1. A lithium-air battery, comprising:
an anode;
a cathode formed of an arrangement of carbonaceous structures and positioned opposite the anode, the cathode including:
a plurality of pores defined by a first group of the carbonaceous structures, the pores configured to allow oxygen supplied by ambient air to enter the cathode;
a plurality of interconnected pathways defined by a second group of the carbonaceous structures, the interconnected pathways configured to diffuse the oxygen throughout the cathode; and
one or more cavities formed within each of the pathways, each cavity configured to store lithium metal;
an electrolyte dispersed throughout the cathode, the electrolyte in fluid contact with the anode; and
one or more openings configured to selectively expose at least some of the plurality of pores to the ambient air.
