Document Type and Number:
WIPO Patent Application WO/2023/053989
Kind Code:
A1
Abstract:
The power storage device separator binder aqueous solution comprises a water-soluble polymer (A) and a water-soluble polymer (B). The water-soluble polymer (A) contains 65-99 mol% of a (meth)acrylamide group-containing compound unit and 1-30 mol% of a hydroxyl group-containing monomer unit. The weight-average molecular weight of the water-soluble polymer (A) is 100,000-1,000,000. The water-soluble polymer (B) contains 50-99.99 mol% of an unsaturated carboxylic acid and/or salt thereof unit and 0.01-5 mol% of a multifunctional monomer unit. The weight-average molecular weight of the water-soluble polymer (B) is 10,000-1,000,000. The pH of the power storage device separator binder aqueous solution is 3-9.
