Title:
SEPARATOR AND ELECTROCHEMICAL DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/093798
Kind Code:
A1
Abstract:
Provided are a separator including a porous polymer substrate made of a polymer, in which a change rate of a phase angle at 0.1 Hz according to a temperature rise follows the following formula, and an electrochemical device comprising the same. [Formula 1] change rate of phase angle at 0.1Hz = [(phase angle190 – phase angle280)/(phase angle190)] X 100 ≥ 0% wherein phase angle190 is a phase angle of the porous polymer substrate at 0.1 Hz at 190°C and phase angle280 is a phase angle of the porous polymer substrate at 0.1Hz at 280°C.
