Synthesis and Application of an Aromatic Sulfonate Sodium Salt for Aqueous Sodium-Ion Battery Electrolytes
Graphical Abstract
A new aromatic sodium salt, sodium (2,3,5,6-tetrafluorophenoxy) diethane sulfonate, bearing two sodium sulfonate groups is designed, synthesized, and characterized for application in water-based Na-ion batteries. The aqueous solution of the salt provides high ionic conductivity, suitable electrochemical stability and good cycling stability of Na-ion batteries, triggering new ideas for the development of water-based Na-ion battery electrolytes.
