Abstract: Systems and methods are provided for a redox flow battery. In one example, a method for the redox flow battery includes operating the redox flow battery in a short-term idle mode by discharging the redox flow battery at a constant current density over a duration of the short-term idle mode. By discharging the current density, a plated surface at a negative electrode of the redox flow battery may be maintained.

Abstract: Systems and methods are provided for a redox flow battery. In one example, a method for the redox flow battery includes operating the redox flow battery in a short-term idle mode by discharging a current density as a pulse of a duration shorter than a duration of the short term idle mode. By discharging the current density, a plating surface at a negative electrode of the redox flow battery system may be maintained.
