Title:
SEPARATOR FOR SECONDARY BATTERY, AND ELECTROCHEMICAL DEVICE TO WHICH SAME IS APPLIED
Document Type and Number:
WIPO Patent Application WO/2019/135532
Kind Code:
A1
Abstract:
The present invention relates to: a separator for a secondary battery, capable of reducing the use amount of dispersible resin and the use amount of dispersant in order to prevent an increase in resistance, after coating a separator, occurring when a large amount of dispersible resin is used for dispersing an inorganic material; and an electrochemical device to which the same is applied, and can prevent an increase in resistance, occurring after coating a porous separator, by reducing the amount of dispersible resin, improve physical properties and dispersibility by mixing a dispersible resin having a specific weight average molecular weight, and reduce processing costs by preventing the use of an expensive dispersant.
