Enabling high-voltage stability of P2-type layered oxide cathodes using ionic liquid electrolytes

The high-voltage performance of sodium-ion batteries is strongly influenced by electrolyte chemistry, as parasitic reactions at the cathode interface can accelerate capacity loss. For layered oxide cathodes, the instability of the cathode-electrolyte interphase (CEI) becomes more severe at elevated voltages. Thus, opti...
