Scalable and Economic Synthesis of High-Performance Na3V2

Na3V2(PO4)2F3 has been emerging as one of the most promising cathodes for sodium-ion batteries due to its stable NASICON structure and fast Na diffusion. However present methods for preparation of Na3V2(PO4)2F3 suffer from either high energy consumption or generating poor rate performance. Herein a cost-effective solvothermal–ball-milling method is proposed to solve the problem. In the
