Ultra‑Sodiophilic Mixed Conductor Interphase Enabling Uniform Top Deposition for Quasi‑Solid‑State Sodium‑Metal Batteries

Caption

  • A surface-induced “top” Na deposition mechanism facilitated by an ultra-sodiophilic ionic/electronic mixed conductor interphase composed of NaF and Na3Sb is proposed.
  • SFC-Na anode exhibits enhanced Na+ affinity force and accelerated ion transport kinetics, Na nucleation kinetics are greatly enhanced while dendrite growth is effectively suppressed.
  • The quasi-solid-state sodium-metal batteries with Na3V2(PO4)3 cathode and SFC-Na anode exhibit significantly enhanced cycling stability and superior rate capability.
