ABSTRACT:
The present invention is directed to the fabrication of thin aluminum anode batteries using a highly reproducible process that enables high volume manufacturing of the galvanic cells. In the present invention, semiconductor fabrication methods are used to fabricate aluminum galvanic cells, wherein a catalytic material to be used as the cathode is deposited on a substrate and an insulating spacing material is deposited on the cathode and patterned using photolithography. The spacing material can either be used as a sacrificial layer to expose the electrodes or serve as a support for one of the electrodes. Similarly, the aluminum anode may be deposited and patterned on another substrate and bonded to the first substrate, or can be deposited directly on the insulating material prior to patterning. The cell is packaged and connected to a delivery system to provide delivery of the electrolyte when activation of the cell is desired.
