Ionic Conductor Armored Li3V2(PO4)3: A Robust Electrode for Lithium Capture via Capacitive Desalination

Abstract

The poor ionic conductivity and sluggish interfacial kinetics of Li3V2(PO4)3 (LVP) severely limit its practical use for lithium extraction from brines. To overcome these limitations, we developed a robust amorphous Li3PO4 coating for LVP. This coating enhances ionic conductivity, accelerates interfacial kinetics, and improves structural stability. Consequently, the modified LVP achieves a high Li+ adsorption capacity of 6.48 mmol g-1 within 150 mg L-1 LiCl at 1.2 V with excellent selectivity in simulated brines.
