TTE (1,1,2,2-Tetrafluoroethyl 2,2,3,3-tetrafluoropropylether, or HFE-458), is mainly used to enhance the safety and improve the interfacial stability of advanced battery chemistries, such as Lithium Metal Batteries (LMBs). TTE is characterized by having a high percentage of fluorine atoms (C–F bonds), which gives it its unique properties compared to conventional non-fluorinated ether or carbonate solvents, such as (1) Non-Flammability and Safety; (2) Stabilization of Lithium Metal Anodes (LMA).
