1.0M LiFSI in FEC/TEGDME=3:7 (v/v) Lithium Battery Electrolyte (KLD-FS01)

This electrolyte is formulated as a 1.0 M solution of lithium bis(fluorosulfonyl)imide (LiFSI) in a mixed solvent system of fluoroethylene carbonate (FEC) and tetraethylene glycol dimethyl ether (TEGDME) at a 3:7 volume ratio. Designed for advanced lithium battery research, it combines the high ionic conductivity and thermal stability of LiFSI with the SEI-forming benefits of FEC and the improved solvation capability of TEGDME. This composition is particularly suited for studies on lithium metal anodes, high-voltage cathodes, and lithium-sulfur chemistries. Available in five scalable package sizes from 50 g to 1000 g, it facilitates reproducible testing in academic and industrial laboratories. As a ready-to-use electrolyte, it supports consistent evaluation of electrochemical performance without the need for in-house formulation.
