Patent number: 6984295Abstract: An electrolytic process of ozone generation using platinum-coated titanium grid as cathode, ?-PbO2 deposited on the grid as anode, and batteries in conjunction with supercapacitors as a DC power source is described. No membrane is required to separate the electrodes, and a neutral salt such as NaCl is used to enhance the generation of ozone gas. The electrolytic apparatus comprising a cell, the electrodes, and a bubbler can also be inserted directly in water that needs ozone treatment. As batteries can power the ozone generation, the apparatus can be disposed at point-of-use and away from the city electricity. The electrolytic apparatus can be used for sterilization of water for pharmaceutical industry, household water supply, for surface cleaning of semiconductors, meats, fish, fruits, as well as for disinfection of SPA water and personal hygiene.Type: GrantFiled: February 6, 2002Date of Patent: January 10, 2006Assignee: Luxon Energy Devices CorporationInventors: Lin-Ren Shiue, Chia-Chann Shiue, Hsing-Chen Chung, Fei-Chen Hsieh, Yu-His Hsieh, Jiung-Jau Jou

Patent number: 6661643Abstract: Deionizers using the electrode configurations of electrochemical capacitors are described, wherein the deionizing process is called capacitive deionization (CDI). During deionization, a DC electric field is applied to the cells and ions are adsorbed on the electrodes with a potential being developed across the electrodes. As electrosorption reaches a maximum or the cell voltage is built up to the applied voltage, the CDI electrodes are regenerated quickly and quantitatively by energy discharge to storage devices such as supercapacitors. In conjunction with a carousel or Ferris wheel design, the CDI electrodes can simultaneously and continuously undergo deionization and regeneration. By the responsive regeneration, the CDI electrodes can perform direct purification on solutions with salt content higher than seawater. More importantly, electrodes are restored, energy is recovered and contaminants are retained at regeneration, while regeneration requires no chemicals and produces no pollution.Type: GrantFiled: October 18, 2002Date of Patent: December 9, 2003Assignee: Luxon Energy Devices CorporationInventors: Lih-Ren Shiue, Abel Sun, Chia-Chann Shiue, Fei-Chen Hsieh, Yu-His Hsieh, Jiung-Jau Jou

Patent number: 6512667Abstract: Using thin-films of iron oxide as the active material of electrodes, supercapacitors are fabricated on various substrates in different shapes. By chemical oxidation the iron-oxide film is formed directly and conformably on the substrates in a short period of cooking. The iron oxide has a chemical composition of FexOyHz, where 1.0≦x≦3.0, 0.0≦y≦4.0, and 0.0≦z≦1.0. Substrates, as the current collector, tested includes Al, Ti, Fe, Cu and Ni. Measurements by cyclic voltammetry indicates that the iron-oxide electrodes in a selected electrolyte can store charges as high as 0.5 F/cm2 or 417 F/g of the electrode materials. Supercapacitors as prepared are economical and can be used as enclosure housings for portable electronics, power tools, and batteries. The supercapacitors can also be integrated with the frames and chassis of electric vehicles.Type: GrantFiled: February 15, 2001Date of Patent: January 28, 2003Assignee: Luxon Energy Devices CorporationInventors: Lih-Ren Shiue, Dien-Shi Wu, Ching-Wen Chao, Jiung-Jau Jou
