Na3V2(PO4)2F3 has been emerging as one of the most promising cathodes for sodiumion 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 costeffective solvothermal–ballmilling method is proposed to solve the problem.
