Claim 15:
16. A redox flow battery system, comprising:
a redox flow battery,
an electrolyte storage tank fluidly connected to the redox flow battery,
an electrolyte pump fluidly connected between the electrolyte storage tank and the redox flow battery, and
a controller, including executable instructions stored in non-transitory memory thereon to,
interrupt 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
circulating deionized water through the redox flow battery,
returning the positive and negative electrolyte to the redox flow battery, and
resume cycling of the redox flow battery.
