METHOD AND SYSTEM FOR REDOX FLOW BATTERY PERFORMANCE RECOVERY

A method for a redox flow battery may include, interrupting cycling of the redox flow battery, including charging the redox flow battery to a threshold charge condition, draining positive and negative electrolyte from the redox flow battery, circulating a wash solution through the redox flow battery, and returning the positive and negative electrolyte to the redox flow battery, and resuming cycling of the redox flow battery. In this way, contamination of the redox flow battery system can be reduced, thereby prolonging the life and increasing performance of the redox flow battery system.
