| 英文摘要 | Herein, a novel, highly efficient, and low -energy consumption four -stage ion -distillation of FCDI (ID-FCDI) device was developed that combined four commercial monovalent selective membranes with four flow electrode channels for high selectivity to extract Li + ions from salt lake. It exhibited excellent separation factor ( S Li + Mg 2+ = 11247.27), high enrichment ratio (4.95 times), super purity of Li + ion solution (99.97 %), and low molar energy consumption ( E m = 0.21 kWh mol -1 ) at mass ratio of Mg 2+ /Li + = 1:1. The mathematical model calculation revealed that the excellent selective separation effectiveness of the as -proposed ID-FCDI system is due to the unique property of the monovalent selectivity membranes, in which the transmembrane rate of lithium ions is ten times that of magnesium ions under the same condition. Furthermore, the separation mechanism of the asproposed ID-FCDI device for Li + /Mg 2+ ions was determined by the high electrosorption capacity of the flow electrode for Li + ions (1.14 times higher than Mg 2+ ions), low diffusion resistance (1.413 Omega), and high diffusion coefficient of Li + ions (2.83 times faster than Mg 2+ ions) by electrochemical measurement. On this basis, 3.92 times of lithium was successfully enriched in the natural salt lake brine of Golmud (mass ratio of Mg 2+ /Li + = 79.29), and the separation factor was 6307.17 with a 99.64 % purity of Li + ion solution and an E m of 0.20 kWh mol -1 . Finally, the Li 2 CO 3 product (99.66 %) was precipitated via the reaction between Na 2 CO 3 and the enriched Li + ion solution, consequently fulfilling the battery -level application of the industrial purity requirements. These findings highlight that this device is promising and profitable for lithium extraction from salt lake in industrial production. |
