  • Patent number: 10522849
    Abstract: The present invention relates to an electrochemical cell having a channel-type flow-electrode unit. The channel-type flow-electrode structure according to the present invention, which has at least two channel-type flow-electrode units, can significantly reduce manufacturing costs and installation space by reducing the number of parts while extending the electrode capacity to be suitable for large-scale plants for electricity generation, energy storage, desalination, etc. In addition, the channel-type flow-electrode structure can be applied not only to a capacitive flow-electrode device and/or a redox flow battery device, but also to all of the devices for electricity generation, energy storage, and desalination while moving ions or protons.

  • Patent number: 10005970
    Abstract: A technique for treating heavy hydrocarbon oil in the oil production process or oil refining process. A method and apparatus for adding and mixing a liquid phase of hydrocarbon oil to a hydrocarbon oil feedstock containing heavy hydrocarbon oil in an oil production process or oil refining process including a hydrocarbon oil dehydration process, thereby processing the heavy hydrocarbon oil to be lighter and thus increasing the throughput of the heavy hydrocarbon oil.

  • Patent number: 9963363
    Abstract: The present invention uses the principles of electrochemical ion absorption (charging) and ion desorption (discharge), and relates to a continuous flow-electrode system, a high-capacity energy storage system, and a water treatment method using the same, in which high-capacity electric energy is stored as electrode materials of a slurry phase and electrolytes simultaneously flow in a successive manner within a fine flow channel structure formed on an electrode. More specifically, the present invention relates to a continuous flow-electrode system, an energy storage system, and a water treatment method, wherein electrode active materials consecutively flow in a slurry state whereby a high capacity is easily obtained without enlarging or stacking electrodes.

  • Publication number: 20120167983
    Abstract: A composite light converter for polycrystalline silicon solar cell and silicon solar cell using the converter includes a composite light converter disposed on the surface of a polycrystalline solar cell and connected by the electrode ribbon; upper and lower ethylene-vinyl acetate (EVA) sheets disposed such that the solar cell and the composite light converter are disposed between the EVA sheets; a low iron tempered glass disposed on the upper EVA sheet to transmit light; and a back sheet disposed under the lower EVA sheet and formed of a fluorine film or a PET film. Here, the composite light converter is a polymer binder containing light-emitting components, in which a polymer layer is formed on the surface of a polycrystalline silicon wafer comprising an electrode; the polymer layer is formed of two types of nano inorganic components that are active filling materials inside the converter.
