Jeffery Wolfenstine has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9653729
    Abstract: A lithium carbon monofluoride-oxygen battery is provided that includes a lithium metal-containing electroactive anode; an electroactive cathode formed of a carbon monofluoride compound; an electrolyte solution formed of an organic solvent and a lithium salt; a casing surrounding the anode, the cathode, and the electrolyte solution; and a port bored through the casing wherein the port selectively allows the flow of gas into the casing. In addition, a method of using an electrochemical battery is provided that includes providing a lithium carbon monofluoride-oxygen battery; closing the valve of the electrochemical battery to block the flow of gas into the battery; discharging the electrochemical battery after closing the valve of the battery; opening the valve of the electrochemical battery after discharging the electrochemical battery to expose the cathode to the flow of oxygen containing gas; and discharging the electrochemical battery after opening the valve of the electrochemical battery.

  • Patent number: 8961833
    Abstract: A lithium/fluorinated carbon (Li/CFx) battery having a composite cathode including an electroactive cathode material, a non-electroactive additive, a conductive agent, and a binder. The electroactive cathode material is a single fluorinated carbon having a general formula of CFx, whereby x is an averaged value ranging from about 0.5 to about 1.2. The non-electroactive additive is at least one or a mixture of two or more oxides selected from the group comprising Mg, B, Al, Si, Cu, Zn, Y, Ti, Zr, Fe, Co, or Ni. The conductive agent is selected from the group comprising carbon, metals, and mixtures thereof. Finally, the binder is an amorphous polymer selected from the group comprising fluorinated polymers, ethylene-propylene-diene (EPDM) rubbers, styrene butadiene rubbers (SBR), poly (acrylonitrile-methyl methacrylate), carboxymethyl celluloses (CMC), and polyvinyl alcohol (PVA).
