A Polymer-Assisted Spinodal Decomposition Strategy toward Interconnected Porous Sodium Super Ionic Conductor-Structured Polyanion-Type Materials and Their Application as a High-Power Sodium-Ion Battery Cathode.

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., Na₃ V₂ (PO₄ )₃ , Li₃ V₂ (PO₄ )₃ , K₃ V₂ (PO₄ )₃ , Na₄ MnV(PO₄ )₃ , and Na₂ TiV(PO₄ )₃ ) in a tetrahydrofuran/ethanol/H₂ O 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 forma
