Abstract
Corrosion mitigation in a battery may include displacing a first flowable medium with a second flowable medium along a first electrode to interrupt fluid communication of the first flowable medium with the first electrode—thus interrupting operation of the battery—while a second electrode remains in contact with a flowable medium (e.g., one or more of the first flowable medium or another flowable medium, such as a gel). For example, a membrane (e.g., an underwater oleophobic material) may be disposed between the first electrode and the second electrode. An oil may displace an aqueous electrolyte on a first side of the membrane toward a metallic electrode while the aqueous form of the electrolyte remains in contact with an air electrode on a second side of the separator membrane disposed toward the air electrode.
