Fe-Doped Non-stoichiometric Na3.4Co2.4(PO4)1.4P2O7 Cathode for High-Energy-Density Sodium-Ion Batteries.

Na4Co3(PO4)2P2O7 is a representative mixed polyanionic cathode with a high operating voltage and high energy density. However, insufficient cycling stability is the core bottleneck constraining the widespread application of sodium-ion batteries (SIBs). Herein, we propose a synergistic strategy that combines non-stoichi...
