Zusammenfassung: | To provide a binder aqueous solution for a lithium ion battery, a slurry for a lithium ion battery negative electrode, a negative electrode for a lithium ion battery and a lithium ion battery.SOLUTION: A binder aqueous solution for a lithium ion battery is provided according to a disclosure hereof, which comprises a water-soluble poly(meth)acrylamide (A) consisting of a polymer of a group of monomers including 30-95 mol% of a (meth)acrylamide group-containing compound (a) and 5-40 mol% of an alkoxy alkyl (meth)acrylate (b) represented by the general formula (1) below to 100 mol% of the group of monomers. CH2=C(R1)-CO-O-R2-O-R3 (1) (In the formula, R1 is a hydrogen atom or a methyl group, R2 is an alkylene group with 1-4 carbon atoms, and R3 is an alkyl group with 1-4 carbon atoms, and a total number of carbon atoms of the groups of R1, R2 and R3 is 5 or less.)SELECTED DRAWING: None
【課題】リチウムイオン電池用バインダー水溶液、リチウムイオン電池負極用スラリー、リチウムイオン電池用負極及びリチウムイオン電池を提供すること。【解決手段】本開示は、単量体群100モル%に対して、(メタ)アクリルアミド基含有化合物(a)を30〜95モル%、及び下記一般式(1)で示されるアルコキシアルキル(メタ)アクリレート(b)を5〜40モル%含む単量体群の重合物である水溶性ポリ(メタ)アクリルアミド(A)を含む、リチウムイオン電池用バインダー水溶液。CH2=C(R1)−CO−O−R2−O−R3(1)(式中、R1は水素原子、又はメチル基であり、R2は炭素数1〜4のアルキレン基であり、R3は炭素数1〜4のアルキル基である。また、R1、R2、及びR3の基の合計の炭素数が5以下である。)を提供する。【選択図】なし |
