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...

High-Entropy Engineering of Phosphate Based Polyanion Cathode Materials for Sodium-Ion Batteries: Advances and Perspectives.

Sodium-ion batteries (SIBs) are promising alternatives to lithium-ion batteries for large-scale energy storage due to their cost-effectiveness and resource abundance. However, conventional phosphate-based polyanionic cathodes suffer from low energy density, poor ion/electron conductivity, sluggish Na+ diffusion and cyc...
