Title:
REDOX FLOW BATTERY
Document Type and Number:
Japanese Patent JP2023099240
Kind Code:
A
Abstract:
To provide a redox flow battery capable of suppressing crossover of redox species.SOLUTION: A disclosed redox flow battery includes: a negative electrode 210; a positive electrode 220; a first liquid 110 containing a first non-aqueous solvent, a first redox species, and metal ions, which is in contact with the negative electrode 210; a second liquid 120 containing a second non-aqueous solvent, second redox species, and metal ions, which is in contact with the positive electrode 220; and a metal ions conductive membrane 400 placed between the first liquid 110 and the second liquid 120. The metal ions conductive membrane 400 contains an organic polymer having multiple hydroxyl groups, and the organic polymer has a group in which at least a portion of the plurality of hydroxyl groups is substituted with a metal sulfonate.SELECTED DRAWING: Figure 1
