Application

1.0 M NaPF6 in propylene carbonate (PC), battery grade is a ready to use electrolyte for sodium-ion batteries.[1],[2] It is one of the best performing electrolytes, especially for hard carbon anodes.[3] Propylene carbonate is an excellent solvent with a lower melting point (-49 °C) than other carbonates, making it suitable for low-temperature applications. For use with sodium metal anodes, much improved performance can be achieved by combining this electrolyte with 5 wt% fluoroethylene carbonate (FEC), which stabilizes the surface of the anode.[4]
