Obtaining V2(PO4)3 by sodium extraction from single-phase NaxV2(PO4)3 (1 < x < 3) positive electrode materials - Nature Materials
Single-phase NaxV2(PO4)3 compositions obtained by annealing mixtures of Na3V2(PO4)3 and NaV2(PO4)3 enable the complete electrochemical extraction of Na+ through the activation of the V4+/V5+ couple. T...
