    Abstract: An electrochemical system and method are disclosed for On Site Generation (OSG) of oxidants, such as free available chlorine, mixed oxidants and persulfate. Operation at high current density, using at least a diamond anode, provides for higher current efficiency, extended lifetime operation, and improved cost efficiency. High current density operation, in either a single pass or recycle mode, provides for rapid generation of oxidants, with high current efficiency, which potentially allows for more compact systems. Beneficially, operation in reverse polarity for a short cleaning cycle manages scaling, provides for improved efficiency and electrode lifetime and allows for use of impure feedstocks without requiring water softeners. Systems have application for generation of chlorine or other oxidants, including mixed oxidants providing high disinfection rate per unit of oxidant, e.g. for water treatment to remove microorganisms or for degradation of organics in industrial waste water.

First and second solid portions protruding respectively from the first and second substrates are solid-state bonded together to form a solid state joint. By the solid state joint, the first and second substrates are joined together such that transmission membranes of the first and second substrates are mutually spaced by a predetermined distance, to form an overlapping portion. In the overlapping portion, an observation window is formed at a position where the first through holes face each other, and an accommodating part is formed between a lid member and the first substrate through the second through hole. One of negative and positive electrode active materials is provided in the accommodating part, and the other is provided between the transmission membranes of the observation window.

  • Patent number: 9536679
    Abstract: A method of manufacturing trenched electrochemical double layer capacitors is provided. One aspect of the method employs state-of-the art processes used in semi-conductor wafer manufacturing such as photolithography etching for creating trenches in the electrodes of the double layer capacitor. Another aspect of the method employs a die-saw process, which is scalable and low-cost. The trenched super/ultra capacitors made by the disclosed methods have the combined advantage of higher energy storage capacity than conventional planar super/ultra capacitors due to the increased surface area and higher power density than commonly used Li-ion batteries due to the faster charging time and higher instantaneous energy burst power. The manufacturing processes also have the advantage of better manufacturability, scalability and reduced manufacturing cost.
