  • ULTRACAPACITORS COMPRISED OF MINERAL MICROTUBULES
    Publication number: 20100171081
    Abstract: Disclosed is an energy storage device having electrodes containing mineral microtubules. The electrodes may be formed, for example, from a paste containing microtubules, a conductive polymer containing mineral microtubules, or an aerogel containing the mineral microtubules. The mineral microtubules may be filled with carbon, a pseudocapacitance material, or a magnetoresistive material. The mineral microtubules may also be coated with a photoconductive material.
    Type: Application
    Filed: March 8, 2010
    Publication date: July 8, 2010
    Applicant: NaturalNano Research, Inc.
    Inventors: Robert D. Gunderman, John M. Hammond
  • Ultracapacitors comprised of mineral microtubules
    Patent number: 7679883
    Abstract: Disclosed is an ultracapacitor having electrodes containing mineral microtubules, an electrolyte between the electrodes, and a separator in the electrolyte to provide electrical insulation between the electrodes, while allowing ion flow within the electrolyte. The electrodes may be formed from a paste containing microtubules, a conductive polymer containing mineral microtubules, or an aerogel containing the mineral microtubules. The mineral microtubules may be filled with carbon, a pseudocapacitance material, or a magnetoresistive material. The mineral microtubules may also be coated with a photoconductive material.
    Type: Grant
    Filed: June 24, 2008
    Date of Patent: March 16, 2010
    Assignee: NaturalNano Research, Inc.
