Patent number: 12064728Abstract: An electrodeionization filter includes: a housing having a water inlet and a water outlet; a first electrode installed inside the housing in a spiral shape; a second electrode installed inside the housing in a spiral shape so as to be spaced apart from the first electrode; and an ion exchange module installed between the first electrode and the second electrode for adsorbing or desorbing ionic substances contained in water introduced by an application of electricity. At least one of the first electrode and the second electrode has a structure in which a center portion thereof is denser than a peripheral region thereof. Accordingly, the lifespan of the electrodes of the electrodeionization filter can be increased, and the assembly of the electrodes and related parts can be easily facilitated.Type: GrantFiled: January 8, 2019Date of Patent: August 20, 2024Assignee: COWAY Co., Ltd.Inventors: Sang-Young Lee, Sang-Hyeon Kang, Chul-Ho Kim, Tae-Seong Kwon, Hyoung-Min Moon, Sung-Min Moon, Jun-Young Lee, Byoung-Phil Lee, Byung-Sun Mo, Guk-Won Lee

Publication number: 20240274827Abstract: An anode for a secondary battery includes an anode current collector, a first anode mixture layer on at least one surface of the anode current collector, and a second anode mixture layer on the first anode mixture layer. The first anode mixture layer includes a first silicon-based active material having a carbon coating layer formed on a surface, and a first conductive material, the second anode mixture layer includes a second silicon-based active material doped with a metal, and a second conductive material, and the anode for a secondary battery exhibits a Radial Breathing Mode (RBM) peak in a Raman spectrum obtained from a surface of the second anode mixture layer. An influence of volume expansion/contraction of a silicon-based active material during battery charging/discharging may be alleviated.Type: ApplicationFiled: February 5, 2024Publication date: August 15, 2024Inventors: Hyo Mi KIM, Seong Cho KWON, Moon Sung KIM, Sang Baek RYU, Da Hye PARK, Sang Won PARK, Sang In BANG, Seung Hyun YOOK, Hyun Ji LEE, Hwan Ho JANG, Da Bin CHUNG, Jun Hee HAN

Publication number: 20100311852Abstract: Disclosed is a preparing method for melamine-formaldehyde spheres (MFSs). The preparing method for MFS according to the present invention comprises mixing melamine in an aqueous formaldehyde solution and heating the solution to prepare a melamine-formaldehyde resin; admixing the melamine-formaldehyde resin with a surfactant, agitating the mixture, and centrifuging the mixture to prepare a solid powder; and washing the solid powder with an aqueous ethanol solution and drying the wetted solid powder to obtain the melamine-formaldehyde sphere. Regulating agitation speed of a mixture may control a size of the melamine-formaldehyde sphere. The preparing method for MFS according to the present invention may further comprise carbonizing the melamine-formaldehyde sphere after obtaining the melamine-formaldehyde sphere. Controlling a temperature for carbonization may control an amount of pores contained in the melamine-formaldehyde sphere.Type: ApplicationFiled: November 27, 2009Publication date: December 9, 2010Applicant: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: JEUNG-KU KANG, SE-YUN KIM, JUNG-HOON CHOI, JUN-HO KWON
