Abstract
In some implementations, a metal air battery includes a metal anode, a cathode, a body, a nano-fibrous membrane (NFM), and a hygroscopic interphase layer disposed between the cathode and the NFM. The cathode may be a carbon-based textured scaffold including a plurality of macroporous pathways to distribute oxygen and water vapor supplied by ambient air throughout the cathode and into interior portions of the body. The NFM may include dry salts to produce a liquid electrolyte when exposed to water vapor delivered by the macroporous pathways of the cathode. The hygroscopic interphase layer may include a plurality of microporous pathways configured to drain excess quantities of the water vapor from the cathode and hydrate the dry salts with the water vapor.
