Title:
COMPOSITION FOR ELECTROCHEMICAL ELEMENT FUNCTIONAL LAYER, MULTILAYER BODY FOR ELECTROCHEMICAL ELEMENT, AND ELECTROCHEMICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/189245
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a composition for an electrochemical element functional layer capable of forming a functional layer that excels in wet adhesiveness. The present invention provides a composition for an electrochemical element functional layer including a particulate polymer, wherein the particulate polymer has a volume particle diameter D50 of 1.0-10.0 μm, and the particulate polymer has a particle size distribution α in which the ratio of particles having particle diameters of 1.5 times the volume particle diameter D50 or greater is 0.5-5 vol%, with the particulate polymer as 100 vol%.
