Abstract
A method for fabricating cylindrical and prismatic rechargeable metal-air batteries is devised. The method includes using micro fans to control air flowing through the batteries via air pathways between the packs of electrodes and separator sheet. The air pathways are created by protrusions printed or molded on plastic spacer film. The air is used by the positive electrode for generating electricity when the metal-air battery is discharged. By conjunction of a second positive electrode and an energy storage device, the micro fans can be actuated as soon as the metal-air battery is demanded by a load. The in-cell air management can not only supply air for reactions but also shut the system to preserve materials when they are not in service.
