Gerald F. Bubnick 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).

  • Cell having mixed solid cathode materials for controlling cell expansion on discharge
    Patent number: 4379815
    Abstract: A galvanic cell employing a consumable anode such as lithium, a cathode that expands during cell discharge and an electrolyte, wherein the improvement is that the cathode is composed of a physical mixture of at least two solid active materials having different expansion characteristics on cell discharge and selected such that the cathode mixture has a volumetric expansion substantially equal to the volumetric contraction of the anode thereby providing a cell that will have a substantially constant physical configuration during discharge.
    Type: Grant
