  • Method of forming a dielectric through electrodeposition on an electrode for a capacitor
    Patent number: 10087541
    Abstract: The present invention relates to a method for forming a capacitor having carbon or metal electrodes and an electrolyte which is also a source of electropolymerisable anions. Applying a sufficiently positive voltage, a thin dielectric layer forms at the positive electrode, enabling the use of cell voltages higher than 3.5 V. The construction and characteristics of capacitors with 5, 6.3, and 10 V of cell voltages, having reduced graphene oxide electrodes and an ionic liquid electrolyte, are shown.
    Type: Grant
    Filed: September 29, 2015
    Date of Patent: October 2, 2018
    Assignee: University of Tartu
    Inventors: Tavo Romann, Enn Lust, Ove Oll
  • Separators, electrodes, half-cells, and cells of electrical energy storage devices
    Patent number: 9951443
    Abstract: Electrodes, separators, half-cells, and full cells of electrical energy storage devices are made with electrospinning and isostatic compression. The electrical energy storage device may include electrochemical double layer capacitors (EDLCs, also known as “supercapacitors”), hybrid supercapacitors (“HSCs”), Li-ion capacitors and electrochemical storage devices, Na-ion capacitors and electrochemical storage devices, polymer electrolyte fuel cells, and still other capacitors and electrochemical storage cells.

  • Method for preparation of the solid oxide fuel cell single cell
    Patent number: 8367273
    Abstract: There are disclosed a method for preparation of the solid oxide fuel cell single cell and a single cell with nano (micro) meso porous cathode electrode that are operational from 723 to 1073 K. The cathode electrode of the single cell possesses very large surface area (10-500 m2 g?1) with the hierarchical nano (micro) mesoporous structure, very high catalytic activity and very low oxygen electroreduction activation energy varying from 0.3-0.8 eV at ?0.2 . . . 0 V cathode electrode potential versus porous Pt/O2 reference electrode in air.
