Fluoroethylene Carbonate: Bis(2,2,2,) Trifluoroethyl Carbonate

Increasing the upper cut-off voltage is an intriguing approach to achieve even higher energy density in lithium ion batteries. However, poor oxidation stability of the state-of-the-art electrolytes leads to transition metal dissolution (TMD), migration, and deposition (TMDMD) on the negative electrode, followed by sudden and rapid capacity fade.
