摘要：

In this paper, we used first principle calculation and experimental investigation for exploring the application of Na3V2(PO4)(2)F-3. The influence of insertion and extraction of Na was investigated using XRD analysis. Results indicated the Na3V2(PO4)(2)F-3 owing a stable lattice structure with unit cell volume. The desodiated phase of the Na3V2(PO4)(2)F-3 could remain a stable state until 700 degrees C, which provide an excellent stability for battery electrode fabrication. The experimental study showed the Na3V2(PO4)(2)F-3 could serve as an excellent candidate for rechargeable Na battery fabrication.
