Title:
REDOX FLOW CELL
Document Type and Number:
WIPO Patent Application WO/2020/261792
Kind Code:
A1
Abstract:
The present disclosure provides a redox flow cell for suppressing capacity reduction resulting from crossover of oxidation-reduction species. A redox flow cell (100) according to one embodiment of the present disclosure is provided with: a negative electrode (10); a positive electrode (20); a first liquid (12) including a first nonaqueous solvent, a first oxidation-reduction species (18), and metal ions, and in contact with the negative electrode (10); a second liquid (22) including a second nonaqueous solvent and in contact with the positive electrode (20); and an imperforate metal ion conductive membrane (30) positioned between the first liquid (12) and the second liquid (22). The metal ion conductive membrane (30) is swollen by at least one selected from the group consisting of the first liquid (12) and the second liquid (22), allowing the metal ions to permeate.
