Title:
ELECTROLYTE MEMBRANE, ELECTROLYSIS DEVICE AND REDOX FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/085630
Kind Code:
A1
Abstract:
The present invention provides: an electrolyte membrane which is not susceptible to the generation of a pinhole if used in a cell that has an anode and a cathode, while being applied with a voltage for a long period of time; and an electrolysis device and a redox flow battery, each of which comprises this electrolyte membrane. An electrolyte membrane which comprises a woven fabric and a fluorine-containing polymer that has an ion exchange group, wherein: the woven fabric is composed of a yarn A that extends in one direction and a yarn B that extends in a direction which is generally perpendicular to the yarn A; the aspect ratio YACA2/YACA1 is more than 1, while being higher than the aspect ratio YAA2/YAA1; and the aspect ratio YACB2/YACB1 is more than 1, while being higher than the aspect ratio YAB2/YAB1. (Meanwhile, YACA2, YACA1, YAA2, YAA1, YACB2, YACB1, YAB2 and YAB1 are as defined in the description.)
