Higher energy and safer sodium ion batteries via an electrochemically made disordered Na3V2(PO4)2F3 material

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.
