Unlocking fast and highly reversible sodium storage in Fe-based mixed polyanion cathodes for low-cost and high-performance sodium-ion batteries

The iron-based polyanionic material Na 3 Fe 2 (PO 4 )P 2 O 7 is regarded as an excellent cathode due to its outstanding thermal stability and the three-dimensional (3D) open framework structure with facile sodium-ion transport. However, its inferior electronic conductivity and limited diffusion kine...
