Tuning Na+ Solvation and Association in Fluorine-Free NaClO4 Electrolytes via Carbonate Cosolvents
Fluorine-free electrolytes are increasingly pursued for sodium-ion batteries (SIBs) to mitigate environmental and safety concerns associated with per- and polyfluoroalkyl substance (PFAS)-containing salts. However, the molecular mechanisms governing ion transport in sodium perchlorate (NaClO4)-based electrolytes remain...
