  • Publication number: 20200006013
    Abstract: A supercapacitor apparatus within a sealed housing to provide a high-voltage EDLC energy storage unit includes cells stacked on one another, with each cell having a set of supercapacitors that are interconnected within the apparatus in a parallel-series configuration to provide an internally balanced energy storage unit that is capable of stand-off voltages of 10 volts or higher. The energy storage unit does not require balancing resistors or more complicated external balancing circuitry. The electrodes of the supercapacitors are comprised of carbon nanotubes and graphene nanoplatelets for optimal capacitance density. Along with providing higher stand-off voltages without the need for external balancing circuitry and increased volumetric energy density, the inventive energy storage unit provides for storage costs far lower than provided by currently available supercapacitor devices.

  • Publication number: 20190237650
    Abstract: The substrate and buffer layers, of either one-sided or two-sided superconducting tape, are separated from the YCBO layer(s) of the tape by a combined action of radiative or inductive heat and mechanical force via a reel-to-reel manufacturing process. The exfoliation process may also utilize an air blade(s) to facilitate the separation of the layers of the tape.

  • Publication number: 20190131512
    Abstract: A high-temperature superconducting filament and cable, and a method for manufacturing same. The substrate used to grow the superconducting layer is removed, and the exfoliated superconducting layer is coated with a protective layer, and then sliced into narrow strips. The strips are thereafter encapsulated with a conductive metal to provide a high-temperature superconducting filament. The filaments may be bundled together to provide a high-temperature superconducting cable.

  • Publication number: 20190094134
    Abstract: Provided is a method for sensing gases using a compact optical gas sensor, a method for manufacturing same and a method for performing measurement of gas concentration using the optical absorption signal. The sensor design features a two-mirror geometry with long optical path. The sensor utilizes both spectral and optical reference channels. The reference channels ensure long-term stability of the sensor, which makes the design especially suitable for demanding environments requiring high reliability over extended period of time. The sensor operation is based on absorption of infrared light by a gas volume. In order to accurately determine the gas concentration, the absorption of the light that passed through the gas volume is compared with the absorption of the light of a different wavelength and absorption of light that traveled a short light path. A dual-color LED is used as a two-wavelength compact radiation source. The LED changes the emission wavelength as the excitation current is changing direction.

  • Patent number: 9837814
    Abstract: A radio frequency-assisted fast superconducting switch is described. A superconductor is closely coupled to a radio frequency (RF) coil. To turn the switch “off,” i.e., to induce a transition to the normal, resistive state in the superconductor, a voltage burst is applied to the RF coil. This voltage burst is sufficient to induce a current in the coupled superconductor. The combination of the induced current with any other direct current flowing through the superconductor is sufficient to exceed the critical current of the superconductor at the operating temperature, inducing a transition to the normal, resistive state. A by-pass MOSFET may be configured in parallel with the superconductor to act as a current shunt, allowing the voltage across the superconductor to drop below a certain value, at which time the superconductor undergoes a transition to the superconducting state and the switch is reset.

  • Publication number: 20150255200
    Abstract: A superconducting magnetic energy storage device that can maintain a large ratio of the stored energy to the static energy loss, and has the ability to by-pass the current through a fast, high-voltage superconducting switch. More particularly, this invention relates to the design and application of novel high-voltage superconducting switch provided with a direct heating of the active superconducting layer through a metal substrate either by transport or by inductive current, and the protection of the superconducting layer by cryogenically-cooled metal-oxide-semiconductor field-effect transistors.

  • Patent number: 6794339
    Abstract: The present invention is a method of forming thick films of crystalline YBa2Cu3O7 that includes forming a precursor film comprising barium fluoride (BaF2), yttrium (Y) and copper (Cu). The precursor film is heat-treated at a temperature above 500° C. in the presence of oxygen, nitrogen and water vapor at sub-atmospheric pressure to form a crystalline structure. The crystalline structure is then annealed at about 500° C. in the presence of oxygen to form the crystalline YBa2Cu3O7 film. The YBa2Cu3O7 film formed by this method has a resistivity of from about 100 to about 600 &mgr;Ohm-cm at room temperature and a critical current density measured at 77 K in a magnetic field of 1 Tesla of about 1.0×105 Ampere per square centimeter (0.1 MA/cm2) or greater.
