  • Patent number: 11251475
    Abstract: Corrosion mitigation in a metal-air battery includes displacing an electrolyte within a gap of the metal-air battery with a liquid. The liquid may be substantially nonreactive with the electrolyte, and the anode of the metal-air battery is less reactive with the liquid than with the electrolyte. Upon displacement of the electrolyte from the gap, the liquid may remain in the gap of the metal-air battery to reduce the likelihood of corrosion of the anode and, therefore, reduce the power drain of the battery resulting from such corrosion. To return the metal-air battery to an activated state for generating power, the electrolyte may be moved back into the gap to displace the liquid. A fluid circuit may be in fluid communication with the gap and may displace one of the liquid and the electrolyte in the gap with the other one of the liquid and the electrolyte from the fluid circuit.
