Higher energy and safer sodium ion batteries via an electrochemically made disordered Na₃V₂(PO₄)₂F₃ material, Published online: 04 February 2019; doi:10.1038/s41467-019-08359-y

Na3V2(PO4)2F3 is a promising cathode material for Na-ion batteries, although its third sodium is usually not accessible electrochemically. Here the authors realize a disordered tetragonal NVPF phase, which can reversibly uptake 3 Na-ions and enables improved energy density for the NVPF/C full cell.
