WebTFE will construct H-bonds with H 2 O in Zn 2+ solvation structures and results in low ionic association due to the electron-withdrawing effect of -CF 3 groups in TFE molecules. Therefore, Zn anodes in such electrolyte display a fast Zn 2+ plating/stripping kinetics and high Coulombic efficiency.
