Patent number: 8709635Abstract: The present invention provides a galvanic cell having an aluminum anode and a cathode compartment design suitable for carrying out the aqueous electrochemical reaction between solid aluminum metal and aqueous peroxide ions. The galvanic cell is activated when water, aqueous hydroxide solution, or an aqueous salt solution is added to the cell. This reaction releases a significant amount of electrochemical energy from a small size (mass or volume) cell. This cell reaction and design leads to an improvement in energy released over state-of-the-art aluminum/hydrogen peroxide galvanic cells.Type: GrantFiled: September 19, 2012Date of Patent: April 29, 2014Assignee: University of South FloridaInventors: Robert Frederick Benson, Andres M.

Patent number: 8597821Abstract: 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.Type: GrantFiled: October 1, 2010Date of Patent: December 3, 2013Assignee: University of South FloridaInventors: Andres M.
