Abstract:
A method for fabricating a metal-air battery, comprising the steps of:providing a laminated compound material including a metal anode sheet, a separator sheet, a spacer sheet having a plurality of protrusions, and a cathode sheet; providing a positive electrode and a negative electrode; forming a cell core having a plurality of air pathways by a roll of the laminated compound material Wrapped concentrically around the positive electrode; and providing a plurality of micro pumps near at least one end of the cell core; wherein the air pathways are formed by the protrusions pressed against the cathode sheet, and air is drawn by the micro pumps into the air pathways, which becomes a cathode reactant connecting to the positive electrode, and the metal anode connects to the negative electrode.
