1. A metal air battery, comprising:
a body containing an electrolyte;
a metal anode disposed on a first surface of the body;
a cathode formed within a second surface of the body opposite the first surface, 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; and
a barrier layer configured to prevent the ambient air from entering the interior portions of the body through the plurality of macroporous pathways of the carbon-based textured scaffold when the barrier layer is disposed over an exterior surface of the cathode and seals the plurality of macroporous pathways, wherein removal of the barrier layer from the exterior surface of the cathode is configured to activate the metal air battery by allowing the ambient air to enter the cathode and the interior portions of the body through the plurality of macroporous pathways.
