Nonflammable Ether and Phosphate-Based Liquid Electrolytes for Sodium-Ion Batteries.

This study investigates a group of electrolytes containing NaPF or NaBF salts in phosphate- and ether-based solvents for high-mass loading sodium-ion batteries. It explores physicochemical properties such as ionic conductivity, dynamic viscosities, and nonflammability. The combination of experimental with computational studies reveals detailed insights into the physicochemical properties of the nonflammable liquid electrolytes.
