Patent number: 11987861Abstract: A method according to an embodiment is for recovering a valuable metal from a waste electrode material of a lithium secondary battery by using lithium carbonate. An anode-cathode mixed electrode material that has been separated by draining, crushing, screening, and sorting a waste lithium secondary battery is preprocessed. A precipitation operation performed by adding lithium carbonate (Li2CO3) to a metal melt acquired by performing sulfuric acid dissolution using sulfuric acid. A valuable metal such as nickel, cobalt, manganese, aluminum, and copper is recovered as a residue in the form of a carbonate composite, and a lithium sulfate (Li2SO4) aqueous solution including lithium is recovered as a filtrate.Type: GrantFiled: May 21, 2021Date of Patent: May 21, 2024Assignee: ECOPRO INNOVATION CO., LTD.Inventors: Suk Joon Park, Myung Gyu Lee, Jeong Sik Hong, So Yeong Byun, Gwang Seok Lee, Jong Sun Park, Beom Seok Seo, Min Woo Lee, Da Mo A Kim, Hui Sang Kim, A Ram Park

Publication number: 20020066492Abstract: A conduit pipe is installed within a cable tunnel and telecommunication cables are disposed in the conduit pipe. The conduit pipe is divided longitudinally into a plurality of divided bodies. Each divided body is equipped at one longitudinal side with a retaining part and at the other longitudinal side with a protruded part. A single conduit pipe is formed when the divided bodies are connected to each other along the longitudinal side. Since the divided bodies can be wound around a small-diameter bobbin to be carried, the space for their custody is reduced and the carriage thereof is easier. Further, since connection parts on surfaces of the conduit pipes can be arranged such that they occupy empty spaces between conduit pipes, the space occupied by the connection parts can be minimized, thereby comparatively larger number of telecommunication cables being able to be disposed within the cable tunnel.Type: ApplicationFiled: February 8, 2001Publication date: June 6, 2002Inventors: Young-Sug Kang, Geu-Bok Kim, Yong-Kun Noh, Myung-Woo Seo, Jeong-Kwen Park
