NaV(PO)-decorated NaV(PO)F as a high-rate and cycle-stable cathode material for sodium ion batteries.

Since NaV(PO) (NVP) possesses modest volume deformation and three-dimensional ion diffusion channels, it is a potential sodium-ion battery cathode material that has been extensively researched. Nonetheless, NVP still endures the consequences of poor electronic conductivity and low voltage platforms, which need to be further improved. On this basis, a high voltage platform NaV(PO)F was introduced to form a composite with NVP to increase the energy density.
