Abstract
A method for operating a metal-hydrogen battery includes monitoring an indicator of degeneration of the metal-hydrogen battery during normal cycles of discharge and charge; determining whether the energy efficiency of the metal-hydrogen battery during normal cycles of discharge and charge is decayed based on the indicator; and in response to determining that the metal-hydrogen battery during normal cycles of discharge and charge is decayed due to oxidation, regenerating the metal-hydrogen battery.
Claims22
A method for operating a metal-hydrogen battery, the method comprising:
- monitoring an indicator of degradation of the metal-hydrogen battery during normal cycles of discharge and charge;
- determining whether the metal-hydrogen battery during normal cycles of discharge and charge is decayed based on the indicator;
- and
- in response to determining that the energy efficiency of the metal-hydrogen battery during normal cycles of discharge and charge is decayed due to anode oxidation, regenerating the metal-hydrogen battery,
- wherein the indicator is a potential on an anode of the metal-hydrogen battery, and
- wherein the metal-hydrogen battery during the normal cycles of discharge and charge is determined to be decayed when the potential on the anode of the metal-hydrogen battery is greater than a threshold voltage.
A metal-hydrogen battery, comprising:
- a vessel;
- at least one cell comprising a cathode and an anode, the anode and the cathode each having a catalyst, the at least one cell contained within the vessel, the at least one cell supporting a hydrogen evolution reaction (HER) and a hydrogen oxidation reaction (HOR) during charge and discharge cycles;
- an electrolyte contained in the vessel;
- and
- a controller coupled to the at least one cell, the controller executing instructions to monitor an indicator of degradation of the metal-hydrogen battery during normal cycles of discharge and charge;
- determine whether the metal-hydrogen battery during the normal cycles of discharge and charge is decayed based on the indicator;
- and
- in response to determining that the metal-hydrogen battery during the normal cycles of discharge and charge is decayed due to anode oxidation, regenerate the metal-hydrogen battery,
- wherein the indicator is a potential on the anode of the metal-hydrogen battery, and wherein the metal-hydrogen battery during the normal cycles of discharge and charge is determined to be decayed when the potential on the anode of the metal-hydrogen battery is greater than a threshold voltage.
