Title:
PREPARATION METHOD FOR SEPARATOR FOR ELECTROCHEMICAL DEVICE AND SEPARATOR FOR ELECTROCHEMICAL DEVICE PREPARED BY SAME PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/146056
Kind Code:
A1
Abstract:
Two types of solvents are used when coating an adhesive layer, and a beta crystalline phase of a second binder resin is induced due to a polarity ratio, and as a result, uniform porous structures are formed, thus improving movement paths of lithium ions, such that even when the adhesive layer is formed, resistance of a separator does not increase.
