Abstract
Some embodiments provide energy storage systems that comprise: a first electrode; a second electrode; an electrolyte; the first electrode, the second electrode and the electrolyte are positioned such that the electrolyte is in contact with at least the first electrode; and a polarity reversal system electrically coupled with the first electrode and the second electrode, wherein the polarity reversal system is configured to allow the energy storage system to operate while a first polarity to charge and discharge electrical energy while operating in the first polarity, and the polarity reversal system is configured to reverse the voltage polarity across the first and second electrodes to a second polarity to allow the energy storage system to continue to operate while the second polarity is established across the first electrode and the second electrode to continue to charge and discharge electrical energy while operating in the second polarity.
