Abstract

Regulation of the electronic structure of Na₃V₂(PO₄)₂F₃ (NVPF) via iron–manganese dual-doping enhances electrical conductivity and ion diffusion kinetics. Efficient charge transport and highly reversible Na⁺ de/intercalation in Fe-Mn dual-doped NVPF (FM-NVPF) enable exceptional rate capability and charge storage capacity. The full cell with the FM-NVPF cathode and hard carbon anode displays superior rate performance and cycling stability.
