Publication number: 20250079641Abstract: A separator for secondary batteries including a separator substrate having a porous structure, wherein the separator substrate comprises a polymer material. A coating layer is present on at least one surface of the separator substrate, wherein the coating layer includes a crystalline binder and an amorphous binder miscible with each other. The crystalline binder includes a first crystalline binder and a second crystalline binder, and an amount of the amorphous binder is 2 weight % to 5 weight % based on the total weight of a solid content of the coating layer, whereby the resistance in the coating layer of the separator is reduced and thus ionic conductivity is improved.Type: ApplicationFiled: October 6, 2022Publication date: March 6, 2025Applicant: LG ENERGY SOLUTION, LTD.Inventors: Ji Eun KIM, Dong Hun BAE, Hwan Ho SHIN, Jin Young SHIN, Yeo Ju YOON

Publication number: 20230087462Abstract: Data storage devices and operating methods that can improve a booting operation are disclosed. A storage device includes: a memory device including one or more boot partitions configured to store boot data for executing an operating system; and a memory controller coupled to the memory device and configured to perform, upon receiving power, a rebuild operation to restore first system data including active boot partition information associated with an activated boot partition among the one or more boot partitions and provide the active boot partition information to a host. Upon receiving, by the memory controller, from the host, a boot partition read request based on the active boot partition information, the memory controller transmits, to the host, the boot data stored in a boot partition corresponding to the active boot partition information.Type: ApplicationFiled: April 14, 2022Publication date: March 23, 2023Inventor: Ji Ho YOON

Patent number: 5672775Abstract: The present invention relates to a method of separating and purifying phenol in a simple and economical manner, by employing a step of adding high pressure carbon dioxide to the aqueous phenol solution to form a solid clathrate of phenol. According to the method of separating phenol of the present invention, phenol can be separated from the highly concentrated phenol solution without employing solvent or post-treatment step, finally to give 100 mole % of a solid phenol and 0.6 mole % of an aqueous phenol solution by employing only one step. Moreover, since the method is carried out at the temperature of below room temperature without excess energy consumption, the separation of phenol can be made in a simple and economical manner.Type: GrantFiled: January 29, 1996Date of Patent: September 30, 1997Assignee: Korea Advanced Institute of Science and TechnologyInventors: Huen Lee, Ji-Ho Yoon
