Abstract:
(EN) The main purpose of the present invention is to provide a binder for electrodes, which has excellent flexibility and binding properties, and which enables an electricity storage device such as a lithium ion secondary battery and an electrochemical capacitor to have a lower internal resistance at an SOC of 50%. Another purpose of the present invention is to provide: an electrode which is obtained using this electrode binder; and an electricity storage device which is provided with this electrode. A binder for electrodes, which contains a polymer (A) that has a constituent unit derived from a (meth)acrylic acid ester and a constituent unit derived from a polyfunctional (meth)acrylate and a non-crosslinked polymer (B) that has a constituent unit derived from an alkoxyalkyl (meth)acrylate and a constituent unit derived from a (meth)acrylic acid; an electrode which is obtained using this binder for electrodes; and an electricity storage device which is provided with this electrode.
(FR) Le but principal de la présente invention est de fournir un liant pour électrodes, qui présente d'excellentes propriétés de flexibilité et de liaison, et qui permet à un dispositif de stockage d'électricité tel qu'une batterie secondaire au lithium-ion et un condensateur électrochimique d'avoir une résistance interne inférieure à un SOC de 50 %. L'invention a pour autre objectif de fournir : une électrode qui est obtenue à l'aide du liant pour électrodes; et un dispositif de stockage d'électricité qui est muni de ladite électrode. Un liant pour électrodes, qui contient un polymère (A) qui a une unité constitutive dérivée d'un ester d'acide (méth)acrylique et d'une unité constitutive dérivée d'un (méth)acrylate polyfonctionnel et d'un polymère non réticulé (B) qui a une unité constitutive dérivée d'un (méth)acrylate d'alcoxyalkyle et d'une unité constitutive dérivée d'un acide (méth)acrylique; une électrode qui est obtenue à l'aide de ce liant pour des électrodes; et un dispositif de stockage d'électricité qui comprend cette électrode.
(JA) 優れた可撓性及び結着性を備えており、リチウムイオン二次電池や電気化学キャパシタといった蓄電デバイスにおいて、SOC50%における内部抵抗の低抵抗化を実現する電極用バインダーを提供することを主な目的とする。更に、本発明は、該電極バインダーを用いてなる電極、及び該電極を備える蓄電デバイスも提供することを目的とする。 (メタ)アクリル酸エステルに由来する構成単位と多官能(メタ)アクリレートに由来する構成単位を有する重合体Aと、(メタ)アクリル酸アルコキシアルキルに由来する構成単位と(メタ)アクリル酸に由来する構成単位を有する非架橋重合体Bとを含む電極用バインダー、該電極用バインダーを用いてなる電極、及び該電極を備える蓄電デバイスである。
