Document Type and Number:
WIPO Patent Application WO/2024/024949
Kind Code:
A1
Abstract:
A binder composition for a secondary battery, said binder composition including water-soluble macromolecules (X), a water-soluble compound (Y), and polymer particles, wherein the water-soluble macromolecules (X) are a polymer that includes a constituent component having a prescribed structure, and the binder composition satisfies properties in which the tensile elastic modulus of the binder composition is 1500-9800 MPa, and as measured according to specific parameters, the difference in the storage elastic modulus at shear strains of 0.01% and 10% is 100-1000 Pa. Additionally, an electrode sheet, a secondary battery, a manufacturing method for said electrode sheet, and a manufacturing method for said secondary battery.
