1.0M NaPF6 in EC/TEGDME/DMC=4:4:2 (v/v) with 5% FEC Sodium Battery Electrolyte (KLD-NF36)

This electrolyte formulation is developed for sodium-ion battery research, featuring 1.0 M NaPF6 dissolved in a mixed solvent system of ethylene carbonate (EC), tetraethylene glycol dimethyl ether (TEGDME), and dimethyl carbonate (DMC) at a 4:4:2 volume ratio, with 5.0% fluoroethylene carbonate (FEC) as an additive. The ether-based primary solvent (TEGDME) provides compatibility with sodium metal anodes and hard carbon, while the carbonate co-solvents adjust viscosity and ionic conductivity. FEC helps stabilize the solid-electrolyte interphase, improving cycling performance. This blend is commonly used in coin-cell or pouch-cell evaluations for optimizing sodium battery electrolytes, particularly in studies focusing on interfacial stability and rate capability. Offered by Canrd under model MA-EN-ET-0689, it is available in multiple gram-scale quantities suitable for laboratory-scale experiments.
