Tóm tắt

The ether-based electrolytes are acknowledged for their compatibility with a diverse array of sodium-ion battery anodes, as well as their capability to enable efficient and reversible electrochemical reactions. However, they encounter a challenge of oxidation at high voltages. We find that a standard diglyme-based electrolyte starts to oxidize and break down at voltages exceeding 3.9 V (vs. Na
