Abstract
- Electrochemical Li+ extraction technology applied to salt lake brine has received considerable attention in recent years for its low energy consumption and low emissions. However, the current electrochemical Li+ extraction method often requires the use of anion trapping electrodes or anion exchange membranes, which reduce their working lives and adaptabilities. To solve these problems, this study proposes a high Mg2+/Li+ ratio brine electrochemical Li+ extraction method based on the LiFePO4-Zn battery system. By discharging in the brine and charging in a ZnCl2 solution, the Li+ in the brine was successfully transferred to the ZnCl2 solution.
