Toward Robust Anion-Derived Interphases: A Novel Ternary-Solvent Electrolyte for High-Voltage Fast-Charging Sodium Batteries.
Conventional carbonate electrolytes suffer from severe oxidative decomposition and unstable interphases for NaNi1/3Fe1/3Mn1/3O2 (NaNFM) cathode under high-voltage and fast-charging condition. Herein, an anion-derived interphase strategy is designed via synergistic solvation structure regulation utilizing sulfolane (SL)...
