Abstract:
Systems and methods are provided for managing health of electrolytes of redox flow battery system. Components of the system may include a redox rebalancing cells and a gas storage system. The redox rebalancing cell may be operated by plating iron on a plating electrode, treating a negative electrolyte of the redox flow battery system with the plated iron and returning the negative electrolyte to an electrolyte tank. The gas storage system may include a set of expandable gas storage tanks coupled to at least one electrolyte storage tank and an electrolyte rebalancing system of the redox flow battery system.
