Overview

Our 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropylether (TTE) is a high-purity, battery-grade fluorinated ether commonly used as an electrolyte solvent in lithium-ion batteries (LIBs). It is a clear liquid with a boiling point of 92 °C that is miscible with many polar organic solvents, including carbonates typically used in battery electrolytes. Our TTE is produced to meet the high standards of battery-grade purity, ensuring a minimum purity level of 99%, and is carefully purified to become anhydrous and acid-free, making it a reliable choice for battery applications.

Application：

1,1,2,2-Tetrafluoroethyl 2,2,3,3-tetrafluoropropylether (TTE) is a highly versatile fluorinated ether that finds its use as a co-solvent and additive in a range of battery systems, including lithium-sulfur batteries (LSBs) and lithium-ion batteries (LiBs). In LSBs, TTE plays a crucial role in reducing the solubility of intermediate lithium polysulfides, thereby preventing the polysulfide shuttle (PSS) effect and improving battery performance. Recent research suggests that TTE can also lead to the formation of a compact and uniform surface layer on the lithium anode when used as an additive, which improves the efficiency and stability of Li-S batteries. In LiBs, TTE acts as a cosolvent, reducing the viscosity of the electrolyte and enabling the use of lower concentrations of lithium salt without compromising ionic conductivity. Additionally, TTE has been shown to help form a stable, conductive solid electrolyte interphase (SEI) on both graphite anodes and NMC cathodes, thereby improving the overall electrochemical performance of the battery.
