Rapid and efficient microwave-assisted solid-phase synthesis of Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>2</sub>F<sub>3</sub> and exploration of the synthesis process
We develop a microwave-assisted solid-phase synthesis (MASS) for Na<sub>3</sub>V<sub>2</sub>(PO<sub>4</sub>)<sub>2</sub>F<sub>3</sub> (NVPF) using NH<sub>4</sub>F, NH<sub>4</sub>VO<sub>3</sub>, and Na<sub>2</sub>CO<sub>3</sub> precursors, achieving ultrafast synthesis (40 minutes) and a fractal microstructure with uniform carbon coating. The NVPF cathode delivers near-theoretical capacity (127.41 mA h g<sup>-1</sup> at 0.1C), retains 60.83 mA h g<sup>-1</sup> at 20C, and shows 95.19% capacity retention after 500 cycles. Full cells (NVPF‖HC) demonstrate industrial viability with 475.6 W h kg<sup>-1</sup> energy density. This work provides a scalable, energy-efficient strategy for high-performance energy storage materials.
