Title:
REDOX FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/261793
Kind Code:
A1
Abstract:
The present disclosure provides a redox flow battery in which a capacity decrease caused by the crossover of redox species is suppressed. A redox flow battery (100) according to an aspect of the present disclosure comprises: a negative electrode (10); a positive electrode (20); a first liquid (12) containing a first non-aqueous solvent, a first redox species (18), and metal ions, and in contact with the negative electrode (10); a second liquid (22) containing a second non-aqueous solvent and in contact with the positive electrode (20); and a metal-ion-conductive membrane (30) disposed between the first liquid (12) and the second liquid (22). The metal-ion-conductive membrane (30) has a plurality of inorganic particles (31) and a binder (32) which contains an organic polymer and binds the plurality of inorganic particles (31) to each other.
