Ethylene Glycol Diethyl Ether (EGDE) is a linear ether solvent commonly used in advanced lithium-based battery electrolytes as a co-solvent or diluent. Its high oxidative stability and low viscosity make it ideal for improving ionic conductivity and facilitating lithium-ion transport, especially in high-voltage or dilute electrolyte systems. EGDE is particularly useful in electrolyte formulations for lithium-sulfur and lithium-metal batteries, where it helps balance solvent polarity and optimize interfacial stability.

Supplied at battery-grade purity, EGDE enables tunable electrolyte performance across a wide range of electrochemical applications.
