Abstract[English]
A cell (100) for enhancing a lithium (Li) concentration in a stream includes a housing (102); a dense lithium selective membrane (108) located in the housing (102) and dividing the housing (102) into a first compartment (104) and a second compartment (106); a cathode electrode (105) located in the first compartment (104); an anode electrode (107) located in the second compartment (106); a first piping circuit (116) fluidly connected to the second compartment (106) and configured to supply a feed stream (110) to the second compartment (106); a second piping circuit (124) fluidly connected to the first compartment (104) and configured to circulate an enrichment stream (120) through the first compartment (104); and a power source (109) configured to apply a voltage between the cathode electrode and the anode electrode to initiate an oxidative electrochemical reaction on the anode electrode and a reductive electrochemical reaction on the cathode electrode. The dense lithium selective membrane has a thickness less than 400.[French]
Une cellule (100), permettant d'améliorer une concentration en lithium (Li) dans un courant, comprend une enveloppe (102) ; une membrane dense sélective au lithium (108) située dans l'enveloppe (102) et divisant l'enveloppe (102) en un premier compartiment (104) et un second compartiment (106) ; une électrode de cathode (105) située dans le premier compartiment (104) ; une électrode d'anode (107) située dans le second compartiment (106) ; un premier circuit de tuyauterie (116) en communication fluidique avec le second compartiment (106) et conçu pour alimenter en courant d'alimentation (110) le second compartiment (106) ; un second circuit de tuyauterie (124) en communication fluidique avec le premier compartiment (104) et conçu pour faire circuler un courant d'enrichissement (120) à travers le premier compartiment (104) ; et une source d'alimentation électrique (109) conçue pour appliquer une tension entre l'électrode de cathode et l'électrode d'anode, afin de déclencher une réaction électrochimique oxydative sur l'électrode d'anode et une réaction électrochimique réductive sur l'électrode de cathode. La membrane dense sélective au lithium présente une épaisseur inférieure à 400.
