Superior Electrochemical Performance and Storage Mechanism of Na 3 V 2 (PO 4 ) 3 Cathode for Room‐Temperature Sodium‐Ion Batteries

A Na3V2(PO4)3/C composite with 3.8 wt.% carbon, which was synthesized by a one-step solid state reaction, exhibits Na storage capacity of 107 mAh g−1 and high coulombic efficiency of 99.8% in a new NaFSI/PC electrolyte. In situ XRD results reveal its sodium storage mechanism as a typical two-phase r... View More
