Cation-Anion Co-doped Na₃V₂(PO₄)₃ Cathode for Robust and High-Performance Sodium-Ion Storage.

ABSTRACT: Sodium ion superconductors (NASICON) are widely perceived as potential cathodes for sodium-ion batteries (SIBs) because of their good structural stability and high operation potential for Na⁺ de/intercalation. Nevertheless, the limited sodium ion storage capacity, rate capability, and stability due to the poor electronic conductivity hinder their widespread application. In this work, cation (Fe³⁺) and multivalent anion group (MoO₄ ^2-) are co-doped into Na₃V₂(PO₄)₃ (NVP) by replacing V³⁺ and PO₄ ^3-, producing a Fe³⁺/MoO₄ ^2-co-doped NVP, i.e., Na₃V_2-2xFe_2x(PO₄)_3-3x(MoO₄)
