Abstract

A general polymer-assisted spinodal decomposition strategy is used to prepare hierarchically porous sodium super ionic conductor (NASICON)-structured polyanion-type materials (e.g., Na₃V₂(PO₄)₃, Li₃V₂(PO₄)₃, K₃V₂(PO₄)₃, Na₄MnV(PO₄)₃, and Na₂TiV(PO₄)₃) in a tetrahydrofuran/ethanol/H₂O synthesis system. Depending on the boiling point of solvents, the selective evaporation of the solvents induces both macrophase separation via spinodal decomposition and mesophase separation via self-assembly of inorganic precursors and amphiphilic block copolymers, leading to the formation of hierarchically porous structures. The resulting hierarchically porous Na₃V₂(PO₄)₃ possessing large specific surface area (≈77 m² g⁻¹) and pore volume (≈0.272 cm³ g⁻¹) shows a high specific capacity of 117.6 mAh g⁻¹ at 0.1 C achieving the theoretical value and a long cycling life with 77% capacity retention over 1000 cycles at 5 C. This method presented here can open a facile avenue to synthesize other hierarchically porous polyanion-type materials.
