Abstract
During operation of flow battery systems, the volume of one or more electrolyte solutions can change due to solvent loss processes. An electrochemical balancing cell can be used to combat volume variability. Methods for altering the volume of one or more electrolyte solutions can include: providing a first electrochemical balancing cell containing a membrane disposed between two half-cells, establishing fluid communication between a first aqueous electrolyte solution of a flow battery system and a first half-cell of the first electrochemical balancing cell, and applying a current to the first electrochemical balancing cell to change a concentration of one or more components in the first aqueous electrolyte solution. Applying the current causes water to migrate across the membrane, either to or from the first aqueous electrolyte solution, and a rate of water migration is a function of current.
