyamide that has one or more functional groups selected from among a carboxyl group and salts of a carboxyl group, and which is configured such that the weight average molecular weight of the polyamide in terms of PEG as determined by gel permeation chromatography is from 400,000 to 9,000,000 (inclusive).
(FR) L'invention concerne un liant pour éléments électrochimiques, qui contient un polyamide qui a un ou plusieurs groupes fonctionnels choisis parmi un groupe carboxyle et des sels d'un groupe carboxyle, et qui est configuré de telle sorte que le poids moléculaire moyen en poids du polyamide en termes de PEG tel que déterminé par chromatographie par perméation de gel est de 400000 à 9000000 (inclus).
(JA) カルボキシル基及びカルボキシル基の塩から選択される1以上の官能基を有するポリアミドを含む電気化学素子用バインダーであって、前記ポリアミドの重量平均分子量が、ゲルパーミッションクロマトグラフィーによるPEG換算で400,000以上9,000,000以下である電気化学素子用バインダー。
