REDOX FLOW CELL COMPRISING HIGH MOLECULAR WEIGHT COMPOUNDS AS REDOX PAIR AND SEMIPERMEABLE MEMBRANE FOR STORAGE OF ELECTRICAL ENERGY

摘要

The problem addressed was that of providing, through the use of novel materials and membranes, at minimum cost and inconvenience, an inexpensive and long-lived redox flow cell having redox-active compounds which, even in the possible event of cell failure, result in a low level of environmental pollution. The redox-active components envisaged in accordance with the invention are high molecular weight compounds such as redox-active polymers or oligomers, and the membrane envisaged is a size exclusion membrane (3) for separation of the high molecular weight redox-active components.
