  • Publication number: 20100155261
    Abstract: A deionization apparatus for regenerating electrodes using vibration and a method of controlling the same. The deionization apparatus includes electrodes to which ions contained in a fluid are absorbed, and a piezoelectric element to separate the ions absorbed to the electrodes by vibration. Since the ions absorbed to the electrodes are separated using mechanical energy generated by the piezoelectric element, it may be possible to more rapidly perform regeneration of the electrodes.

  • Publication number: 20100116666
    Abstract: An electrode and a method for fabricating the same are disclosed. The method includes adding carbon nanotubes to a mixed solution of nitric acid and sulfuric acid and subjecting the carbon nanotube solution to microwaves for surface treatment resulting in facilitating the surface treatment, subjecting the carbon nanotube solution to ultrasonic waves to disperse the carbon nanotubes resulting in increasing the dispersion effect, subjecting the carbon nanotube solution to filtration and drying the carbon nanotubes to obtain a carbon nanotube plate mold.

  • Publication number: 20090223825
    Abstract: An electrode module, and more particularly, an electrode module capable of improving productivity by integrally bonding a current collector and a pair of electrodes using a protective film is provided. The electrode module includes a current collector to receive power from an external power supply, and a pair of electrodes to receive power from the current collector, in which the current collector and electrodes are integrally bonded by thermocompression using a protective film.

  • Publication number: 20090107842
    Abstract: A method to manufacture a carbon fiber electrode comprises synthesizing polyamic acid (PAA) as a polyimide (PI) precursor from pryomellitic dian hydride (PMDA) and oxydianiline (ODA) as monomers and triethylamine (TEA) as a catalyst, adding dimethylformamide (DMF) to the polyamic acid (PAA) solution to prepare a spinning solution and subjecting the spinning solution to electrostatic spinning at a high voltage to obtain a PAA nanofiber paper, converting the PAA nanofiber paper into a polyimide (PI) nanofiber paper by heating, and converting the polyimide (PI) nanofiber paper into a carbon nanofiber (CNF) paper by heating under an Ar atmosphere. Also, the method to manufacture a polyimide carbon nanofiber electrode and/or a carbon nanotube composite electrode may utilize carbon nanofibers having diameters that are lessened by optimizing electrostatic spinning in order to improve spinnability.
