Title:
AQUEOUS RESIN COMPOSITION FOR LITHIUM ION SECONDARY BATTERY SEPARATORS, SLURRY FOR FUNCTIONAL LAYERS OF LITHIUM ION SECONDARY BATTERY SEPARATORS, AND SEPARATOR FOR LITHIUM ION SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/004420
Kind Code:
A1
Abstract:
The present invention provides an aqueous resin composition for lithium ion secondary battery separators, the aqueous resin composition containing organic particles (A) and an aqueous medium (B), while being characterized in that the volume average particle diameter of the organic particles (A) is 6 µm to 20 µm. Since this aqueous resin composition for lithium ion secondary battery separators enables the achievement of a separator which has excellent adhesion to an electrode and excellent thermal shrinkage resistance by single coating with excellent workability, this aqueous resin composition is suitably used for lithium ion secondary battery separators.
