Polymer-assisted spinodal decomposition enabling a three-dimensional interconnected porous Na3.4Fe2.4(PO4)1.4P2O7@C material for enhanced sodium-ion batteries

Abstract Na4Fe3(PO4)2P2O7 (NFPP), an Iron-based mixed polyanion phosphate, is regarded as a potential cathode material for sodium-ion batteries. However, the application is often constrained by the inherently sluggish Na+ diffusion and low electronic conductivity. Herein, we synthesized a 3D interco...
