Title:

SEPARATOR FOR ELECTRICITY STORAGE DEVICES AND ELECTRICITY STORAGE DEVICE USING SAID SEPARATOR

Document Type and Number:

WIPO Patent Application WO/2016/143378

Kind Code:

A1

Abstract:

Provided are: a separator for electricity storage devices, which has excellent tear strength, compactness and resistive properties; and an electricity storage device which is provided with this separator for electricity storage devices. A separator for electricity storage devices is configured from regenerated cellulose fibers, which are able to be fibrillated by beating, so that the CSF value X (ml) and the relative tear strength Y (mN·m2/g) are within the ranges that satisfy the formulae shown below. In addition, an electricity storage device, in which a separator is interposed between a pair of electrodes, is configured using this separator for electricity storage devices. 0 ≤ X ≤ 150 Formula 1 10 ≤ Y ≤ 70 Formula 2 Y ≥ 0.3X - 5 Formula 3
