1. A battery comprising:
a metal anode and a cathode disposed on opposite sides of a body, the cathode comprising a carbon-based textured scaffold including a plurality of macroporous pathways configured to distribute oxygen and water vapor supplied by ambient air throughout the cathode and into interior portions of the body;
a nano-fibrous membrane (NFM) disposed between the cathode and the metal anode, the NFM including one or more dry salts configured to produce a liquid electrolyte when exposed to water vapor delivered by the plurality of macroporous pathways of the cathode; and
a hygroscopic interphase layer disposed between the cathode and the NFM, the hygroscopic interphase layer including a plurality of microporous pathways configured to drain excess quantities of the water vapor from the cathode and hydrate the one or more dry salts with the water vapor.
