Title:
SEPARATOR, METHOD FOR MANUFACTURING SAME, AND BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/080507
Kind Code:
A1
Abstract:
The present invention relates to a separator, which improves a plasticizer extraction rate by adjusting a plasticizer extracting step such that a residue amount of a plasticizer within the separator is reduced. Particularly, various material properties of the separator caused by a plasticizer residue are enhanced by circulating a solvent during an extracting step so as to reduce a concentration gradient in the vicinity of a surface of the separator such that an extraction rate is improved, thereby obtaining performance of a battery and thermal stability.
