Guy Rampel 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).

  • Pasted positive electrode and process for its production
    Patent number: 6489058
    Abstract: The present invention provides a positive electrode for a rechargeable cell including a two-dimensional electrically conductive substrate supporting a coating comprising nickel hydroxide and a binder, preferably a styrene-ethylene/butylene-styrene triblock copolymer binder. The coating is formed by applying a paste to the two-dimensional substrate surface. The present invention also includes the cell made therefrom. The present invention further provides a method of producing this electrode including the steps of forming the paste and coating the paste onto the two-dimensional substrate. The capacity, midpoint voltage and power delivery of the coated electrode are comparable to or exceed those of traditional sintered and foam positive electrodes.
    Type: Grant
    Filed: February 15, 2000
    Date of Patent: December 3, 2002
    Assignee: Moltech Power Systems
    Inventors: John J. Weckesser, Canan Balaban, Vincent J. Puglisi, Robert Czajkowski, Guy Rampel, James Waggoner, Chao Y. Wu

  • Rechargeable electrodes utilizing unsintered fluorocarbon binder
    Patent number: 3954501
    Abstract: Polytetrafluoroethylene in aqueous dispersion is mixed with a finely divided electrochemically active rechargeable electrode material, such as zinc, zinc oxide, cadmium, cadmium oxide, nickel oxide, copper, copper oxide, silver, silver oxide, mercuric oxide, etc. The dispersion is broken by drying, freezing, solvent extraction, etc. Where zinc particles form the active material it may be desirable to amalgamate the zinc with mercury.
