摘要：

We develop a microwave-assisted solid-phase synthesis (MASS) for Na3V2(PO4)2F3 (NVPF) using NH4F, NH4VO3, and Na2CO3 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-1 at 0.1C), retains 60.83 mA h g-1 at 20C, and shows 95.19% capacity retention after 500 cycles. Full cells (NVPF & Vert;HC) demonstrate industrial viability with 475.6 W h kg-1 energy density. This work provides a scalable, energy-efficient strategy for high-performance energy storage materials.
