Ionic conductor armored Li<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub>: a robust electrode for lithium capture <i>via</i> capacitive desalination
The poor ionic conductivity and sluggish interfacial kinetics of Li<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> (LVP) severely limit its practical use for lithium extraction from brines. To overcome these limitations, we developed a robust amorphous Li<sub>3</sub>PO<sub>4</sub> coating for LVP. This coating enhances ionic conductivity, accelerates interfacial kinetics, and improves structural stability. Consequently, the modified LVP achieves a high Li<sup>+</sup> adsorption capacity of 6.48 mmol g<sup>-1</sup> within 150 mg L<sup>-1</sup> LiCl at 1.2 V with excellent selectivity in simulated brines.
