Title:
NON-WOVEN FABRIC AND SEPARATOR FOR ELECTROCHEMICAL ELEMENTS
Document Type and Number:
WIPO Patent Application WO/2020/100654
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a non-woven fabric having such mechanical strength as to be resistant to being cut or broken by an external force, and a separator for electrochemical elements in which the non-woven fabric is used. The zero-span tensile strength of this non-woven fabric in the longitudinal and lateral directions per unit weight per area is 6.5 N/50 mm or greater in total. Thus, the strength of constituent fibers of the non-woven fabric with respect to external forces is high, and the non-woven fabric has such mechanical strength as to be resistant to being cut or broken by an external force. This separator for electrochemical elements is configured from the non-woven fabric.
