Title (EN) BINDER FOR BATTERY ELECTRODE, ELECTRODE, AND BATTERY
(FR) LIANT POUR ÉLECTRODE DE BATTERIE, ÉLECTRODE, ET BATTERIE
(JA) 電池電極用バインダー、電極、及び電池
Abstract:
(EN) Provided is a binder for a battery electrode, the binder having superior binding properties and being capable of effectively decreasing the internal resistance of a battery while still being usable as an aqueous binder with low environmental burden. A binder for a battery electrode according to the present invention has a core shell structure of a core section (A) containing a copolymer the principal constituent of which is methyl methacrylate and a shell section (B) having a (meth)acrylate-based copolymer containing (meth)acrylate as a polymerization component, wherein the swelling ratios with respect to a mixed solvent in which ethylene carbonate and diethyl carbonate are mixed at a volume ratio of 3:7 are 10% or less for the resin constituting the core section (A) and 30% or more for the resin constituting the shell section (B).
(FR) L'invention concerne un liant pour une électrode de batterie, le liant ayant d'excellentes propriétés de liaison et étant apte à réduire efficacement la résistance interne d'une batterie tout en étant utilisable comme liant aqueux à faible impact environnemental. Un liant pour une électrode de batterie selon la présente invention présente une structure type cœur-écorce constituée d'une partie cœur (A) contenant un copolymère, dont le constituant principal est le méthacrylate de méthyle et d'une partie écorce (B) comportant un copolymère à base de (méth)acrylate contenant du (méth)acrylate comme constituant de polymérisation, les taux de gonflement par rapport à un solvant mélangé dans lequel du carbonate d'éthylène et du carbonate de diéthyle sont mélangés selon un rapport volumique de 3:7 étant inférieurs ou égaux à 10 % pour la résine constituant la partie cœur (A) et 30 % ou plus pour la résine constituant la partie écorce (B).
(JA) 環境負荷の小さな水系のバインダーとして使用することができながら、結着性に優れ、かつ、電池の内部抵抗を効果的に低下させることができる電池電極用バインダーを提供する。 メタクリル酸メチルを主成分とする共重合体を含有するコア部(A)と、(メタ)アクリレートを重合成分として含有する(メタ)アクリレート系共重合体を有するシェル部(B)とのコアシェル構造を有しており、 エチレンカーボネートとジエチルカーボネートが3:7の体積比で混合された混合溶媒に対する膨潤率が、前記コア部(A)を構成する樹脂は10%以下であり、かつ、前記シェル部(B)を構成する樹脂は30%以上である、電池電極用バインダー。
